Abstract

Two classes of dopamine receptor mechanism are defined according to their association with, or independence from, a dopamine-sensitive adenylyl cyclase. Dopamine receptors unrelated to adenylyl cyclase are designated type alpha. Dopamine receptors linked to adenylyl cyclase are designated type beta. Drugs discriminate between the two receptor mechanisms. The dopaminergic ergots (lisuride, lergotrile and CB-154) and their antagonists (such as metoclopramide) are relatively specific for the alpha-dopaminergic receptor in the anterior pituitary. Other agonists (e.g. apomorphine and dopamine) and antagonists (e.g. antipsychotic phenothiazines and butyrophenones) affect both classes of receptor.

      On the basis of their structural, pharmacological and biochemical properties, DRs are classified as D1-like (D1 and D5) and D2-like (D2, D3 and D4) (Beaulieu and Gainetdinov, 2011). D2-like DRs are coupled to Gαi/o proteins and inhibit the production of the second messenger cyclic adenosine monophosphate (cAMP) through the inhibition of adenylate cyclase (AC), which leads to decreased protein kinase A (PKA) activity (Beaulieu et al., 2015; Kebabian, 1978). Clinically, D2-like DRs are important therapeutic targets for antiparkinsonian (agonists) and antipsychotic (antagonists or partial agonists) drugs, especially D2 that is the common target for all approved antipsychotic drugs so far (Arnsten et al., 2017; Silva et al., 2020).

      When DRs modulators bind to their specific receptors, they promote downstream coupling of the heterotrimeric G proteins Gα-s/olf or Gα-i/o, which are stimulatory and inhibitory receptors, respectively. The functional state of the second messenger such as cyclic adenosine monophosphate (cAMP) depends on the type of DRs being coupled [79,80]. It was found that D1 class receptors activate Gα-s/olf, stimulate adenylate cyclase (AC), and increase cAMP levels.

      Dopamine exerts its physiological effects through the two subtypes of receptors i.e. the D1-family (D1R and D5R) and the D2-family (D2R, D3R, and D4R) receptors which vary in their distribution, affinity, and signaling pattern [3]. The D1-like subfamily (D1R and D5R) are coupled to Gαs/olf proteins to activate adenylyl cyclase (AC) whereas the D2-like receptors are coupled to Gαi/o subunits and suppress the activity of AC [3,4]. Besides, there are D2RS (D2R-short) and D2RL (D2R-long) variants of the D2R, due to the alternative splicing, that are related to presynaptic and postsynaptic neuronal populations, respectively.

      Physiological functions of DA are mainly mediated by DA receptors. DA receptor, an important G protein-coupled receptor (GPCR), is classified into two families: the D1-like (D1 and D5) and D2-like (D2, D3 and D4) receptor families, according to their downstream signaling pathways [11,12]. A previous study demonstrated that lower expression of D2R increased the expression of profibrotic factors, such as TGF-β1, and the production of ECM proteins in human renal proximal tubule cells [13].

      There are 5 major subtypes of DRs that belong to a superfamily of metabotropic G-protein-coupled receptors of seven A-class transmembrane domains (Harmar et al., 2009), divided into two families according to their pharmacological profile. The D1-like receptor subtypes (D1R and D5R) are stimulatory receptors coupled to the Gαs-protein and the D2-like receptor subtypes (D2R, D3R and D4R) are inhibitory receptors coupled to the Gαi/o-protein, depending on their ability to subsequently activate the enzyme adenylyl cyclase, increasing or not the intracellular concentration of the secondary messenger cyclic adenosine monophosphate (cAMP), respectively (Kebabian, 1978; Beaulieu et al., 2015; Spano et al., 1978). Interestingly, DRs can form heterodimers leading to a particularly organized, varying combinatorial possibilities at a higher level, which gives this family of receptors very diverse pharmacological and functional properties (Beaulieu et al., 2015).
