title: A receptor for IgA on human T lymphocytes.
abstract: Receptors for IgA antibody-antigen complexes were demonstrated on 2 to 18% (mean 6.7%) of human peripheral blood T cells. The proportion of cells bearing detectable IgA receptors was low in freshly prepared T cells and increased in number after 18 to 24 hr of culture similar to the time course of appearance of the Tmu receptor. These T receptors were shown to be distinctly different from Fc-IgM and Fc-IgG receptors on T cells by blocking studies with purified IgA, IgG, and IgM.
