Abstract Coronavirus disease 2019 (COVID-19, caused by severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2)) is primarily a respiratory illness. However, various extrapulmonary manifestations have been reported in patients with severe forms of COVID-19. Notably, SARS-CoV-2 was shown to directly trigger white adipose tissue (WAT) dysfunction, which in turn drives insulin resistance, dyslipidemia, and other adverse outcomes in patients with COVID-19. Although advanced age is the greatest risk factor for COVID-19 severity, published data on the impact of SARS-CoV-2 infection on WAT in aged individuals are scarce. Here, we characterized the response of subcutaneous and visceral WAT depots to SARS-CoV-2 infection in young adult and aged golden hamsters. In both age groups, infection was associated with a decrease in adipocyte size in the two WAT depots; this effect was partly due to changes in tissue’s lipid metabolism and persisted for longer in aged hamsters than in young-adult hamsters. In contrast, only the subcutaneous WAT depot contained crown-like structures (CLSs) in which dead adipocytes were surrounded by SARS-CoV-2-infected macrophages, some of them forming syncytial multinucleated cells. Importantly, older age predisposed to a unique manifestation of viral disease in the subcutaneous WAT depot during SARS-CoV-2 infection; the persistence of very large CLSs was indicative of an age-associated defect in the clearance of dead adipocytes by macrophages. Moreover, we uncovered age-related differences in plasma lipid profiles during SARS-CoV-2 infection. These data suggest that the WAT’s abnormal response to SARS-CoV-2 infection may contribute to the greater severity of COVID-19 observed in elderly patients.

Mounting evidence suggests that the gut-to-lung axis is critical during respiratory viral infections. We herein hypothesized that disruption of gut homeostasis during severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection may associate with early disease outcomes. To address this question, we took advantage of the Syrian hamster model. Our data confirmed that this model recapitulates some hallmark features of the human disease in the lungs. We further showed that SARS-CoV-2 infection associated with mild intestinal inflammation, relative alteration in intestinal barrier property and liver inflammation and altered lipid metabolism. These changes occurred concomitantly with an alteration of the gut microbiota composition over the course of infection, notably characterized by a higher relative abundance of deleterious bacterial taxa such as Enterobacteriaceae and Desulfovibrionaceae. Conversely, several members of the Ruminococcaceae and Lachnospiraceae families, including bacteria known to produce the fermentative products short-chain fatty acids (SCFAs), had a reduced relative proportion compared to non-infected controls. Accordingly, infection led to a transient decrease in systemic SCFA amounts. SCFA supplementation during infection had no effect on clinical and inflammatory parameters. Lastly, a strong correlation between some gut microbiota taxa and clinical and inflammation indices of SARS-CoV-2 infection severity was evidenced. Collectively, alteration of the gut microbiota correlates with disease severity in hamsters making this experimental model valuable for the design of interventional, gut microbiota-targeted, approaches for the control of COVID-19.

Monoclonal antibodies (mAbs) represent a rapidly growing pharmaceutical class of protein drugs that becomes an important part of the precision therapy. mAbs are characterized by their high specificity and affinity for the target antigen, which is mostly present on the cell surface. Ion channels are a large family of transmembrane proteins that control ion transport across the cell membrane. They are involved in almost all biological processes in both health and disease and are widely considered as prospective targets. However, no antibody-based drug targeting ion channel has been developed so far that has progressed to clinical use. Thus, we provide a comprehensive review of the elaborated mAbs against ion channels, describe their mechanisms of action, and discuss their therapeutic potential.

These data suggest that the WAT’s abnormal response to SARS-CoV-2 infection may contribute to the greater severity of COVID-19 observed in elderly patients., La maladie à coronavirus 2019 (COVID-19, causée par le syndrome respiratoire aigu sévère-coronavirus 2 (SRAS-CoV-2)) est principalement une maladie respiratoire. Cependant, diverses manifestations extrapulmonaires ont été signalées chez des patients atteints de formes graves de COVID-19. Il a notamment été démontré que le SRAS-CoV-2 déclenche directement le dysfonctionnement du tissu adipeux blanc (TAC), qui entraîne à son tour une résistance à l'insuline, une dyslipidémie et d'autres effets indésirables chez les patients atteints de COVID-19. Bien que l'âge avancé soit le facteur de risque le plus important pour la gravité de la COVID-19, les données publiées sur l'impact de l'infection par le SRAS-CoV-2 sur le tissu adipeux des personnes âgées sont rares. Nous avons caractérisé ici la réponse des dépôts de WAT sous-cutanés et viscéraux à l'infection par le SRAS-CoV-2 chez des hamsters dorés jeunes adultes et âgés. Dans les deux groupes d'âge, l'infection a été associée à une diminution de la taille des adipocytes dans les deux dépôts de WAT ; cet effet était en partie dû à des changements dans le métabolisme des lipides du tissu et a persisté plus longtemps chez les hamsters âgés que chez les jeunes adultes. En revanche, seul le dépôt de WAT sous-cutané contenait des structures en forme de couronne (CLS) dans lesquelles les adipocytes morts étaient entourés de macrophages infectés par le SRAS-CoV-2, certains d'entre eux formant des cellules syncytiales multinucléées. Il est important de noter que l'âge avancé prédisposait à une manifestation unique de la maladie virale dans le dépôt sous-cutané de WAT pendant l'infection par le SRAS-CoV-2 ; la persistance de très grandes CLSs indiquait un défaut associé à l'âge dans l'élimination des adipocytes morts par les macrophages. De plus, nous avons mis en évidence des différences liées à l'âge dans les profils lipidiques plasmatiques au cours de l'infection par le SRAS-CoV-2. Ces données suggèrent que la réponse anormale du WAT à l'infection par le SRAS-CoV-2 peut contribuer à la plus grande sévérité du COVID-19 observée chez les patients âgés.

The COVID-19 pandemic has more than 600 million reported cases worldwide and has resulted in more than 6 million deaths (as of September 2022). Men with COVID-19 have been found to be more likely than women to be hospitalized, admitted to intensive care, or die from the disease. Physiological effects of androgens are among the factors that may contribute to this difference. In addition, it is already known that the expression of the TMPRSS2 gene, which encodes a protease that is crucial for virus entry, is regulated by androgens in the prostate. Thus, the possible regulation of TMPRSS2 by androgens in the lung could explain, at least in part, the heightened severity observed in men with SARS-CoV-2.Our objective is to study the effect of gene expression modulation by androgens on SARS-CoV-2 infection and COVID-19 severity.We established a hormone-dependent prostate cell line stably overexpressing ACE2, the protein essential for SARS-CoV-2 infection, to be able to measure the effect of hormonal modulation of the TMPRSS2 gene on different stages of SARS-CoV-2 infection in vitro. The results demonstrate a hormone-dependent modulation of the cellular infection rate. More precisely, using pseudoviruses, we showed that this effect takes place during virus entry.In parallel, in vivo, in order to study the effect of androgens on SARS-CoV-2 infection and disease severity over time, we used a hamster model, for which we performed androgen suppression by castration. Our results show an earlier pulmonary inflammatory response in castrated hamsters, assessed by anatomo-pathological diagnosis, inflammatory cytokine monitoring and transcriptomic analysis. This kinetic shift in response to SARS-CoV-2 infection reveals an effect of androgens in the lung via an altered transcriptional program. In men, these results were supported by an analysis of the CACOVID cohort, which identifies patients with cancer, including prostate cancer treated or not with hormone therapy, who had been diagnosed with COVID-19.Together, these results indicate a role for androgens in the SARS-CoV-2 infection process and in particular in the kinetics of disease progression.; La pandémie de COVID-19 compte plus de 600 millions de cas recensés dans le monde et a fait plus de 6 millions de morts (chiffres en septembre 2022). Il a été constaté que les hommes atteints par la COVID-19 ont plus de risques que les femmes d'être hospitalisés, admis en soins intensifs ou de décéder de la maladie. Les effets physiologiques des androgènes figurent parmi les facteurs qui pourraient contribuer à cette différence. En outre, on sait déjà que l'expression du gène TMPRSS2, qui code une protéase cruciale dans l'entrée du virus, est régulée par les androgènes dans la prostate. Ainsi, la possible régulation de TMPRSS2 par les androgènes dans le poumon pourrait expliquer, au moins en partie, la sévérité accrue observée chez les hommes face au SARS-CoV-2.Notre objectif est d'étudier l'effet de la modulation d'expression des gènes par les androgènes, en particulier TMPRSS2, sur l'infection au SARS-CoV-2 et la sévérité de la COVID-19.Nous avons établi une lignée de cellules prostatiques hormono-dépendantes surexprimant stablement ACE2, la protéine indispensable à l'infection au SARS CoV 2, pour pouvoir mesurer l'effet de la modulation hormonale du gène TMPRSS2 sur différentes étapes de l'infection au SARS-CoV-2 in vitro. Les résultats démontrent une modulation du taux d'infection cellulaire de manière hormono-dépendante. Plus précisément, grâce à l'utilisation de pseudovirus, nous avons montré que cet effet a lieu lors de l'entrée du virus.En parallèle, in vivo, pour étudier l'effet des androgènes sur l'infection au SARS CoV-2 et la sévérité de la maladie au cours du temps, nous avons utilisé un modèle de hamster, pour lequel nous avons réalisé la suppression androgénique par castration. Nos résultats montrent une réponse inflammatoire pulmonaire plus précoce chez les hamsters castrés, évaluée à la fois par un diagnostic anatomo-pathologique, par le suivi de cytokines inflammatoires et par analyse transcriptomique. Ce décalage de cinétique en réponse à l'infection au SARS-CoV-2 révèle un effet des androgènes dans le poumon via un programme transcriptionnel modifié. Ces résultats ont été complétés par une analyse de la cohorte CACOVID.L'ensemble de ces résultats témoigne d'un rôle des androgènes dans le processus d'infection au SARS-CoV-2 et notamment dans la cinétique d'évolution de la maladie.

Members of the TRPM (“Melastatin”) family fall into the subclass of the TRP channels having varying permeability to Ca2+ and Mg2+, with three members of the TRPM family being chanzymes, which contain C-terminal enzyme domains. The role of different TRPM members has been shown in various cancers such as prostate cancer for mostly TRPM8 and TRPM2, breast cancer for mostly TRPM2 and TRPM7, and pancreatic cancer for TRPM2/7/8 channels. The role of TRPM5 channels has been shown in lung cancer, TRPM1 in melanoma, and TRPM4 channel in prostate cancer as well. Thus, the TRPM family of channels may represent an appealing target for the anticancer therapy.

- Abstract
• TRPV6 channel is (over)expressed in a number of human malignancies. • TRPV6 expression in cancer cells is regulated by VDR, AR, ER, and p38α. • TRPV6-triggered pathway reported so far is: Ca
2+ - calmodulin – calcineurin – NFaT. • TRPV6 is targeted by some compounds but only SOR-13 passed clinical phase I trials. Significant advances have been made during last two decades as to the discovery of TRPV6 channel expression in various tissues and particularly in cancer. Among them are the cancers of the epithelial origin such as of prostate, breast, pancreas, ovaries, endometrium, testicule, colon, and lung. Though its role in cancer cell survival, proliferation, and apoptosis resistance was already established both in vitro and in vivo , much less was done in the studying of the downstream pathways where TRPV6 channel is involved which are restricted so far to the Ca2+ - calmodulin – calcineurin – NFaT pathways. Finally, in addition to the establishment of its role in human pathophysiology, the first pharmacological approaches were undertaken to target this channel and are described here in detail.
