Studies on immune responses to larval cestodes in mice: a simple mechanism of non-specific immunosuppression in Mesocestoides corti-infected mice. 1977

G F Mitchell, and E Handman

After intraperitoneal (i.p.) injection of sheep erythrocytes (SRBC) or dinitrophenylated Ficoll (DNP-Ficoll), mice infected with the larval cestode, Mesocestoides corti, contain at least 20x fewer antibody-secreting cells (PFC) in their spleens (or spleens plus lymph nodes) than uninfected mice. By contrast, intravenous injection of antigen leads to normal PFC responses. Results of studies on the fate of labelled syngeneic erythrocytes and foreign proteins suggest that i.p. injected materials are retained in the inflamed peritoneal cavity. Sequestration of antigen, and its subsequent local destruction, presumably accounts for the markedly suppressed systemic immune responses induced by i.p. injected antigens in M. corti-infected mice.

UI	MeSH Term	Description	Entries
D006968	Hypersensitivity, Delayed	An increased reactivity to specific antigens mediated not by antibodies but by sensitized T CELLS.

D007165	Immunosuppression Therapy	Deliberate prevention or diminution of the host's immune response. It may be nonspecific as in the administration of immunosuppressive agents (drugs or radiation) or by lymphocyte depletion or may be specific as in desensitization or the simultaneous administration of antigen and immunosuppressive drugs.

D007275	Injections, Intravenous	Injections made into a vein for therapeutic or experimental purposes.	Intravenous Injections,Injection, Intravenous,Intravenous Injection
D007814	Larva	Wormlike or grublike stage, following the egg in the life cycle of insects, worms, and other metamorphosing animals.	Maggots,Tadpoles,Larvae,Maggot,Tadpole
D010537	Peritoneum	A membrane of squamous EPITHELIAL CELLS, the mesothelial cells, covered by apical MICROVILLI that allow rapid absorption of fluid and particles in the PERITONEAL CAVITY. The peritoneum is divided into parietal and visceral components. The parietal peritoneum covers the inside of the ABDOMINAL WALL. The visceral peritoneum covers the intraperitoneal organs. The double-layered peritoneum forms the MESENTERY that suspends these organs from the abdominal wall.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
