The target cell antigen(s) on tumor cells and on protozoan parasites recognized by NK and nonspecific cytotoxic cells (NCC) has not yet been specifically identified. NCC may be the teleost equivalent of NK cells and IL-2-activated NK cells. A ligand recognized by NCC has been identified.

Expression of protozoan antigens by hybrids between Leishmania mexicana and myeloma SP2/0
Journal of Immunological Methods, 1984Hybrid cells were obtained between Leishmania mexicana promastigotes and mouse myeloma SP2/0 cells, and examined for expression of leishmanial antigens. A ratio of 1:10 of myeloma to T. cruzi cells was unsuccessful because of outgrowth of non-fused cells.

A sensitive immunoassay for detecting antibodies to the protozoan parasite of poultry Eimeria tenella, has been developed. Microspheres coated with parasite antigen are reacted with antibody-containing chicken serum followed by a fluorescent labeled second antibody and analyzed by flow cytometry.

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 ...

Abstract A novel approach for the iterative synthesis of the antigenic branched phosphoglycan of the protozoan parasite Leishmania major is presented that exploits remarkable dual selectivity in the functionalization of d -lactal, providing flexibility to extend the PG chain either towards the reducing or nonreducing end.

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.).

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 ...

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.

Veterinary Immunology and Immunopathology, 1996
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 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 ...
