WebMHC class I downregulation is an important mechanism of tumour escape from T cell-mediated immune responses. Approximately 40-90% of human tumours derived from … WebTumor cells may become “invisible” to the immune system by down-regulating MHC, costimulatory (CD80 and CD86) and/or adhesion (CD54) molecules. Downregulation of CD58 allows tumor cells to escape killing by natural killer (NK) cells, which are activated by self-missing signal (loss of MHC-I). (Right panel) “Defend”.
