Dopamine (DA) is a key neurotransmitter regulating movement, cognition, and homeostasis. This review details DA receptors and their therapeutic roles in Parkinson's disease, schizophrenia, and hypertension.

Area of Science:

  • Neuroscience
  • Pharmacology
  • Molecular Biology

Background:

  • Dopamine (DA) is a crucial neurotransmitter and neuromodulator.
  • DA influences central nervous system functions like locomotion, cognition, and emotion.
  • Peripherally, DA regulates homeostasis, vascular tone, and hormone secretion.

Purpose of the Study:

  • To summarize current knowledge on dopamine receptors.
  • To detail their molecular and pharmacological characteristics.
  • To review their physiological roles and therapeutic applications.

Main Methods:

  • Literature review of dopamine receptor research.
  • Analysis of molecular and pharmacological data.
  • Synthesis of information on physiological functions and disease involvement.

Main Results:

  • Dopamine exerts diverse functions via five distinct G-protein-coupled receptors (D1-D5).
  • Receptors are classified into D1 (D1, D5) and D2 (D2, D3, D4) families.
  • Dopamine receptor signaling is implicated in neurological and cardiovascular disorders.

Conclusions:

  • Dopamine receptors are vital targets for understanding physiological processes.
  • Pharmacological characterization of these receptors is essential for therapeutic development.
  • Dopamine receptor modulation is key in treating Parkinson's disease, schizophrenia, and hypertension.
