Abstract
Using trypanosomes labeled with [75Se]-methionine experiments were conducted to investigate the respective roles of antibody, macrophage activation and complement in the removal of trypanosomes from the circulation of immune mice. Clearance in such animals was largely accomplished by antibody-mediated hepatic phagocytosis, which, at least in passively immunized animals, is dependent on opsonization involving C3 [complement component 3]. No evidence was found to suggest that intravascular lysis or activated macrophages are involved in immune clearance.
