lactis were shown to mitigate gut inflammation in mice by reducing the macroscopic and microscopic symptoms of DSS-induced colitis, diminishing weight loss, improving survival, and modulating the production of cytokines TGF-β, IL-6, and IL-12 in the colon, and TGF-β and IL-6 in the spleen with expansion of CD4+FOXP3+ regulatory T cells in the cecal lymphnodes [4]. Here, TGFB1 is linked to colitis.
