Common Antigenic Determinants between Acetylcholine Receptor and Protozoan Membranes
1986It has been reported that sera from humans infected with the protozoan Leishmania donovani contain antibodies to skeletal muscle constituents. In an attempt to find antigenic similarities between specific muscle antigens and Leishmania membrane antigens which could explain the crossreactivity observed we used a library of well characterized monoclonal ...

The antigen on the protozoan parasite Tetrahymena pyriformis recognized by catfish nonspecific cytotoxic cells (NCC) is a 46- to 48-kDa protein referred to as NKTag. The complete cDNA-derived amino acid sequence of NKTag has been obtained. The antigenic determinant of NKTag corresponding to the NCC binding site has been determined with synthetic ...

Theileria annulata infection is controlled by MHC class I restricted cytotoxic T cell killing of infected cells. The long term persistence of parasite suggests that it employs a mechanism to avoid immune surveillance. In this paper we describe the modification of BoLA class I antigens on the surface of Theileria annulata transformed lymphoblastoid ...

Abstract Subcellular fractions of Leishmania enriettii promastigotes were prepared by differential centrifugation of parasite homogenates. Antigenic activities of these fractions were determined by microcomplement fixation and indirect radioimmunoassay methods using L. enriettii immune guinea-pig serum.

Monoclonal antibody (MoAb) 18C2, prepared against a human EBV transformed lymphoblastic cell line (NC‐37) is specific for a target cell ligand recognized by fish NCC and by mammalian NK cells. MoAb 18C2 inhibits the lysis of a variety of transformed murine and human cells (e. g. NC‐37, YAC‐1, K562, etc.).

Abstract Experiments were conducted to measure the agglutinating antibody response of channel catfish to a particulate and a soluble antigen administered simultaneously by one of three routes. Specific antibody production in response to administration of particulate brucella tube-test antigen via intramuscular injection, oral drench, and topical ...

SummaryIn this methodological paper an immunoprecipitation technique has been optimised for the identification of antigens of Plasmodium berghei‐infected blood which react with antibody specificities in a host‐protective antiserum. Extracted 3H‐leucine biosynthetically‐labelled products of infected blood were sequentially reacted and precipitated with ...

The precise molecular mechanisms underlying the switch between the two developmental stages of Toxoplasma gondii, and the metabolic adaptations occurring during this stage conversion are poorly understood. Because inhibitors of mitochondrial respiration are known to trigger differentiation from tachyzoite into bradyzoite stages, we believe that some of

Thymus Dependency and Chronic Antigenic Stimulation: Immunity to Parasitic Protozoans and Helminths
1973Knowledge of the immunology of protozoal and helminthic infections has lagged behind developments in the field of immunology as a whole; some significant advances have been made in recent years, but the mechanisms which determine the protective immune responses to these parasites are still obscure.
