发现棕榈酸通过ZDHHC24介导的B7H3棕榈酰化机制,调控CD8⁺ T细胞抗肿瘤活性,揭示了代谢产物参与肿瘤免疫逃逸的新途径

📝 英文原版摘要

<p>Nature Communications, Published online: 19 January 2026; <a href="https://www.nature.com/articles/s41467-026-68525-x">doi:10.1038/s41467-026-68525-x</a></p>B7H3 is an immune checkpoint overexpressed in many cancers and associated with tumor immune evasion. Here, the authors discover that in colorectal cancer, particularly microsatellite-stable tumors, palmitic acid promotes ZDHHC24- mediated B7H3 palmitoylation, regulating CD8⁺ T cell antitumor activity.
