          Hormone Serotonin or 5-hydroxytryptamine (5-HT) 

Serotonin or 5-hydroxytryptamine (5-HT) is a monoamine neurotransmitter derived from tryptophan, primarily found in the gastrointestinal (GI) tract, platelets, and in the central nervous system (CNS). In Gut, serotonin regulates intestinal movements, in CNS, it regulates mood, appetite, sleep, memory and learning, etc.

     Hormone Serotonin or 5-hydroxytryptamine (5-HT): Serotonin and insulin resistance 

In the study to assess the effect of 5-HT on insulin-mediated glucose uptake, showed that the effects of 5-HT on insulin-mediated glucose uptake were partially reversed by vasodilation with carbachol. In contrast to the results for the hindlimb, 10 microM 5-HT had no significant effect on either basal glucose uptake or the stimulation of glucose uptake mediated by 15 nM insulin by isolated incubated soleus or extensor digitorum longus muscles. It is concluded that 5-HT impairs insulin-mediated glucose uptake in the perfused rat hindlimb that may derive from vascular shunting not apparent when muscles are incubated with 5-HT in vitro(39).
