title: The influence of oral immunization on local and systemic immune responses to heterologous antigens.
abstract: Oral immunization with 25 mg/day of ovalbumin resulted in a number of changes in non-specific immune responsiveness, including increases in antibody produced to T-dependent but not T-independent antigens and the abrogation of tolerance induced by both oral and intravenous routes. The effect was transient, sex- and strain-dependent. Evidence suggests that it is a consequence of cell-mediated immunity to the oral immunogen.
