A REVIEW ON FUNCTIONAL COMPARISON OF 5-HT1A AND 5-HT2C RECEPTORS

5-HT neurotransmission system is targeted by drugs useful in behavioural disorders, including anxiety, depression, psychosis and eating disorders. 5-HT1A autoreceptors, located on 5-HT neurones of the midbrain raphe nuclei, are coupled to K channels through a pertusis toxin-sensitive G-protein. 5-HT1A receptor agonists inhibit adenylyl cyclase, while 5-HT2C receptor agonists activate two signal transduction pathways coupled with these receptors. 5-HT1A and 5-HT2C receptors have lots potential in treating the disorders with less or no side effects. Keywords: 5-HT1A, 5-HT2C, Receptor.
