Association of Neuroblastoma (NB) SH-SY5Y Cells with Antibodies of Parasitic Origin (Anti- and Anti-).

It is little known that trophozoites and eggs can reduce tumors in vitro and animal models. Although this has been known for many years, the mechanism that induces the antitumor effect in these parasites is still not known. We employed Western blot (WB) and immunofluorescence (IFC) by confocal microscopy to explore the potential protein binding between neuroblastoma (NB) SH-SY5Y cells and anti- and anti- antibodies.

Tumor-Suppressive Cross-Linking of Anti- Antibodies in Acute Lymphoblastic Leukemia.

Parasites have been associated with possible anticancer activity, including , which has been linked to inhibiting the growth of solid tumors. To better understand this antitumor effect, we investigated the association of anti- antibodies with B cells of the acute lymphoblastic leukemia (ALL) SUPB15 cell line. The antibodies were generated in rabbits.

Antigenic Proteins Shared with Acute Lymphoblastic Leukemia and Neuroblastoma.

Research studies indicate that immunization with protein extracts of , the protozoan parasite that causes Chagas disease, prevents the appearance of tumors in 60% of mice injected with the murine lung carcinoma tumor line. The molecular basis of this process is unknown, although the presence of specific antigens in tumor cells and on the surface of suggests an antiparasitic immune response, with an effective cross-reaction against cancer cells, hence the importance to identify the antigens involved and determine their potential as target cells in anticancer therapy. This study aimed to determine the presence of antigenic proteins of shared with acute lymphoblastic leukemia and neuroblastoma cells.
