serotonin receptor subtypes

Serotonin receptor subtypes are different types of proteins on cells that respond to the chemical serotonin, which influences mood, sleep, appetite, and other functions. There are many subtypes, like 5-HT1, 5-HT2, 5-HT3, etc., each with unique roles and locations in the body and brain. For example, some help regulate anxiety and depression, while others affect nausea or blood vessel constriction. Understanding these subtypes helps develop medications that target specific receptors to treat conditions like depression, migraines, or schizophrenia more effectively and with fewer side effects.
