Morphine promotes rapid, arrestin-dependent endocytosis of mu-opioid receptors in striatal neurons

Morphine activates mu-opioid receptors (MORs) without promoting their rapid endocytosis in a number of cell types. A previous study suggested that morphine can drive rapid redistribution of MORs in the nucleus accumbens, but it was not possible in this in vivo study to identify a specific membrane t...
