Role of 5-HT2A, 5-HT2C, 5-HT1A and TAAR1 receptors in the head twitch response induced by 5-hydroxytryptophan and psilocybin: Translational implications

Abstract: There is increasing interest in the therapeutic potential of psilocybin in psychiatric disorders. In common with other serotonergic psychedelics, psilocybin is thought to act via the 5-HT2A receptor (5-HT2AR). Serotonin is the endogenous ligand of 5-HTR. In rodents, the serotonin precursor, 5-hydroxytryptophan (5-HTP), and psilocybin, induce a characteristic head twitch response (HTR), which is correlated with the human psychedelic trip in intensity and duration. We examined the role of other serotonergic rece… Show more
