FCRL5 and influenza: In a non-peer-reviewed manuscript posted to BioRxiv, Nellore et al. [38] showed that FcRL5+CD11c+T-bet+ activated MBCs present shortly after primary influenza immunization give rise to plasmablasts upon secondary immunization a year later, providing further support for a role of FcRL5 and CD11c as markers of long-lived B cell memory.
