The finding that BCR-induced genes such as ITGAX and TNFRSF9 are enhanced in the latently infected T2 B cells suggests that the BCR-stimulated phenotype occurs in the latent as well as lytic cell populations, and that even in T2 LCLs only a relatively small portion of BCR-stimulated cells proceed to the fully lytic state of infection. The gene discussed is ITGAX; the disease is infection.
