Functions of tonsils in the mucosal immune system of the upper respiratory tract using a novel animal model, Suncus murinus

Abstract

The FITC-labeled S. aureus particles were detected in tubal tonsils and also in cervical lymph nodes. Total IgA-producing cells and OVA-specific antibody-producing cells were identified in the immunized tubal tonsils. Trans-external ear meatus immunization of tubal tonsils also evoked systemic antibody responses.
