Butyrate Produced by Gut Microbiome Can Improve Antitumor Responses of T Cells
- Studies have shown that gut microbiota can regulate tumor responsiveness to chemotherapy or immunotherapy.
- However, the mechanism of this regulation is not clear.
- Researchers found that metabolites from gut microbiota can increase the effectiveness of oxaliplatin by regulating CD8+ T cell function in the tumor microenvironment.
- Oxaliplatin is a drug used to treat colon and rectal cancer.
- Butyrate is one of the metabolites produced by the gut microbiota.
- Butyrate treatment improved the antitumor responses of cytotoxic CD8+ T cell by promoting the IL-12 signaling pathway.
- IL-12 signaling pathway is associated with the activation of innate and adaptive immune responses.
- Cancer patients that responded to oxaliplatin showed higher level of serum butyrate.
- High level of serum butyrate can improve ID2 expression and CD8+ T cell function.
- The results suggest that butyrate produced by gut microbiota can improve antitumor responses of CD8+ T cells.
