FIGURE 3.
Distribution of mGluR1 in rat CB. Panels (A–C) are double immunofluorescence staining of mGluR1 (green) with TH (red) in rat CB. Panels (D–F) are double immunofluorescence staining of mGluR1 (green) and GFAP (red) in rat CB. Some TH-immunoreactive type I cells are immunoreactive for mGluR1 (arrows), whereas the GFAP-immunoreactive type II cells are not immunoreactive for mGluR1 (arrowheads). TH, tyrosine hydroxylase, the CB type I cells marker; GFAP, glial fibrillary acidic protein, the CB type II cells marker; mGluR, glutamate metabotropic receptor. Scale bar, 10 μm for all images.
