Figure 5: Localization of IL-4 and GR in the LC. (a–c) Representative fluorescent images showed that IL-4 (a) and GR (b) were expressed in the neurons but not in the identical part (c). Photomicrographs were taken at ×200 magnification. Scale bars = 50 μm. (d–f) High power (taken at ×400 magnification) photographs of (a), (b), and (c), respectively, are shown. Scale bars = 20 μm.
