Regulation of IgA secretion by T cell clones derived from the human gastrointestinal tract

, : Regulation of IgA secretion by T cell clones derived from the human gastrointestinal tract. Journal of Immunology 140(6): 1874-1882

The role of T cells in Ig isotype regulation is still unclear. To address this question, we generated mitogen-stimulated T cell clones from normal human lymphoid follicles of the gut-associated lymphoid tissue (appendix). Both the T cell clones and clonal supernatants provided preferential help for IgA secretion by PWM-stimulated B cells. Many of these CD3+, CD4+, 4B4+, DR+ helper clones co-expressed Fc-.gamma. and Fc-.alpha.

PON1 and PON3 are circulating in serum attached to high-density lipoprotein fraction (HDL), whereas PON2 is...
