[IL-21 induces regulatory B cell differentiation and immunosuppressive effect through cognate interaction with T cells].
For a long time, it has been thinking that B cells regulate immune responses by producing antigen-specific antibodies. However, previous studies have revealed that specific B-cell subsets can also negatively regulate T-cell immune responses, and have been termed regulatory B cells. Recently, our study showed that mouse CD1d(hi)CD5(+) B cell subsets mainly produce IL-10. Therefore, we named thes...
متن کاملIL-2 and IL-21 confer opposing differentiation programs to CD8+ T cells for adoptive immunotherapy.
IL-2 and IL-21 are closely related cytokines that might have arisen by gene duplication. Both cytokines promote the function of effector CD8(+) T cells, but their distinct effects on antigen-driven differentiation of naive CD8(+) T cells into effector CD8(+) T cells are not clearly understood. We found that antigen-induced expression of Eomesodermin (Eomes) and maturation of naive CD8(+) T cell...
متن کاملIL-21 Regulates the Differentiation of a Human γδ T Cell Subset Equipped with B Cell Helper Activity
Vγ9Vδ2 T lymphocytes recognize nonpeptidic antigens without presentation by MHC molecules and display pleiotropic features. Here we report that coculture of Vγ9Vδ2 cells with phosphoantigen and IL-21 leads to selective expression of the transcription repressor Bcl-6 and polarization toward a lymphocyte subset displaying features of follicular B-helper T (T(FH)) cells. T(FH)-like Vγ9Vδ2 cells ha...
متن کاملTGF-β Enhanced IL-21-Induced Differentiation of Human IL-21-Producing CD4+ T Cells via Smad3
IL-21 has pleiotropic effects on innate and adaptive immune response, and plays an important role in the development of autoimmune disease and antitumor activity. It has been reported that IL-21 is produced by CD4(+) T cells and NKT cells. However, the differentiation of IL-21-producing CD4(+) T cells in humans remains largely unclear. In the present study, we showed that cytokines of IL-1β, IL...
متن کاملIL-21 and T follicular helper cells.
Upon encounter with antigen, CD4(+) T cells differentiate into effector T(h) subsets with distinctive functions that are related to their unique cytokine profiles and anatomical locations. One of the most important T(h) functions is to provide signals to developing B cells that induce specific and appropriate antibody responses. The major CD4(+) T cell subset that helps B cells is the T follicu...
