Cellular localization of mGluR1 and mGluR5 in rat and human adrenal medulla. (A,C) Double immunofluorescence staining of mGluR1 (green) with tyrosine hydroxylase (TH) (red) in rat and human adrenal medulla (a–c1,g–i1). TH-labeled catecholaminergic cells. (B,D) Double immunofluorescence staining of mGluR1 (green) with neurofilament (NF) (red) in rat and human adrenal medulla (d–f1,j–l1). NF-labeled nerve fibers and neurons. (E,G) Double immunofluorescence staining of mGluR5 (green) with TH (red) in rat and human adrenal medulla (m–o1,s–u1). (F,H) Double immunofluorescence staining of mGluR5 (green) with NF (red) in rat and human adrenal medulla (p–r1,v–x1). Higher magnification images of framed areas are shown in matched lower panels. Scale bar = 25 μm.
