WebB-1 B cells develop from the fetal liver and disseminate into the periphery. They are principally found in the pleural and peritoneal cavities. Based on the surface expression of CD138, CD43, and CD5, two distinct subsets can be identified: B-1a and B-1b. B-1a B cells are the most abundant and express CD5, whereas B-1b B cells lack CD5 expression. WebRegulatory B cells. B cells have a positive role in priming adaptive CD4+ T cells, but not CD8+ T cells. The magnitude of CD4+ T-cell responses is reduced upon pathogen challenge in B-cell deficient or depleted mice. B cells are also able to dampen T-cell … Invariant natural killer T (iNKT) cells, also known as type I or classical NKT cells, are a distinct population of T cells that express an invariant aβ T-cell … T follicular helper cells (Tfh) are a specialized subset of CD4 + T cells that were first identified in the human tonsil.

To ask whether B1 cells could respond to CD40-mediated stimulation for proliferation and differentiation, and whether CD40-mediated signals are involved in the production of autoantibodies by B1 cells, we compared responses to our newly established agonistic …
