Deskripsi
Cancer cells downregulate surface expression of major histocompatibility complex I (MHC-I) for immune evasion. Here, the authors show that rapid mitochondrial fission activates the ER-stress response leading to reduced MHC-I complex formation and cell surface expression in solid cancer cells; moreover inhibition of mitochondrial fission increases the immune-mediated anticancer response in murine models.
