Memory CD4 T cells that express CXCR5 provide accelerated help to B cells.
CD4 T cell help for B cells is critical for effective Ab responses. Although many of the molecules involved in helper functions of naive 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. In this study, we demonstrate that memory CD4 T ...

متن کاملCD4+ T cells from MHC II-dependent thymocyte–thymocyte interaction provide efficient help for B cells
Recently, a novel CD4(+) T-cell developmental pathway was reported that generates thymocyte-thymocyte (T-T) CD4(+) T cells. We established a mouse system (CIITA(tg)CIITApIV(-/-)) where thymic positive selection occurred only by major histocompatibility complex (MHC) class II(+) thymocytes. T-T CD4(+) T cells selected via MHC class II-dependent T-T interaction are comprised of PLZF-negative and ...
متن کاملRequirement of B cells for generating CD4+ T cell memory.
B cells can influence T cell responses by directly presenting Ag or by secreting Ab that binds to Ag to form immunogenic complexes. Conflicting evidence suggests that persisting Ag-Ab complexes propagate long-term T cell memory; yet, other data indicate that memory cells can survive without specific Ag or MHC. In this study, the roles of B cells and Ag-Ab complexes in T cell responses to lympho...
متن کاملCD27 instructs CD4+ T cells to provide help for the memory CD8+ T cell response after protein immunization.
For optimal quality, memory CD8(+) T cells require CD4(+) T cell help. We have examined whether CD4(+) T cells require CD27 to deliver this help, in a model of intranasal OVA protein immunization. CD27 deficiency reduced the capacity of CD4(+) T cells to support Ag-specific CD8(+) T cell accumulation at the tissue site after primary and secondary immunization. CD27-dependent CD4(+) T cell help ...
