Autoantibody Production in Rabbits VI. THE PRODUCTION OF AUTOANTIBODIES AGAINST RABBIT GASTRIC, ILEAL AND COLONIC MUCOSA.

Rabbits injected with a homogenate of rat gut mucosa produce auto-antibodies reacting with their own gut mucosa. Different organ-specific antigens present in the stomach mucosa and colonic and ileal mucosae can be demonstrated in this way. The antigens concerned are in the mucous secretions as well as in certain epithelial cells and may be mucopolysaccharides. [ABSTRACT FROM AUTHOR]
