Blockade of Airway Inflammation by Kaempferol via Disturbing Tyk-STAT Signaling in Airway Epithelial Cells and in Asthmatic Mice
Figure 7
Immunohistochemical staining of phosphorylated STAT3 in lung tissues obtained from mice supplemented with 10–20 mg/kg kaempferol. Lung tissue sections were immunostained with a specific primary antibody against phosphorylated STAT3 and 3,3′-diaminobenzidine-conjugated IgG. Counter staining was conducted with hematoxylin. Phosphorylated STAT3 was identified as brown nuclear staining (a) and quantified by using an optical microscope system (b). Each photograph is representative of four mice. Magnification: 200-fold. Means without a common letter differ, .
