  • Conclusions These comparative analyses illustrated the importance of antigen processing/presentation pathways mediated by both MHC class I and II in activating the immune system to initiate and maintain the immune-based response to anti-PD-1 therapy in metastatic melanoma patients. (bmj.com)
  • Entering unacceptable antigens for candidates increases the efficiency of organ allocation by screening off incompatible donors. (hrsa.gov)
  • Compact disc1 substances are a category of antigen-presenting substances distantly linked to main histocompatibility complicated (MHC)-encoded course I and course II substances. (eprf.ca)
  • The present study utilizes multiomics to examine the contribution of antigen presentation pathways in metastatic melanoma tumors either responsive or resistant to anti-PD-1 therapy. (bmj.com)
