MC3R Expression in the VTA:

A cholera toxin B (CTB)-based retrograde tracing strategy was used to study whether Arc POMC neurons projected to the VTA. To label perikarya of neurons in the Arc nucleus projecting to the VTA, the rats (n=6) were treated with CTB (0.5% solution; #103, List Biological Laboratories, Campbell, CA) via unilateral iontophoresis (5A, 7s onoff) into the VTA for 20min.
