A, co‐localization of TH (red), GFAP (yellow) and LepRb‐EGFP (green) in the carotid bodies (CB) and superior cervical ganglion (SCG). Upper panel: 20, scale bar = 20 μm; lower panel, 40×, scale bar = 50 μm. B, percentage of type I (TH‐positive cells) and type II (GFAP‐positive cells) cells in the carotid bodies. C, percentage of type I and type II cells expressing LepRb (n = 5).
