WebFor successful immunotherapy for cancer, it is important to understand the immunological status of tumor antigen-specific CD8 + T cells in the tumor microenvironment during tumor progression. In this study, we monitored the behavior of B16OVA-Luc cells in mice immunized with a model tumor antigen ovalbumin (OVA). WebCD8 + T cells are recognized as T C cells once they become activated and are generally classified as having a pre-defined cytotoxic role within the immune system. However, CD8 + T cells also have the ability to make some cytokines, such as TNF-α and IFN-γ, with antitumour and antimicrobial effects. Development [ edit]
