Previously, we reported that chemokine (C-C motif) receptor 2 (CCR2) heteromerizes with α1B-adrenoceptor (α1B-AR) in leukocytes, through which α1B-AR controls CCR2. Whether such heteromers are expressed in human vascular smooth muscle cells (hVSMCs) is unknown. Bioluminescence resonance energy transfer confirmed formation of recombinant CCR2:α1b-AR heteromers. Proximity ligation assays detected CCR2:α1B-AR heteromers in hVSMCs and human mesenteric arteries. CCR2:α1B-AR heteromerization per se enhanced α1B-AR-mediated Gαq-coupling. Chemokine (C-C motif) ligand 2 (CCL2) binding to CCR2 inhibited Gαq activation via α1B-AR, cross-recruited β-arrestin to and induced internalization of α1B-AR in recombinant systems and in hVSMCs. Our findings suggest that CCR2 within CCR2:α1B-AR heteromers biases α1B-AR signaling and provide a mechanism for previous observations suggesting a role for CCL2/CCR2 in the regulation of cardiovascular function.
