5 Ht2A Neurons is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
Neurons expressing the serotonin 2A receptor (HTR2A) represent a crucial component of the serotonergic system in the brain. HTR2A is a Gq-coupled GPCR that mediates the effects of serotonin on pyramidal neurons, particularly in the prefrontal cortex. This receptor is of paramount importance in psychiatric pharmacology, being the target of atypical antipsychotics and psychedelic compounds, and is increasingly implicated in neurodegenerative disease processes.

Location
HTR2A-expressing neurons are predominantly found in: [@serotonin2022]
Prefrontal Cortex: Layer V pyramidal neurons, especially in dorsolateral and medial PFC
Anterior Cingulate Cortex: Involved in cognitive control and decision-making
