5-HT1 receptor

The 5-HT1 receptor (pronounced as "five H T one receptor"), also known as the serotonin 1 receptor, is a subtype of serotonin receptor that binds the neurotransmitter serotonin, also known as 5-hydroxytryptamine (5-HT).

Etymology

The term "5-HT1 receptor" is derived from the chemical name for serotonin, 5-hydroxytryptamine, and the number 1 denotes it as a subtype of serotonin receptors.

Function

The 5-HT1 receptor is involved in a variety of physiological and neurological processes, which can include the regulation of mood, anxiety, sleep, and appetite. It is also implicated in the pathophysiology of several disorders, including depression, migraine, and schizophrenia.

Subtypes

There are several subtypes of the 5-HT1 receptor, including 5-HT1A, 5-HT1B, 5-HT1D, 5-HT1E, and 5-HT1F. Each subtype has a different distribution within the brain and plays a different role in the body's response to serotonin.
