Describe the synthesis of dopamine and diagram the postsynaptic dopamine receptor subtypes. Identify the most common dopamine agonists and antagonists and describe their mechanisms of action
What will be an ideal response?
Answer: DA is synthesized from tyrosine and then L-DOPA. Dopamine acts via 2 families of receptors: the D1 and D2 receptors. D1 receptors are postsynaptic and linked to increased cyclic AMP, whereas D2 receptors are found pre- and postsynaptically and are negatively coupled to cyclic AMP. DA autoreceptors inhibit the presynaptic cell.
