WebCD8+ T-cells are a critical component of the cellular immune response and they play an important role in the control of viral infection. During HIV infection, CD8+ T-cells are able to recognize infected cells through an MHC-I dependent process and are able to lyse cells harboring viral infection by the secretion of perforin and granzymes. WebThe CD3 + T-cell co-receptor and CD4 + T-cells are of pivotal importance in activating both the cytotoxic T-cell (CD8 + naive T-cells). In order to assess the lineage differentiation of T-cells in mediating anti-tumor immune responses, CD3, CD4, and CD8 were quantified in extracted cells of splenocytes and tumors of treated mice.
