Current drug treatments targeting dopamine D3 receptor

Dopamine receptors (DR) have been extensively studied, but only in recent years they became object of investigation to elucidate the specific role of different subtypes (D1R, D2R, D3R, D4R, D5R) in neural transmission and circuitry. D1-like receptors (D1R and D5R) and D2-like receptors (D2R, D2R and D4R) differ in signal transduction, binding profile, localization in the central nervous system and physiological effects. D3R is involved in a...
