Alternative definition : KEGG: The intestine is the largest lymphoid tissue in the body. One striking feature
of intestinal immunity is its ability to generate great amounts of noninflammatory
immunoglobulin A (IgA) antibodies that serve as the first line of defense against
microorganisms. The basic map of IgA production includes induction of mucosal B cells
in the Peyer's patches, circulation through the bloodstream and homing to intestinal
mucosa of IgA-committed plasma cells, and local antibody production for export across
the intestinal membranes. Multiple cytokines, including TGF-beta, IL-10, IL-4, IL-5,
and IL-6, are required to promote IgA class switching and terminal differentiation
process of the B cells. Secreted IgA promotes immune exclusion by entrapping dietary
antigens and microorganisms in the mucus and functions for neutralization of toxins
and pathogenic microbes.;
