In Vivo Delta Opioid Receptor Internalization Controls Behavioral Effects of Agonists
Figure 1
Delta agonists differentially internalize DOR-eGFP in primary neurons.
Striatal and hippocampal primary neurons were treated for 60 minutes with Met-enkephalin, SNC80 or ARM390. (A) Representative images of hippocampal neurons treated with 100 nM of agonists are shown. Scale bar is 12 µm. (B) Internalized DOR-eGFP co-localized with lysosomes. Striatal primary neurons were incubated with Met-enkephalin (100 nM) or SNC80 (100 nM) for 20 or 120 minutes, along with LysoTracker Red DND 99 (300 nM); scale bar is 12 µm.
