GDNF expressions (stained by immunohistochemistry) in the multiple brain regions in the asthmatic rats. Red box indicated the areas of positive immunoreactive cells. (A) GDNF expressions in MeA; (B) GDNF expressions in cortex; (C) GDNF expressions in PVN; (D) GDNF expressions in NTS. GDNF positive immunoreactive substances were brownish-yellow staining. GDNF, glial cell line-derived neurotrophic factor; MeA, medial amygdala; PVN, paraventricular nucleus; 3V, third ventricle; CC, central canal; NTS, nucleus of solitary tract.
