The stability and plasticity of Tfh cells in vivo. (A) Experimental design for testing Tfh stability in vivo. (B) The sorted effector Tfh and non-Tfh (CD45.2+) cells were adoptively transferred into congenic recipient mice (CD45.1+). 7 d after s.c. immunization with KLH in IFA, the expression of CXCR5 and Bcl6 in donor Tfh and non-Tfh cells was measured by flow cytometry. Data are representative of two independent experiments. Bar graphs display the number of donor cells as mean ± SD. n = 3 per group.
