Anti- antibodies attach to mouse cancer cell lines but not normal mouse lymphocytes.

Summary of "Anti- antibodies attach to mouse cancer cell lines but not normal mouse lymphocytes."

is prevalent intracellular parasite and a cause of worldwide infection in the human population. An inhibitory effect of this parasite on cancer growth has been demonstrated in cell culture and animal models. To determine whether the anticancer activities of are associated with host immune response, in the current study the reactivity of anti- antiserum with the surface of cancer cell lines was investigated. Anti- antibodies were raised in rabbit and the reaction of this antiserum in comparison with other anti-parasite antisera (anti-, anti-hydatid cyst fluid, anti-protoscolices antigens) with mouse melanoma or breast cancer cells lines was investigated using flow cytometry. Anti- antiserum reacted markedly with the surface of mouse melanoma and breast cancer cells, and less so with the normal mouse spleen lymphocytes. Meanwhile, the other anti-parasite antisera did not react strongly with the surface of cancer cells compared with normal mouse spleen lymphocytes. In summary, it has been demonstrated herein that anti- antiserum may selectively react with the surface of mouse cancer cells but not with normal mouse spleen lymphocytes. Therefore, further study on anti- antibodies may be useful for directing the application of selective drug delivery in cancer treatment.

Medical and Biotech [MESH] Definitions

Cell lines whose original growing procedure consisted being transferred (T) every 3 days and plated at 300,000 cells per plate (J Cell Biol 17:299-313, 1963). Lines have been developed using several different strains of mice. Tissues are usually fibroblasts derived from mouse embryos but other types and sources have been developed as well. The 3T3 lines are valuable in vitro host systems for oncogenic virus transformation studies, since 3T3 cells possess a high sensitivity to CONTACT INHIBITION.

Anti-CD3 monoclonal antibody that exerts immunosuppressive effects by inducing peripheral T-cell depletion and modulation of the T-cell receptor complex (CD3/Ti). This biochemically purified IMMUNOGLOBULIN G is obtained through the fusion of mouse myeloma cells to lymphocytes from immunized animals to produce hybridomas that secrete specific antibodies to the T3 (CD3) antigens of human T-lymphocytes. It is often used as an IMMUNOSUPPRESSIVE AGENTS in TRANSPLANTATION.

The phosphoprotein encoded by the BRCA1 gene (GENE, BRCA1). In normal cells the BRCA1 protein is localized in the nucleus, whereas in the majority of breast cancer cell lines and in malignant pleural effusions from breast cancer patients, it is localized mainly in the cytoplasm. (Science 1995;270(5237):713,789-91)

Antibodies which react with the individual structural determinants (idiotopes) on the variable region of other antibodies.

Antibodies elicited in a different species from which the antigen originated. These antibodies are directed against a wide variety of interspecies-specific antigens, the best known of which are Forssman, Hanganutziu-Deicher (H-D), and Paul-Bunnell (P-B). Incidence of antibodies to these antigens--i.e., the phenomenon of heterophile antibody response--is useful in the serodiagnosis, pathogenesis, and prognosis of infection and latent infectious states as well as in cancer classification.
