      The D1-like subfamily comprises D1- and D5-R, while the D2-like includes D2-, D3- and D4-R. D1 receptors are coupled to stimulatory G proteins, and the D2 subtype to inhibitory Gi/Go proteins.

      To further understand the basis of these behavioral differences, this study aimed to determine if the sensitivity of D1 and D2 dopamine receptors changes with age. To do so, I administered direct D1 (SKF 83822) and D2 (quinpirole) agonists to adult and adolescent rats and then measured locomotor and stereotypic behaviors.

      FIG. 1. Dopamine receptor structure. Structural features of D1-like receptors are represented. D2-like receptors are characterized by a shorter COOH-terminal tail and by a bigger 3rd intracellular loop. Residues involved in dopamine binding are highlighted in transmembrane domains.

      [[ 1 ]] Actions of Dopamine. Dopamine activates α & β . and D1 & D2- dopamine receptors. (1) Cardiovascular: Dopamine exerts a stimulatory effect on the β1 receptors of the heart, having both inotropic and chronotropic effects (Figure 6.12). At very high doses, dopamine activates α-receptors on the . vasculature, resulting in vasoconstriction.

      D1 receptors expressed in regions such as the Nucleus Accumbens elicit an excitatory response through the activation of adenylyl cyclase, while D2 receptors in the same regions inhibit adenylyl cyclase; an abundance of dopamine leads to D1 activation, while less dopamine saturation activates D2 receptors (Trantham-Davidson, 2004).

      Modulation of cortical function can be achieved via the D1, D2, D3 and D4 dopamine receptors, leading to the "fine tuning" of information processing. D1 and D2 are high in the striatum, D3 is located in the nucleus accumbens and D4 is high in the frontal cortex and limbic areas.

      The D2 family includes D2, D3, and D5 dopamine receptors. The D1 family is excitatory. It is coupled to a Gs stimulatory protein that subsequently activates adenylyl cyclase. The D2 family is inhibitory. It is coupled to a Gi inhibitory protein that subsequently inhibits adenylyl cyclase [6]. The study of dopamine’s influence on neurons in ...
