5-HT2A

Meaning

The 5-HT2A receptor is a specific subtype of serotonin receptor, a G protein-coupled receptor found prominently in the central nervous system, particularly in the cerebral cortex. This receptor mediates many of the central actions of the neurotransmitter serotonin, influencing mood, cognition, and perception. Its function is integral to the intricate signaling network that governs psychological and physiological well-being, directly impacting hormonal regulation via its influence on the hypothalamic-pituitary axis.
