SAA significantly affected permeability between intestinal epithelium cells through PPs activation. (A) A (A₁) and P_app (A₂) values of Flu permeation in isolated intestinal tissues with SAA incubated PPs or PPs_IP. (B) Representative fluorescent images of TJ proteins (red) in intestinal villi (B₁) and the quantitative analyses of the IOD (B₂), with nuclei stained by DAPI (blue). Original magnification × 200. The data are expressed as mean ± SD (n = 5). *P < 0.05, ^**P < 0.01 and ^***P < 0.001 vs BC group with PPs participation; ^#P < 0.05, ^##P < 0.01 and ^###P < 0.001 vs BC group with PPs_IP participation; ^&P < 0.05, ^&&P < 0.01 and ^&&&P < 0.001 vs PPs group at the same time point.
