Abstract: The present invention relates to regulatory T cell and uses thereof. By their immunosuppressive and anti-inflammatory activities, regulatory T cells play a central role in peripheral tolerance and thus critically prevent the development of autoimmune and inflammatory disorders. The inventors showed that Foxp3+CD4+ Tregs express high levels of LT?, which negatively regulates their immunosuppressive signature. They demonstrated that the adoptive transfer of LT??/? Tregs in mice protects from dextran sodium sulfate (DSS)-induced colitis and attenuates inflammatory bowel disease (IBD), multi-organ autoimmunity and the development of CAC. The inventors also showed that by mixed bone marrow chimeras that LT? expression specifically in hematopoietic cells negatively controls the immunosuppressive signature of Tregs. In particular, the present invention relates to regulatory T cell characterized in that it does not express or expresses reduced levels of lymphotoxin alpha.

Abstract: Sarcomas are rare malignant tumors arising from the mesenchymal tissues at all body sites. The inventors show that in a mouse model of p16/p19 deficiency prone to tumor development, the absence of the mouse pantetheinase Vnn1 enhances the frequency of aggressive fibrosarcomas. They also show that reintroduction of a catalytically active form of the Vnn1 pantetheinase limits tumor growth in vivo. Interestingly, VNN1 expression in human sarcomas is associated with reduced aggressiveness and lower risk of metastatic relapse in patients. In conclusion, Vnn1 represents a novel marker of sarcoma and may modulate tumor aggressiveness by sustaining myofibroblast cell differentiation, thereby limiting evolution towards undifferentiated tumors. The present invention relates to the use of Vnn1 as a biomarker and a therapeutic target in sarcomas.
