The effects of serotonin by Tph1 and Htr2b on skeletal muscle


ABSTRACT: It is known that reducing circulating serotonin by inhibiting Tph1 increases the sensitivity of BAT cells and this drives thermogenesis by fat and glucose oxidation. In our results inhibiting Tph1 in muscle showed activation of SIRT1/LKB1/AMPK pathway in skeletal muscle cells and increased p-ACC. Also, it's known that inhibiting adipose Htr2b signaling ameliorates HFD-induced systemic insulin resistance. Here we report insulin sensitivity changes by regulating serotonin in skeletal muscle by Htr2b. Inhibiting Htr2b increases AMPK activity, glucose uptake, and myofiber size and decreases lipid droplet accumulation in HFD mice skeletal muscle. These results indicate improved insulin resistance and myosteatosis in skeletal muscle by lack of Serotonin by Tph1/Htr2b on skeletal muscle.
