> What is the role of D3 receptors in depression?D3 receptors occur in limbic structures such as the nucleus accumbens, a region that mediates reward, pleasure, and drive. Dysfunction here is thought to be responsible for anhedonia.
"and a D2/D3 dopamine receptor agonist exhibits antidepressant-like effects in numerous depression models including learned helplessness paradigm and chronic mild stress model [104]. Moreover, it has been reported that stimulation of D2/3 dopamine receptors, but not of the D4 dopamine receptor, exhibits an antidepressant-like effect in the forced swimming test [12]"

DBS in the nucleus accumbens reduces depression.
"We demonstrate antidepressant and antianhedonic effects of DBS to NAcc in patients suffering from TRD."

I tried Fanapt (iloperidone), but I didn't like it for some reason. I don't remember why. Looking at its binding profile, I see that Fanapt acts like prazosin at the NE alpha-1 receptor. Interesting.
