Red wine extract disrupts Th17 lymphocyte differentiation in a colorectal cancer context
2020
International audience; Scope: Scope: It is well established that immune response and inflammation promote tumoral progression. Immune cells communicate through direct contact or through cytokine secretion, and it is the pro-inflammatory status that will tip the balance toward tumor progression or anti-tumor immunity. It is demonstrated here that a red wine extract (RWE) can decrease inflammation through its action on the inflammasome complex. This study determines whether an RWE could impact other key actors of inflammation, including T helper 17 (Th17) immune cells in particular. Methods and results: Methods and results: Using an RWE containing 4.16 g of polyphenols/liter of wine, it is s…
Identification of non-canonical NLRP3 functions in Th17 cells - Therapeutic interest to promote antitumor immune response
2021
Since decades, cancers have become a major public health issue, occupying the first premature mortality cause in France. One of the hallmarks of cancer cells is their ability to escape the immune system surveillance, notably through setting up an immunosuppressive environment within the tumor. The NLRP3 protein is largely studied in the inflammasome context, which is assembled in order to promote inflammation through IL-1β secretion. However, this protein also functions as a transcription factor in CD4+ T cells. Indeed, in Th2 cells, NLRP3 cooperate together with IRF4, to form a complex that is able to activate the transcription of Il4, Il5 and Il13, which are necessary for the function of …
