Regulation of axonal trafficking of membrane-bound compartments is important for delivery of various neuronal cargoes towards the distal synapses and for quality control of damaged cellular components/toxic proteins. The contribution of Rab GTPase pathways in neurodegenerative pathologies and the regulatory mechanism to replenish various Rab proteins in the axonal periphery remain unclear. In the Encalada lab, we modeled familial prion disease axonopathies in primary murine hippocampal neurons, to determine (1) the biogenesis pathway that forms neurotoxic mutant prion protein (PrPmut) aggregates and (2) the consequences of PrPmut aggregate formation on cytoskeletal-organelle interactions within swollen axons that PrPmut aggregates reside. Firstly, I, and the research team, identified that the small GTPase ARL8 recruits kinesin-1 and HOPS for axonal transport and fusion, respectively, that generates neurotoxic PrPmut aggregates in non-degradative endolysosomes, called 'endoggresomes.' This axonal rapid endosomal sorting and transport-dependent aggregation (ARESTA) mechanism forms endoggresomes rapidly, and as a result impair calcium dynamics and neuronal viability. Inhibition of ARESTA reduces axonal endoggresome densities and rescues neuronal dysfunction, providing an anti-aggregation target to ameliorate prionopathies. Secondly, axonal micro-domain analysis of live organelle dynamics within endoggresome sites showed deficits to the MT-based active transport system, that result in enhanced mitochondrial-Rab7 endosomal contacts that induce mitochondrial fission via Rab7 activity and render retained mitochondria dysfunctional. In the Davis lab, I studied post-transcriptional fate of rab GTPase mRNA towards their axonal localization and function at the Drosophila larval neuromuscular junction (NMJ) pre-synapse. I found that a conserved RNA-binding protein Imp and kinesin-1 are required for rab11 mRNA delivery to axon termini and are required for synaptic plasticity and unimpaired locomotory behavior. Furthermore, I detected transcripts of multiple important rab GTPases for endosome recycling at the axonal and glial periphery at the NMJ, uncovering an unorthodox regulatory mechanism of axonal membrane trafficking.

Very little is known about the enigmatic gigantopyramidal neuron in the Primary Motor Cortex. These Betz cells are the largest neurons in the human brain, display unique morphology, play a fundamental role in voluntary movement, and are selectively vulnerable to a range of neurodegenerative diseases, including Amyotrophic Lateral Sclerosis (ALS). Yet, there has been no targeted studies to investigate the molecular profile of these neurons and how that may be affected in disease. Here, for the first time, laser microdissected human Betz cells were subjected to extensive proteomic analysis via a workflow that has been optimised to produce leading proteomic performance from individually pooled neurons. The proteome of the Betz cell has been comparatively analysed to similar neurons to reveal key insights into their physiology. This thesis molecularly confirms previous assumptions about their biology and discovers cellular mechanisms that are enriched within these neurons. To complement proteomic findings, laser microdissected Betz cells were also subjected to RNA-sequencing to investigate their gene expression patterns, to validate recently generated proteomic observations, and for the first time, to reveal the transcriptome of the Betz cell. To ease and improve future Betz cell research, the proteomic/transcriptomic data were screened to search for Betz cells biomarkers - for which there are currently none that immunochemically target Betz cells without also binding to surrounding neurons. Several proteins were identified that could selectively target Betz cells, potentially acting Betz cell biomarkers. Finally, proteomic/transcriptomic analysis was also applied to microdissected Betz cells from ALS patients to determine how/why these neurons degenerate in ALS. The findings herein, align with the excitotoxicity hypothesis of ALS, i.e. that upper motor neurons become over-activated by excess glutamate activity. These data also provide clues to other pathways that may cause the degeneration of Betz cells in ALS e.g. DNA damage, oxidative stress, dysregulated energy production, and impaired axonal guidance.

The accurate repair of DNA damage is essential for protecting cells from undergoing cell death or accumulating mutations. The multi-topical work presented within this thesis focuses on the mechanistic study of DNA repair and sources of genome instability. Interstrand crosslinks (ICLs) are toxic DNA lesions that block the essential cellular processes of transcription and replication. The mechanisms of ICL repair pathways in non-dividing cells are poorly characterized. This study aims to determine the mechanisms for a transcription- associated ICL repair pathway. After developing an in vitro biochemical system to study ICL repair, it is demonstrated that the CSB transcription-coupled repair factor can directly stimulate the SNM1A exonuclease in the unhooking of ICLs. A novel functional stimulatory interaction between the XPF-ERCC1 endonuclease and the SNM1A exonuclease is also identified. The experiments described here suggest that transcription-associated repair of ICLs may result in formation of toxic DSBs that are repaired by non-homologous end joining. It was recently identified that cancer cells with microsatellite instability (MSI) undergo cell death after genetic knockdown of the Werner helicase (WRN), though the mechanism for this is unknown. We provide evidence that depletion of WRN in MSI cells generates DNA double- strand breaks (DSBs) at (TA)n microsatellite repeats. In MSI cancer cells, (TA)n microsatellite repeats undergo expansion and form stable non-B DNA cruciform structures. If these structures are not unwound by the WRN helicase, they are cleaved by the MUS81-EME1 nuclease, resulting in DSB formation across the genome. This study identifies expanded (TA)n repeats as a biomarker for MSI cells' synthetic lethal dependence on WRN and supports the concept of developing WRN inhibitors for the treatment of MSI cancers. Neurons are long-lived, post-mitotic cells that are believed to face high rates of endogenous DNA damage. Surprisingly little is known about the causes of endogenous DNA damage in neurons and where in the genome the damage occurs. We demonstrate that DNA single- strand breaks (SSBs) occur at neuronal enhancers. These SSBs are largely repaired through PARP1, XRCC1, and Pol β-dependent mechanisms. The sites of these breaks overlap with sites of TET-mediated oxidation of 5-methylcytosine, suggesting that demethylation of DNA could be the source of endogenous SSB formation at neuronal enhancers. This work highlights a novel research technique called S1-END-seq for the genomic mapping of DNA SSBs.

Alzheimer's disease (AD) is an insidious age-related neurodegenerative disease and the most common type of dementia. AD neuropathology typically involves the accumulation of extracellular plaques as well as intracellular neurofibrillary tangles that mainly consist of amyloid-beta (Abeta) and hyperphosphorylated tau aggregates, respectively. Previous studies in animal models lacking the expression of Mapt, which encodes for microtubule-associated protein tau that is implicated in AD neuropathology, demonstrated that Abeta-driven toxicity is tau-dependent. However, inconsistent reports of Abeta-driven toxicity in Mapt homozygous knockout (Mapt-/-) animal models have emerged while a human MAPT-/- model remains unavailable to corroborate whether tau is essential to mediate the toxic phenotypes caused by Abeta in human genetic backgrounds. In this thesis, I describe the generation of the first human MAPT-/- induced pluripotent stem cell (iPSC) lines in collaboration with the Cowley research group in Oxford. Two isogenic panels of MAPT-/-, MAPT+/- and MAPT+/+ iPSC lines, which were derived from two parental iPSC lines of healthy individuals, were identified. These iPSC lines were differentiated into cortical neurons in parallel and these neurons exhibited similar levels of cortical marker and synapse expression regardless of their MAPT genotypes. However, tau ablation in the iPSC-derived cortical neurons was sufficient to cause neurite outgrowth impairments, alterations in mitochondrial transport along axons, and reduced electrophysiological activities. Upon the exposure to extrinsic Abeta insults in the forms of synthetic oligomers or AD brain-derived Abeta, the MAPT+/+ neurons experienced cytotoxicity, reduced number of anterograde motile mitochondria along axons, synapse loss, and hyperactivation in vitro. These adverse phenotypes could be reversed in the MAPT-/- neurons whereas Abeta-induced neurite outgrowth impairments were not rescued in the MAPT-/- neurons. Notably, having a reduced dosage of tau expression in the MAPT+/- neurons was enough to be protective against cell death caused by Abeta. The study on Abeta-driven toxicity was extended to iPSC lines derived from the sporadic AD patients who participated in the Deep and Frequent Phenotyping pilot cohort. Synapse losses caused by extrinsic Abeta insults were quantified in thirteen lines of patient iPSC-derived cortical neurons and these neurons displayed varying levels of synaptic vulnerability to Abeta across patient lines. Their individual vulnerability to Abeta in vitro was demonstrated to reflect clinical vulnerability to Abeta burden measured by cognitive readouts from the same patients in vivo, suggesting that AD modelling with iPSCs is a tractable method to study individual levels of disease vulnerability. Here I present the experimental evidence on the effects of tau deletion in human iPSC-derived cortical neurons and show that tau is required in certain aspects of Abeta-driven toxicity. The clinical relevance of studying Abeta-driven toxicity using sporadic AD patient iPSC-derived cortical neurons was also investigated by demonstrating that individual clinical vulnerability to Abeta can be modelled in vitro using these neurons.

A large (GGGGCC) repeat expansion in C9ORF72 gene is the commonest genetic cause of amyotrophic lateral sclerosis (ALS). It causes both loss- and gain-of-function, but the relative contribution of the different mechanisms to the development of ALS remains uncertain. One of the pathomechanisms is the production of dipeptide repeat proteins (PR, PA, GR, GP and GA) via repeat-associated non-ATG translation (DPRs). Animal and cellular models have suggested that the arginine-rich DPRs are toxic, but staining in fixed brains of C9orf72 patients show that the same DPRs are not very abundant compared to GA, GP and PA. Moreover, the DPR-related phenotypes exhibited in in vitro models are not always verified in C9orf72 patients. For these reasons I developed a doxycycline-inducible lentiviral system to regulate DPR expression in induced pluripotent stem cell (iPSC)-derived motor neuron (MN) cultures. The effects of GA and PR expression in CRISPR/Cas9 corrected C9orf72 iPSC-derived MNs were compared to the phenotypes of C9orf72 mutant lines. Both DPRs were partially accountable for altered ER and mitochondrial calcium homeostasis, and stress granule formation. Moreover, PR expression may reduce maximal mitochondrial respiration, while GA induced lysosomal activation. The activation of chaperone-mediated autophagy cleared CRISPR/Cas9 corrected iPSC-derived MNs from GA and PR, but it did not rescue C9orf72 mutant lines. Moreover, I studied the effects of a peptide designed to reduce RNA foci, and I showed that it may improve mitochondrial respiration in C9orf72 mutant iPSC-derived MNs.

Amyotrophic lateral sclerosis is a devastating neurodegenerative disease which is clinically and aetiologically heterogenous. However, TDP-43 neuropathology is a unifying hallmark found in 97% of ALS cases. Understanding the common pathological pathways downstream of TDP-43 dysregulation is essential for the development of novel drug targets, and the development of a TDP-43 based biomarker for clinical translation would have profound implications for early diagnosis and monitoring of disease progression. The work presented in the first part of this thesis addresses the need to develop TDP-43 as a unifying disease-specific biomarker. Mass spectrometry was used to detect TDP-43 from insoluble protein fractions extracted from ALS post mortem tissue with TDP-43 pathology which led to the discovery of ALS disease-specific TDP-43 peptides. These peptides were then validated in an independent targeted proteomic experiment which, for the first time, allowed the quantification of disease-relevant peptides. This enabled the measurement of an ALS-specific TDP-43 peptide signal that reflects sites of pathological truncation and an increased C-terminal TDP-43 protein ratio. This now provides a platform with which to investigate ALS biofluids with the aim to ultimately develop a disease-specific TDP-43 in vivo assay for patient stratification. In the second part of the thesis I describe the use of affinity-enrichment mass spectrometry to investigate the human wild-type and M337V mutant TDP-43 interactome in a low expression (BAC)-transgenic mouse motor neuron model. I demonstrate that the C-terminal mutation of TDP-43 disrupts specific protein-protein interactions associated with human wild-type TDP-43. In response to oxidative stress, wild-type TDP-43 interactions shift towards proteins that are relevant to cellular stress pathways, while mutant TDP-43 is bound to proteins that are independently linked to pathways known to drive ALS pathogenesis. The key interactions that were disrupted by the M337V mutation involve proteins that are important for stress granule formation and extracellular vesicle secretion. Furthermore, I was able to demonstrate correlative phenotypic abnormalities in stress granule assembly and exosome secretion in motor neurons from the human TDP-43 (BAC)-transgenic mouse model and also in human iPSC-derived motor neurons with the same TDP-43 M337V mutation. In conclusion, work in this thesis provides significant novel data to support the further development of TDP-43 as an in vivo biomarker in ALS. Analysis of the TDP-43 interactome in a physiologically relevant mouse model has defined core cellular pathways matched to relevant phenotypes which will be important for the identification of pathways relevant for drug target development.

616.8 ,Nervous system--Degeneration - Abstract
A recent World Health Organisation Global Burden of Disease study reports a yearly increase in the prevalence of neurodegenerative diseases, with more than 100 million people worldwide expected to be living with dementia by 2050. These disorders represent a range of neurological conditions characterised by selective neuronal cell death; no effective treatments have been developed, with the available therapy only able to reduce the symptoms in some cases. Although etiology of neurodegenerative diseases is not well understood, some common pathological features are shared between them, including protein aggregation and oxidative stress. Identification of the molecular mechanisms underlying these processes would therefore deepen our understanding of the disease pathogenesis and help in the search for new therapeutic targets. Members of a conserved protein family (TLDc) have been shown in recent years to protect neurons from oxidative insults in vitro and in vivo and play a role in oxidative stress response regulation via unknown mechanism. In addition, TLDc mutations are causative in range of neurological disorders, some characterised by neurodegeneration. Therefore, further analysis of this particular protein family may provide new insights into fundamental protective mechanisms that could be harnessed in the future. The aim of this thesis was to investigate the mechanism of action of the TLDc protein oxidation resistance 1 (Oxr1) in oxidative stress protection and in the maintenance of neural tissue homeostasis. Using a combination of in vitro assays and in animal models with disruption or overexpression of Oxr1, I have shown that Oxr1 interacts with the potent antioxidant enzyme peroxiredoxin-2 where it regulates its post-translational modifications and oligomerisation in a brain-region specific manner. I have also for the first time discovered a molecular function of Oxr1 by showing it possesses holdase chaperone activity in vitro, suggesting it acts as a putative chaperone. Next, to understand the cause of neurodegeneration in the Oxr1 knockout mouse, transcriptional profiling was carried out, revealing an induction of presymptomatic neuroinflammatory markers, suggesting Oxr1 is critical for the normal inflammatory response in the brain. I have also produced preliminary data suggesting a role for Oxr1 in autophagy. Finally, computational analysis of transcriptional activity and regulation of TLDc family members suggests high degree of functional conservation between TLDc genes and their involvement in processes throughout the body, proposing novel directions for future studies. Together, my results contribute to our understanding of the functions of TLDc genes in the CNS and the role of Oxr1 in oxidative stress protection and proteostasis.

- Abstract
The remarkable family of proteins that can make us very ill—but can also be linked to long-term memory, immunity, and the origin of lifeOver the last decade, scientists have discovered the importance and widespread presence in the body of a remarkable family of proteins known as prion proteins. Research links various types of prion proteins to neurodegenerative diseases such as Parkinson's and Alzheimer's—and this has fueled the search for new drugs that could halt the progression of these terrible disorders. Other discoveries have revealed the essential roles prion proteins play in memory and immunity, and—in an extraordinary finding—the part they may have played in the beginnings of life on our planet. In this engaging and accessible book, Michel Brahic tells the story of these amazing and versatile proteins.Brahic, a leading researcher on diseases of the central nervous system, first describes the discovery of prions and their role in infection, beginning with early work on the animal disease scrapie and a mysterious human illness in New Guinea, apparently transmitted by cannibalism. Prions were eventually identified and named by Stanley Prusiner in the 1980s. (Brahic tells us Prusiner's alternate name for prion was “piaf.”) Prion proteins were then revealed as the cause of other illnesses, from “mad cow” disease and its human counterpart, Creutzfeldt-Jakob disease, to such noninfectious brain disorders as Parkinson's and Alzheimer's. While the prion proteins responsible for diseases are definitively “bad,” Brahic also explains that these abnormal prions are rare exceptions. Most of the time, prion proteins actually serve “good” and vital functions—and they may even have been present at the origin of life itself.

- Abstract
Degenerative nerve diseases are age-related, progressive and cause irreversible neurological loss that may lead to death. Chronic diseases like amyotrophic lateral sclerosis, Huntington rsquo;s disease, Alzheimer rsquo;s disease, and Parkinson rsquo;s disease are associated with insoluble protein depositions and pose serious health challenges that may intensify in the coming decades. Current therapies only help to alleviate some of the physical or mental symptoms associated with neurodegenerative diseases, although there is currently no remedy for slow disease progression. In recent years, attempts have been made to discover a mechanism for neurodegenerative diseases and prospective treatment that may help mitigate aging effects and prevent these diseases. Natural products have been a constant source of new approaches for the treatment of neurodegenerative diseases, in particular plant alkaloids and polyphenolic compounds.Indopathy for Neuroprotection: Recent Advances highlights herbal treatments that are preferred over conventional treatments in some regions. Book chapters focus on the effects of various medicinal plants that have shown promise in reversing pathological symptoms of neurodegenerative disease and highlight the neuroprotective role of medicinal herbal phytochemicals and their mechanism of action. The book serves as a reference for pharmacology and herbal medicine scholars as well as healthcare workers interested in information about alternative and complementary therapies for neurological disorders.

- Abstract
Multiple advanced neuroimaging applications in various neurodegenerative diseases including Parkinson's disease (PD), frontotemporal dementia (FTD), vascular dementia (VaD) and autism spectrum disorder (ASD) are covered in this book. Relatively novel techniques such as integrated PET/MRI and independent component analysis (ICA)-based dual regression (DR) methods were developed to capture multi-level molecular/functional and structural/microstructural as well as high-order inter-network coordination abnormalities. For instance, both PET dopamine transporter and striatal binding ratio reductions in the caudate and putamen were found in PD, consistent with the diffusion tensor imaging (DTI) fractional anisotropy (FA) reduction and fMRI voxel-mirrored homotopic correlation (VMHC) in the substantia nigra (swallow tail sign signature of PD). Furthermore, dopamine storage and pathway labeled with the vesicular monoamine transporter tracer identified decreased densities in the bilateral mesial temporal cortex, caudate, orbitofrontal cortex, left frontal and occipital cortices, consistent with the morphological atrophy, functional connectivity and conductivity deficits in PD. Similarly in FTD patients, the advanced MRI methods such as ICA-DR, VMHC, voxel-based morphometry (VBM) as well as PET tracer for amyloid accumulation and FDG glucose uptake identified typical brain atrophy, structural dis-connectivity, glucose hypometabolism, higher neuropathological burden, lower interhemispheric correlation as well as disrupted intra- and inter-network modulation in the orbitofrontal and anterior temporal cortices together with insular and frontoparietal networks, with the cerebellum and dorsolateral attentional network as typical compensations. Functional and structural abnormalities had further been elucidated in the VaD dependent participants and autistic children. For instance, both lower FA and VMHC, brain atrophy and functional connectivity deficits, demyelination, axonal degeneration and white matter integrity damage in several white matter tracts were present in the dependent compared to independent participants in VaD data cohort. Increased neuronal activity with higher global fractional amplitude of low frequency fluctuation (fALFF) in the conventional and slow-wave sub-band was confirmed with less efficiency of systematic integration in VaD dependent group. Moreover, in ASD compared to controls, regional gray matter volume and cortical thickness in all four brain lobes increased, whereas white matter volume were decreased in addition to the lower temporal, visual and superior frontal but higher inferior and dorsolateral prefrontal cortical functional connectivities exhibited in ASD. The differences in each type of disease could also be revealed with the same imaging method based on either unique region or distinct brain circuit inter-connection, using VMHC, ICA-DR, DTI, VBM, fALFF and graph-theory based small-worldness analysis. In this book, we have developed and generalized conventional and advanced imaging methodologies to several common neurodegenerative diseases. For instance, we have identified the unique imaging signature for each disease type and the underlying neuropathological mechanism connections with conductivity, structural and microstructural connectivity, intra- and inter-network correlation, systematic integration and efficiency analyses. Our objective, comprehensive and confirmative results indicated great potential in utilizing these quantifications for accurate disease classification and staging. With solid imaging evidence, thorough analysis and generalized applications, this book should capture the interests of readers in the broad fields of brain science, disease diagnosis and effective treatment.

- Abstract
Holbourne's theory that rotational head movement and shear strains were limiting factors in producing acute parenchymal brain damage was a watershed moment in understanding traumatic brain injury (TBI). Long term effects, and in particular neurodegenerative proteinopathy subsequent to TBI, remain theoretical, notwithstanding the poorly understood ‘punch drunk'syndrome of the early and mid-20th century, and the 21st century concept of chronic traumatic encephalopathy. This book, the Handbook of Traumatic Brain Injury and Neurodegeneration, has as its theme the marriage between neurodegenerative disease and neurotrauma through TBI surrogates such as sport, military service, and experimental models, and the legitimacy of that marriage. In the 32 contributions included here, this handbook not only explores the deleterious effects of genuine TBI, but also, and more importantly, the relationship between TBI and neurodegeneration. Controversy notwithstanding, there is much to be learned about the biological effects of TBI, substrates for long-term sequelae, the relationship between TBI and diverse neuropsychiatric disorders, and targets for therapy. The overall message to the neuroscience community from these papers may be a cautionary tale. The null hypothesis, that there is no causal relationship between TBI and progressive neurodegenerative disease, appears to be very much in play, and the book will be of interest to all those working in the field.

- Abstract
An estimated 80 million people live with a neurodegenerative disease. That number is expected to increase rapidly as populations age, lifespans increase, and exposure to toxins rises. Despite decades of research and billions in funding, there are no medications that can slow, much less stop, the progress of these diseases. This is because diseases such as Parkinson's and Alzheimer's do not exist in biology. Yet, hundreds of clinical trials around the world are examining the potential of single therapies in thousands of people sharing one of these labels. Compounding the problem, these therapies were developed on evidence from models that do not come close to capturing the complexity of these diseases in the affected humans. These practices must end. Brain Fables is a call to refocus on understanding living and aging to create the personalized treatments each affected individual desperately needs.

- Abstract
This book provides a comprehensive overview of the role of neuroglia in neurodegenerative diseases. Neuroglia are the most abundant cells in the nervous system and consist of several distinct cell types, such as astrocytes, oligodendrocytes,and microglia. Accumulating evidence suggests that neuroglia participate in the neurodegenerative process, and as such are essential players in a variety of diseases, including Alzheimer's, Parkinson's, and Huntington's. Intended for researchers and students, the book presents recent advances concerning the biology of neuroglia as well as their interaction with neurons during disease progression. In addition, to highlight the function of neuroglia in different types of neurodegenerative disease, it also discusses their mechanisms and effects on protecting or damaging neurons.

- Abstract
Neuroimaging techniques that can help elucidate and characterize the nature and mechanism of tissue injury and disease progression in neurodegenerative disease are of particular importance given its their roles in seeking successful preventive and therapeutic treatments. Studying large-scale samples with various disease mechanisms using multi-parametric imaging, as well as revealing the correlations between the neuroimaging metrics and clinical data including neurocognitive function and neuropsychological inventories to elucidate multiple factors affecting the neurodegeneration processes in brain are the main topics of this book. In addition, the neural underpins of cognitive and psychological functions with advanced functional imaging techniques can provide better cross-validation and clinical symptom relevance of multi-parametric data. Expanding the current findings with higher diagnosis accuracy and detection specificity in multiple neurodegenerative diseases as well as better differentiation of each type are the ultimate goal. The results in this book will extend the current notion of diagnosis value of various relatively new imaging techniques in multiple neurodegenerative diseases including traumatic brain injury, post-traumatic stress disorder, multiple sclerosis and early stage of Alzheimer's disease such as mild cognitive impairment. Specifically, the neurobiology and related imaging findings of the four representative neurodegenerative diseases will be introduced and reviewed, including brain region-specific and disease-related alterations, unique clinical symptom of each disease, as well as previous findings and challenges. There is an increasing body of literature suggesting that damage to the default mode network, hypothalamus, thalamus and hippocampus neuronal networks and local injuries might be under-diagnosed and may account for some of the sequelae following the neurodegenerative injuries including trauma and dementia. The relatively novel imaging results to differentiate each disease using advanced functional connectivity, neuronal activity, microstructure integrity analysis based on structural connectivity, multi-dimensional morphometry and molecular imaging tracers including amyloid and tau for neuropathological burden quantification were presented to differentiate each type of disease. We then briefly reviewed some of the therapeutic effects of traditional Chinese medicine with neuroimaging quantifications to help treating neurodegenerative diseases. Finally, our work proves that the multi-parametric neuroimaging methods with more than twelve metrics and numerous tight clinical association data presented in this book are the most forefront and up-to-date with enough sensitivity, precision and resolution. Taken together, multiple neuroimaging metrics haved been demonstrated in this book to identify and quantify significant and distinct brain alterations at function, microstructure, morphology and molecular scales in different types of neurodegenerative diseases with high sensitivity and specificity. These comprehensive imaging features could be combined to improve disease diagnosis accuracy. The aim of this book is thus intended to provide both beginners and experts in biomedical imaging and health care a broad and complete picture as well as the new developments of using multiple metrics in improving disease identification and diagnosis accuracy. This book would hopefully capture the interests of colleagues interested in neurodegenerative disease diagnosis and treatment, and could help convey the methodological and integrative perspectives of multi-parametric neuroimaging applications.

- Abstract
This book provides comprehensive coverage of small fiber neuropathy (SFN), from diagnosis to therapy. It focuses on nerve degeneration and neuropathic pain, and their underlying pathology, physiology, psychophysics, genetics and imaging. In particular, this book describes and discusses the major advances in diagnostic techniques for assessing SFN. These include skin biopsy, evoked potentials, quantitative sensory testing and functional studies, as biomarkers of SFN.SFN is a common peripheral nerve disorder, but was often overlooked due to a lack of objective and specific diagnostic tests for the assessment of small nerve fibers. These fibers mediate thermal sensation, pain detection (nociception), and autonomic regulation. Major symptoms of SFN include neuropathic pain, impaired sensation and autonomic dysfunction. Neuropathic pain poses a diagnostic challenge to clinicians, an essential step for selecting appropriate treatment to relieve suffering.SFN frequently develops in systemic diseases such as diabetes mellitus, following chemotherapy, infections etc., or presents as a major feature of various genetic neuropathies (e.g. channelopathy and familial amyloidosis). In addition to describing these conditions which lead to SFN, this book also describes related syndromes of neurodegeneration and pain, including fibromyalgia, visceral pain and hypersensitivity.This definitive book covers both clinical aspects and research progress, which provides in-depth and up-to-date information on SFN. It would be immensely useful for clinicians, neurologists, neuroscientists, diabetologists, and pain specialists.

- Abstract
It has become evident over the last years that abnormalities in RNA processing play a fundamental part in the pathogenesis of neurodegenerative diseases. Cellular viability depends on proper regulation of RNA metabolism and subsequent protein synthesis, which requires the interplay of many processes including transcription, pre--‐mRNA splicing, mRNA editing as well as mRNA stability, transport and translation. Dysfunction in any of these processes, often caused by mutations in the coding and non--‐ coding RNAs, can be very destructive to the cellular environment and consequently impair neural viability. The result of this RNA toxicity can lead to a toxic gain of function or a loss of function, depending on the nature of the mutation. For example, in repeat expansion disorders, such as the newly discovered hexanucleotide repeat expansion in theC9orf72 gene found in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD), a toxic gain of function leads to the formation of RNA foci and the sequestration of RNA binding proteins (RBPs). This in return leads to a loss of function of those RBPs, which is hypothesized to play a significant part in the disease progression of ALS and FTD. Other toxicities arising from repeat expansions are the formation of RNA foci, bi--‐directional transcription and production of repeat associated non--‐ATG (RAN) translation products.This book will touch upon most of these disease mechanisms triggered by aberrant RNA metabolism and will therefore provide a broad perspective of the role of RNA processing and its dysfunction in a variety of neurodegenerative disorders, including ALS, FTD, Alzheimer's disease, Huntington's disease, spinal muscular atrophy, myotonic dystrophy and ataxias. The proposed authors are leading scientists in the field and are expected to not only discuss their own work, but to be inclusive of historic as well as late breaking discoveries. The compiled chapters willtherefore provide a unique collection of novel studies and hypotheses aimed to describe the consequences of altered RNA processing events and its newest molecular players and pathways.

- Abstract
Neurodegenerative diseases are widespread disorders, with prevalence increasing with age. The first chapter of this book discusses autophagy, a cellular tool for the elimination of proteins that accumulate in neurodegenerative disorders and have pathogenetic significance. Parkinson's disease (PD) is one of the most common degenerative diseases of the central nervous system. Chapter Two examines evidence on impairment of social cognition in patients with PD. Chapter Three discusses how finding the molecular cause of the PD could contribute to early diagnosis, and facilitate the development of effective neuroprotective or modulatory drugs. The final chapter reviews the functional role of adult hippocampal neurogenesis in learning and memory, and how this form of structural plasticity is altered in neurodegenerative diseases known to involve cognitive impairment such as Alzheimer's disease, Parkinson's disease, and Huntington's disease.

In this text, new information about the structure of sigma 1 receptor, its binding sites are provided as well as its expression in many cell types. It's putative role in degenerative neuronal diseases including amyotrophic lateral sclerosis, Alzheimer's disease, Parkinson's disease, Huntington's disease, pain, drug addiction and locomotor activity. Their roles in possible treatments for blinding retinal diseases emphasize the tremendous far-reaching potential for ligands for these receptors. Exciting breakthroughs in this dynamic field in the last decade are reported herein, which will guide future investigators in determining the full potential of this unique, yet abundantly expressed protein.

- Abstract
Biometals in Neurodegenerative Diseases: Mechanisms and Therapeutics is an authoritative and timely resource bringing together the major findings in the field for ease of access to those working in the field or with an interest in metals and their role in brain function, disease, and as therapeutic targets. Chapters cover metals in Alzheimer's Disease, Parkinson's Disease, Motor Neuron Disease, Autism and lysosomal storage disorders. This book is written for academic researchers, clinicians and advanced graduate students studying or treating patients in neurodegeneration, neurochemistry, neurology and neurotoxicology. The scientific literature in this field is advancing rapidly, with approximately 300 publications per year adding to our knowledge of how biometals contribute to neurodegenerative diseases. Despite this rapid increase in our understanding of biometals in brain disease, the fields of biomedicine and neuroscience have often overlooked this information. The need to bring the research on biometals in neurodegeneration to the forefront of biomedical research is essential in order to understand neurodegenerative disease processes and develop effective therapeutics. - Authoritative and timely resource bringing together the major findings in the field for those with an interest in metals and their role in the brain function, disease, and as therapeutic targets - Written for academic researchers, clinicians, and advanced graduate students studying, or treating, patients in neurodegeneration, neurochemistry, neurology and neurotoxicology - Edited by international leaders in the field who have contributed greatly to the study of metals in neurodegenerative diseases
