TLR2 and type 2 diabetes mellitus: Therefore, scientists have explored the underlying mechanism of Amuc_1100 functions, such as the activation of AhR (Gu et al., 2021), Toll-like receptor 2 (TLR2), and TLR4 (Plovier et al., 2017; Ottman et al., 2017b; Wang et al., 2021), reduction of colonic cytotoxic T lymphocytes (Wang et al., 2020), and inhibition of lipid synthesis and transport genes (Zhang F. L. et al., 2021), thereby alleviating T2D and related diseases.
