Caffeic acid phenethyl ester modifies the Th1/Th2 balance in ileal mucosa after γ-irradiation in the rat by modulating the cytokine pattern

Figure 1 Th1/Th2-like pattern of gene expression in the ileal mucosal layer after γ-irradiation in rats. (■): CAPE-untreated, (□): CAPE-treated and CD4⁺ immunostaining in control (C), 6 h and 7 d (D7) after irradiation (D (x 20) (mean ± SEM, n = 6); ^aP < 0.05, ^bP < 0.01 vs control; ^cP < 0.05, ^dP < 0.001 vs untreated.
