Passage of Dietary Antigens in Man: Kinetics of Appearance in Serum and Characterization of Free and Antibody-Bound Antigen
The passage of dietary antigens from the human gastrointestinal tract to the blood was indicated already in the 1920’s, by experiments with passive cutaneous anaphylaxis (1). Quantitation of absorbed dietary antigens in healthy adults was later accomplished by the use of radioimmunological techniques (2). Further, dietary antigens have been reported in circulating immune complexes in atopic patients and in normals (3,4) and in patients with IgA-deficiency (5).
