Full textSickle cell disease (SCD) is a genetic disorder marked by recurrent vaso-occlusive crises and progressive multi-organ damage, including kidney disease and muscle wasting, both of which worsen morbidity and reduce quality of life of affected patients. While the mechanisms underlying SCD-related kidney disease are well-established, the drivers of muscle atrophy remain incompletely understood. Emerging evidence suggests that Activin A, a member of the TGF-β superfamily, plays a significant role in both fibrosis and disease progression in kidney disease as well as muscle atrophy. However, its role in SCD-associated muscle and kidney damage has yet to be elucidated. This study investigates the role of Activin A in SCD-associated muscle wasting and kidney disease. We assessed sarcopenia prevalence and circulating Activin A levels in SCD patients and employed a murine model to analyse the temporal changes in muscle and kidney pathology as well as the involvement of Activin pathway in these pathologies. Our findings confirm that sarcopenia is prevalent among SCD patients, emphasizing the need for focused research on SCD muscle pathology. Both patient and murine models showed elevated Activin A levels in SCD, supporting the hypothesis that Activin A may contribute to kidney disease and muscle atrophy in this context. In SCD mice, ultrastructural alterations, myofiber atrophy, reduced vascularization, and impaired muscle stem cells preceded detectable kidney pathology. Pharmacological inhibition of Activin signalling pathway mitigated muscle damage and showed early signs of kidney improvement, suggesting it as a promising therapeutic target for SCD complications and patient outcomes enhancement

Full textThe Epstein-Barr virus is associated to different human lymphoid or epithelial tumour pathologies. The BNLF1 gene is considered as the main viral oncogene and encodes the LMP1 which displays numerous activities: induction of various signalling pathways (like the NF-kB pathway) but also blocking of cell division or protein synthesis. In this thesis, we have described a new property of LMP1 and shown that it very efficiently inhibits the activity of several natural complex promoters, of viral or cellular origin. We have also described a new LMP1 isoform, In89LMP1, and shown that it was able to inhibit the activity of the full length LMP1 on the NF-kB pathway. Thus, we have identified two novel retrocontrol mechanisms acting on LMP1, that could be required for long term survival of LMP1 expressing cells

Full textOne of the most striking effects of ageing is an involuntary loss of skeletal muscle mass known as sarcopenia. The development of sarcopenia appears to be multifactorial and includes anabolic resistance to dietary amino acids and sedentary lifestyle. The diminished ability of aged muscle to self-repair is also a key factor of sarcopenia. During the regeneration process, immune and muscle cells work in a cross-talk leading to an optimal muscle cell proliferation and differentiation. However, with aging, the immune response is impaired, possibly contributing to the reduction in the capacity of regeneration.Muscle and immune cells are both targets of vitamin D action. This vitamin modulates muscle cell proliferation and differentiation and stimulates the anti-inflammatory response of immune cells. With age, vitamin D insufficiencies or deficiencies develop.In this context, the main objective of this thesis was to evaluate the regulatory action of vitamin D on the cross-talk between immune and muscle cells and its implication in the ability of skeletl muscle to regenerate during aging.Initially, we studied in vitro the differentiation of L6 muscle cells co-cultured with or without immune cells (PBMC: peripheral blood mononuclear cells), and in with or without of LPS. From this model, PBMC stimulated muscle cell differentiation. The pro-inflammatory response induced by LPS inhibited the expression of muscle differentiation markers in muscle cells. Of note, these markers were stimulated even in presence of LPS. In addition, the LPS-associated pro-inflammatory environment inhibited the Notch signaling pathway, the key pathway of muscle regeneration process, in L6 cells co-cultured with PBMC. We then used the same system of co-cultures to determine whether vitamin D, in its 25 (OH)D form, could modulate PBMC cytokine secretion and thereby could alter the expression of markers of muscle differentiation. Unfortunately, the treatment of co-culture with 25 (OH) D has changed neither the profile of PBMC cytokine secretion nor the expression of differentiation markers in L6 cells.Secondly, we investigated in a model of old rats the mechanisms that contribute to muscle atrophy following vitamin D depletion. We have demonstrated that the activity of the Notch signaling pathway, as well as muscle proliferation were reduced in old vitamin D-depleted rats, even in the absence of lesions. Then we evaluated the effect of the vitamin D status on an acute muscle regeneration process, i.e. muscle infusion of notexin in old rats. This ongoing experiment has already highlighted that during aging, muscle proliferation is reduced after injury, especially if age is associated with a vitamin D deficiency. In addition, during aging, the expression of differentiation markers was altered resulting in delayed and/or incomplete differentiation process, in particular in vitamin D-depleted old rats. However, vitamin D supplementation seemed to have no beneficial or deleterious effects on muscle regeneration in aged rats.In conclusion, in vitro 25 (OH) D was unable to modulate the differentiation of muscle cells co-cultured with immune cells. However, in vivo, vitamin D depletion appeared to worse the effect of ageing on muscle regeneration.The diminished ability of aged muscle to self-repair is a factor of sarcopenia. Our work has demonstrated the importance of maintening optimal vitamin D status to preserve muscle regeneration capacity and thus to limit muscle atrophy during aging
