📝 英文原版摘要

Proceedings of the National Academy of Sciences, Volume 123, Issue 11, March 2026. <br />SignificanceImmune checkpoint inhibitors (ICIs) have transformed cancer therapy, yet many human papillomavirus (HPV)-positive head and neck cancers remain resistant due to the downregulation of antigen presentation mechanisms. We identify the ubiquitin ...
