The Role Of Secretory Antibodies In Mucosal Homeostasis

Grant number: 400011


This proposal will address the role of the antibodies that are present in all secretions from the gut, the lungs, the eye and mouth in maintaining the health of the mucosal (ie mucous covered) tissues from which they originate. It has long been presumed that these antibodies stop bacteria and other pathogens adhering to the surface of mucosal tissues. Our preliminary findings suggest that they have another very important role in removing excess inflammatory material from beneath the lining of the mucosal tissues, to prevent recognition of this material by the immune system. Such recognition could result in serious consequences both locally (ie. in the gut) and more distally eg. in the pnacre..
