Secretory IgA: Designed for Anti-Microbial Defense
Prevention of infections by vaccination remains a compelling goal to improve public health. Mucosal vaccines would make immunization procedures easier, be better suited for mass administration, and most efficiently induce immune exclusion - a term coined for non-inflammatory antibody shielding of internal body surfaces, mediated principally by secretory immunoglobulin A (SIgA). The exported ant...
متن کاملRecombinant secretory IgA for immune intervention against mucosal pathogens.
Mucosal epithelia of the human body, including the lining of the digestive, respiratory and urogenital tracts, comprises a vast surface permanently exposed to attack by exogenous pathogens. Protection of mucosal surfaces against colonization and possible invasion by pathogenic microorganisms is provided by a combination of constitutive non-specific substances such as mucus, lysozyme, lactoferri...
متن کاملMulti-Faceted Functions of Secretory IgA at Mucosal Surfaces
Secretory IgA (SIgA) plays an important role in the protection and homeostatic regulation of intestinal, respiratory, and urogenital mucosal epithelia separating the outside environment from the inside of the body. This primary function of SIgA is referred to as immune exclusion, a process that limits the access of numerous microorganisms and mucosal antigens to these thin and vulnerable mucosa...
متن کاملTLR-Dependent Human Mucosal Epithelial Cell Responses to Microbial Pathogens
Toll-like receptor (TLR) signaling represents one of the best studied pathways to implement defense mechanisms against invading microbes in human being as well as in animals. TLRs respond to specific microbial ligands and to danger signals produced by the host during infection, and initiate downstream cascades that activate both innate and adaptive immunity. TLRs are expressed by professional i...
متن کاملMucosal secretory IgA and secretory piece in adult coeliac disease.
Immunofluorescence studies with specific antisera to secretory IgA (11S IgA) and secretory piece were carried out on the jejunal mucosa of nine patients with adult coeliac disease (treated and untreated). The results were compared with those obtained in four normal patients and in four patients with local and systemic IgA (7S) deficiency. 11S IgA and secretory piece were localized to the upper ...
