DescriptionB16-OVA MO4 Mouse Melanoma Cell Line
OverviewThe immune system can recognize and destroy tumors. Cytotoxic T lymphocytes (CTLs) kill neoplastic (or virally infected) cells after recognizing antigenic peptides bound to major histocompatibility complex (MHC) class I molecules on their surface. These peptides are derived from antigens that are degraded in the cytosol of the affected cell. Immunizations with killed pathogens or their proteins do not generally elicit CTLs, because exogenous proteins cannot enter the cytosol (to be presented). However, antigens that are internalized into phagocytic cells can enter the cytosol and be processed for class I presentation. Immunization with a purified antigen attached to an avidly phagocytized particle primes CTLs, which in turn
protect animals from subsequent challenge with tumors transfected with the antigen gene.

Source
Tumor rejection antigens – TRAs – differ from any other protein synthesized by the cell in that the host is intolerant to them. Thus virtually any foreign protein synthesized by a tumor, including those expressed from foreign antigen genes transfected into tumor cells, should function and behave like TRAs. This hypothesis was tested in a murine tumor model developed by transfecting the chicken ovalbumin gene into the C57BL/6 (H-2b haplotype)-derived murine melanoma cell line B16, followed by selection and isolation of the ovalbumin (OVA)-transfected B16 clone B16-OVA MO4.1
In in vitro challenge, B16-OVA MO4 cells stimulated the OVA+ Kb-specific T-cell hybridoma RF33.70 to produce interleukin-2 whereas untransfected B16 cells did not. Injected intradermally into syngeneic C57Bl/6 mice, both B16 and B16-OVA MO4 grew progressively, metastasized, and killed the animals showing that expression of the ovalbumin antigen alone does not render this tumor sufficiently immunogenic to be rejected. Subcutaneous immunization of C57Bl/6 mice with ovalbumin conjugated to iron beads (OVA-Fe), however, protected B16-OVA MO4 (but not B16) challenged animals both from local tumor growth and death. This approach could be exploited to develop tumor and viral vaccines.1
