Tph1 serotonin
SpletHere, we report that serotonin regulates β-cell proliferation through serotonin receptor 2B (HTR2B) in an autocrine/ paracrine manner during the perinatal period. In β-cell-specific Tph1 knockout (Tph1 bKO) mice, perinatal β-cell proliferation was reduced along with the loss of serotonin production in β-cells.

Tryptophan hydroxylase 1 (TPH1) is an isoenzyme of tryptophan hydroxylase which in humans is encoded by the TPH1 gene. TPH1 was first discovered to synthesize serotonin in 1988 and was thought that there only was a single TPH gene until 2003, while a second form was found in the mouse (Tph2), rat and … Prikaži več Tryptophan hydroxylases catalyze the biopterin-dependent monooxygenation of tryptophan to 5-hydroxytryptophan (5-HTP), which is subsequently decarboxylated to form the neurotransmitter serotonin (5-hydroxytryptamine … Prikaži več Tryptophan hydroxylase is important for synthesizing indoleamine neurotransmitters and related compounds in the body and brain, including serotonin and Prikaži več • Li D, He L (2007).

Splet21. mar. 2024 · Specialized enterochromaffin (EC) cells within the mucosal lining of the gut synthesize and secrete almost all serotonin (5-hydroxytryptamine, 5-HT) in the body. Significantly lower amounts of 5-HT are made by other peripheral tissues and serotonergic neurons within the enteric nervous system (ENS).

In vertebrates it exists in two isoforms, TPH1 and TPH2. TPH1 is mainly synthesized by enterochromaffin cells in the gut, whereas TPH2 is produced by serotonergic neurons in the central nervous system and by enteric neurons in the gut.
Splet01. jan. 2024 · Serotonin (5-hydroxytryptamine [5-HT]) is synthesized mainly within enterochromaffin (EC) cells in the gut, and tryptophan hydroxylase 1 (Tph1) is the rate-limiting enzyme for 5-HT synthesis in EC cells. ...
