GRPEL1 and infection: Evaluation of cervical tissue sections 21 days after infection by S-P immunohistochemistry showed that the mice immunized with recombinant GrpE protein presented nearly normal cervical tissue compared with control group (Figures 8D,H) and fewer inflammatory cells in the cervical tissue (Figures 8C,G), compared to the FA- (Figures 8B,F) and PBS- (Figures 8A,E) immunized mice.
