Figure 3. Tfh cells are recruited to the liver in infected mice.

Five weeks after S. japonicum infection, ICOSL KO mice were received the PBS, eGFP⁺ Tfh cells or eGFP⁺ non-Tfh cells as described in Materials and Methods. (A) Flow cytometric pseudocolor plots of eGFP⁺ cells from normal and infected mice recipients 3 days after adoptive transfer of the PBS, eGFP⁺ Tfh or eGFP⁺ non-Tfh cells. The numbers in the plots represent percentages; (B) Representative of liver slices from normal and infected mice recipients 3 days after adoptive transfer. Original magnification, ×400.
