What is it about?
The immune system protects from cancer, including bladder cancer (BLCA). Major histocompatibility complex (MHC) class I molecules show bladder tumor antigens to cytotoxic T cells that start killing tumor cells. Defects in this process may result in tumor ocurrence, recurrence and progression. This review presents defects in the MHC class I pathway in BLCA and discusses how to limit or counteract these defects in BLCA immunotherapy.

Why is it important?
The occurrence and recurrence of BLCA depend on MHC class I expression. BLCA tumors positive for MHC class I may be eliminated after surgical removal due to efficient immune response, while BLCA tumors heterogenous and negative for MHC class I recur and progress. If the changes are not genetic, MHC class I levels can be recovered by various immunomodulatory agents.
