WebNov 11, 2013 · Investigations utilizing mutant and knock-out mice suggest that MHC class II restricted cytolysis by murine CD4+T cells is predominantly mediated by the death receptor system (17, 18) which is in contrast to MHC class I restricted cytolysis by CD8+CTLs relying mainly on perforin and granzymes. WebSep 22, 2024 · CD8 and CD4 T cell activation are both required for a strong and long-lasting T cell immune response. Endogenously expressed proteins are readily processed by the MHC class I antigen presentation pathway, enabling activation of CD8+ T cells.
