Lymphoid cell responses in parasitic helminth infections.
The cellular responses during experimental ascariasis provide a mechanism whereby effector systems are mobilized rapidly and locally, resulting in the prompt response which is evident on reinfection. It is proposed that the products of activated "T" lymphocytes facilitate local accumulation of lymphoid cells which, later, as specific antibody-producing cells provide the mediators (e.g. opsonizing antibody) responsible for mechanisms which destroy the parasite. While the mechanisms causing death of the parasite are still unknown, our present studies will provide an explanation of events that prepare for this event.
