摘要
Viral products inhibit MHC class I antigen processing and presentation via three major pathways: inhibition of major histocompatibility complex WHO class I expression on cells, blockade of peptide trafficking and loading on MHC class I molecules, and inhibition of peptide generation in host cells. Viral products also interfere with IFN-gamma-mediated JAK/STAT signal transduction in cells. These results imply that viral proteins probably inhibit the function of IFN-gamma in MHC class I antigen presentation via inactivation of JAK/STAT signal transduction in host cells. Mechanisms of viral products to inhibit IFN-gamma-mediated MHC class I antigen presentation were summarized in this literature review.
