Secretory IgA produced in the epithelium of mucosal surfaces has several functions in protective immunity. Am pathogens or toxins in the gastrointestinal tract lumen or in epithelial ce!l endosomes, neutralization of pathoge epithelial barrier, and transport of pathogens or toxins across M cells for delivery to lamina propria dendritic cel the common feature that they: Are efficient at inducing opsonization of pathogens for uptake by phagocytes O Are efficient at inducing complement activation O Fail to completely protect the epithelium from cytotoxic effects of pathogens O Fail to induce lotal inflammation in the gastrointestinal epithelium Mice lacking the poly Ig receptor (plgR) have an immunodeficiency disease characterized by increased suscept and an increase in the penetration of commensal microbes into the body's tissues. Yet, a genetic deficlency in the antibodies is the most common form of human immunodeficiency, and is generally a mild disease and often ever
