CD4 T cell help for B cells is critical for effective antibody responses. While many of the molecules involved in helper functions of naïve CD4 T cells have been characterized, much less is known about the helper capabilities of memory CD4 T cells, an important consideration for the design of vaccines that aim to prime protective memory CD4 T cells. Here we demonstrate that mouse memory CD4 T cells enable B cells to expand more rapidly and class switch earlier than primary responding CD4 T cells. This accelerated response does not require large numbers of memory cells and similar numbers of primary responding cells provide less effective help than memory cells. However, only memory CD4 T cells that express the B cell follicle homing molecule, CXCR5, are able to accelerate the response. Therefore, the rapidity of the antibody response depends on the ability of CD4 memory T cells to migrate quickly towards B cells.
