Abstract excerpt
Pathogen-induced memory Tfh cells are important to maintain high-affinity antibodies against pathogens. We have now discovered Tfh cells with a similar memory phenotype (MP) that develop in pathogen-free conditions. These MP Tfh cells are similar to pathogen-induced memory Tfh in both phenotype and function. They express FR4 and Egr2, which are both found in pathogen-induced memory Tfh cells. FR4+Egr2+ CD4 MP...
