5-HT Receptors: Roles, Functions, and Their Connection to Depression

5-HT receptors, also known as serotonin receptors, are a diverse family of receptors that bind to serotonin, a key neurotransmitter in the brain. Serotonin, or 5-hydroxytryptamine (5-HT), plays a crucial role in regulating mood, emotion, and various physiological processes. The 5-HT receptor family is classified into several subtypes, each with distinct functions and distributions in the central nervous system (CNS) and peripheral tissues.
