    MHC class I downregulation is a general mechanism by which tumor cells can escape from T-cell-mediated immunity. Therefore, successful imunotherapeutic and vaccination protocols should be optimized against tumors with distinct cell surface expression of the MHC class I molecules. Mechanisms leading to protective immunity may vary in different models with respect to the particular tumors, e.g. to their levels of residual expression of the MHC class I molecules on tumor cells or inducibility of MHC class I expression. Notably, both CD8+ cell-mediated immunity and MHC class I-unrestricted mechanisms can take place against MHC class I-deficient tumors. Since MHC class I downregulation is frequently reversible by cytokines and also by activation of epigenetically silenced genes, an attractive strategy is to elicit specific cell-mediated immunity combined with restoration of MHC class I expression on tumor cells.
