Figure 5. Andrographolide inhibited NLRP3 inflammasome activation in mice with OVA-induced asthma.
A. Lung tissue protein was extracted from the treated mice and protein levels of CASP1, NLRP3 and ASC were examined by western blot. B. Paraffin-embedded lung tissue sections each group were immunostained with DAPI (blue) and anti-CD11b-FITC (green) and observed by fluorescence microscopy, ×100. Scale bar 50 μm.
