CD4-independent T cells impair TCR triggering of CD4-dependent T cells: a putative mechanism for T cell affinity maturation.

abstract：:In humans and mice, mucosal immune responses are dominated by IgA antibodies and the cytokine TGF-β, suppressing unwanted immune reactions but also targeting Ig class switching to IgA. It had been suggested that eosinophils promote the generation and maintenance of mucosal IgA-expressing plasma cells. Here, we demonst...
