Characterization of mice lacking the CB1 receptor in dbh expressing cells. (A) qPCR analysis of CB1/dbh ratio mRNA levels in the superior cervical ganglia (n = 5). (B) qPCR analysis of CB1/dbh ratio mRNA levels in brain punches (0.5 mm diameter) from the locus ceruleus brain region with surrounding tissues. Data are mean ± SE of n = 3–4 samples. (C) Double fluorescent in situ hybridization in locus ceruleus. Green: CB1 receptor, Red: DBH, Blue: DAPI. Scale bar = 50 μm. For (A,B), Student t-test; ** p ≤ 0.01, *** p ≤ 0.001.
