High-affinity B cell selection in the germinal center (GC) is governed by signals delivered by follicular helper T (Tfh) cells to B cells. Selected B cells undergo clonal expansion and affinity maturation in the GC dark zone in direct proportion to the amount of antigen they capture and present to Tfh cells in the light zone. Here, we examined the mechanisms whereby Tfh cells program the number of GC B cell divisions. Gene expression analysis revealed that Tfh cells induce Myc expression in ligh ...[more]
