T cells robustly respond to virus infection. Egr-2 and -3 are induced in both naïve and tolerant T cells (PMC2652694, PMID15585857, PMID15834410). The deficiency of Egr-2 and -3 specifically in B and T cells results in autoimmunity (PMID23021953). It is however unknown whether they also play roles in protective immmunoresponses.
