Bile acids regulate MAdCAM-1 expression to link the gut microbiota to cancer immunosurveillance
Abstract
ABSTRACTIn a recent paper in Science, Fidelle et al. unravel a gut immune checkpoint that is subverted by antibiotic treatment. Post-antibiotic dysbiosis of the ileum causes an increase in bile acids that downregulate MAdCAM−1, thereby triggering the exodus of immunosuppressive T cells from gut-associated lymphoid tissues toward tumors.
