TPH1 & TPH2 Screening Services

Tryptophan hydroxylase 1 and 2 (Tph1/2) enzymes catalyze the monooxygentation of tryptophan to 5-hydroxytryptophan (5-HTP). Following monooxygentation, 5-HTP is decarboxylated and converted to serotonin. Through tryptophan depletion, TPH1 and TPH2 can inhibit immune system function in a manner similar to IDO1,2 and TDO. As tumor cells overexpress enzymes like Tph1/2, immune cells are deprived of essential amino acids and have impaired abilities to fight cancer.  

More specifically, TPH1 and TPH2 enzymes have been linked to many types of immune system regulation. In mice, Tph1 has been implicated in regulating tumor growth, the tolerance of transplanted tissues, inflammation, and autoimmunity. Additionally, excessive Tph1/2 activity results in depleted tryptophan and this causes reduced mTOR signaling. Tph1/2 can have a significant impact on the immune system and due to its diverse effects, it is a key drug target in immunotherapy.
