Andrographolide Inhibition of Th17-Regulated Cytokines and JAK1/STAT3 Signaling in OVA-Stimulated Asthma in Mice

Figure 3

AG inhibited JAK1-STAT3 activation and the expression of transcription factor in OVA-stimulated asthmatic mice. As shown in Figure 3, OVA (0.1 μg/μL) treatment induced JAK1 and STAT3 phosphorylation, which were abated by AG in the dosage of 0.1 mg/ml (). Furthermore, the expression of the downstream transcription factor RORγt was also inhibited by AG in OVA-induced asthmatic mice (). The values are expressed as the mean ± the standard deviation of triplicate tests. relative to the control group; , relative to the OVA group.
