Abstract

Previously, we have shown that mycobacterial heat shock protein 70 (HSP70)-derived peptide B29 induces B29-specific regulatory T cells, which suppressed experimental arthritis in mice by cross-recognition of their mammalian HSP70 homologs (1). The aim of this study is to characterize the B29 binding and specific CD4(+) T cell responses in the context of human MHC molecules (HLA). Binding of B29 peptide and its mammalian homologs to HLA molecules was examined with competitive binding assays. The effect of B29 immunization was assessed in proteoglycan-induced arthritis in HLA-DQ8 transgenic mice, followed by ex vivo restimulation with B29 to examine the T cell response. Human PBMC were used to investigate the presence of B29-specific T cells with immunoregulatory potential. We found a high to moderate binding affinity for multiple HLA-DR and HLA-DQ molecules, including those highly associated with rheumatoid arthritis. This binding was functional, as B29 immunization resulted in suppression of arthritis and T cell responses in HLA-DQ8 transgenic mice. In humans, we demonstrated the presence and expansion of B29-specific CD4(+) T cells, which were cross-reactive with the mammalian homologs. With HLA-DR4(+) tetramers specific for B29 or mB29b we showed expansion of cross-reactive T cells, especially the human CD4(+) CD25(+) FoxP3(+) T cell population after in vitro stimulation with B29. These results demonstrated a conserved fine-specificity and functionality of the B29-induced regulatory T cell responses in the context of the human MHC. Based on these findings, a translational path of the B29 experimental findings into a clinical immunomodulatory therapeutic approach comes within reach. This article is protected by copyright.

Abstract

01 mei 2012, Contains fulltext : 108202.pdf (publisher's version ) (Closed access), Identifying genetic variants influencing human brain structures may reveal new biological mechanisms underlying cognition and neuropsychiatric illness. The volume of the hippocampus is a biomarker of incipient Alzheimer's disease and is reduced in schizophrenia, major depression and mesial temporal lobe epilepsy. Whereas many brain imaging phenotypes are highly heritable, identifying and replicating genetic influences has been difficult, as small effects and the high costs of magnetic resonance imaging (MRI) have led to underpowered studies. Here we report genome-wide association meta-analyses and replication for mean bilateral hippocampal, total brain and intracranial volumes from a large multinational consortium. The intergenic variant rs7294919 was associated with hippocampal volume (12q24.22; N = 21,151; P = 6.70 x 10(-16)) and the expression levels of the positional candidate gene TESC in brain tissue. Additionally, rs10784502, located within HMGA2, was associated with intracranial volume (12q14.3; N = 15,782; P = 1.12 x 10(-12)). We also identified a suggestive association with total brain volume at rs10494373 within DDR2 (1q23.3; N = 6,500; P = 5.81 x 10(-7)).

Abstract

Item does not contain fulltext, Cone dystrophy with supernormal rod response (CDSRR) is considered to be a very rare autosomal recessive retinal disorder. CDSRR is associated with mutations in KCNV2, a gene that encodes a modulatory subunit (Kv8.2) of a voltage-gated potassium channel. In this study, we found that KCNV2 mutations are present in a substantial fraction (2.2-4.3%) of a sample of 367 independent patients with a variety of initial clinical diagnoses of cone malfunction, indicating that CDSRR is underdiagnosed and more common than previously thought. In total, we identified 20 different KCNV2 mutations; 15 of them are novel. A new finding of this study is the substantial proportion of large deletions at the KCNV2 locus that accounts for 15.5% of the mutant alleles in our sample. We determined the breakpoints and size of all five different deletions, which ranged between 10.9 and 236.8 kb. Two deletions encompass the entire KCNV2 gene and one also includes the adjacent VLDLR gene. Furthermore, we investigated N-terminal amino acid substitution mutations for its effect on interaction with Kv2.1 using yeast two-hybrid technology. We found that these mutations dramatically reduce or abolish this interaction suggesting a lack of assembly of heteromeric Kv channels as one underlying pathomechanism of CDSRR. 32:1398-1406, 2011.

Abstract

Background In Kyrgyzstan, a low-middle income Central-Asia republic, breast cancer (BC) management does not meet minimal standards: ∼70% of women are diagnosed late and do not receive adequate treatments. Setting up BC services is a health priority. Methods In 2011, the Swiss Development Cooperation in Central Asia audited for a BC project in Kyrgyzstan. The audit found a dramatic situation in imaging, histologic diagnosis and treatment (local and systemic). A multi-step program was funded, supported by the European School of Oncology (ESO), the Swiss Cancer League and the Swiss Association against Cancer in close collaboration with the local ONG Ergene (Europa Donna member), the Swiss Embassy and the Kyrgyz Ministry of Health. The first priorities were mammographic and histologic diagnosis. From 2017, Swiss and Italian breast specialists periodically visited Kyrgyzstan to supply materials, teach health professionals and trace progress and problems; Kyrgyz doctors were trained in Switzerland and Italy, patients were provided educational support and devices (prostheses, wigs). Results Improvements were significant and fast. The mammography quality is now acceptable and the pathologists routinely assess hormonal receptors, HER-2 and Ki-67 expression and biomarkers for differentiating tumor subtypes. Diagnostic and therapeutic guidelines have been implemented with local physicians. Thanks to a Canadian government donation, two Linear Accelerators and one Computed Tomography for radiotherapy planning are being purchased, replacing old, unsafe equipment. A US ONG assisted in chemotherapy regimen implementation. Current steps involve training of radiation oncologists, medical physicists, technicians and surgeons in modern BC loco-regional approaches, discussing the availability of drugs of the WHO list of essential medicines, establishing tele pathology and mobile mammography. Conclusions The SILK project shows effective BC cooperative programs in low-middle income countries are feasible. Strict and continuous collaboration with local governments, organizations and health professionals is vital to ensure their success. SILK is a model adaptable and exportable to other critical situations across the world. Legal entity responsible for the study European School of Oncology.
