The levels of CD206 staining were significantly lower in the corilagin groups compared with the model infection groups (p < 0.05, Student's t-test, n = 6), and the area decreased with increasing concentrations of corilagin (p < 0.05, one-way ANOVA, post-hoc: S-N-K method, n = 6). Here, MRC1 is linked to infection.
