The receptor NLRP3 is a transcriptional regulator of TH2 differentiation.
2015
The receptor NLRP3 is involved in the formation of the NLRP3 inflammasome that activates caspase-1 and mediates the release of interleukin 1β (IL-1β) and IL-18. Whether NLRP3 can shape immunological function independently of inflammasomes is unclear. We found that NLRP3 expression in CD4(+) T cells specifically supported a T helper type 2 (TH2) transcriptional program in a cell-intrinsic manner. NLRP3, but not the inflammasome adaptor ASC or caspase-1, positively regulated a TH2 program. In TH2 cells, NLRP3 bound the Il4 promoter and transactivated it in conjunction with the transcription factor IRF4. Nlrp3-deficient TH2 cells supported melanoma tumor growth in an IL-4-dependent manner and …
Étude de la régulation transcriptionnelle des lymphocytes Th9
2017
CD4 helper T cells support a wide range of functions due to their ability to differentiate into different effector subsets depending on the antigen encountered and the cytokine environment in which they are. Current knowledge on the differentiation of helper T cells highlights the existence of complex transcriptional networks specific to each T helper subset. In 2008, IL-9 secreting CD4 T cells (Th9) are identified as a new helper T cell subtype. Differentiated in the presence of IL-4 and TGF-β, Th9 cells secrete IL-9 and IL-21, and contribute to the development of autoimmune and allergic diseases. Th9 lymphocytes also exhibit strong anti-tumor properties.The transcriptional network of the …
