An MD Anderson AI model reads where T cells gather in tumor tissue, and points at mucin as a wall that may keep them out
Researchers at the University of Texas MD Anderson Cancer Center and collaborating Texas institutions published an AI model called SPACER in Nature Biomedical Engineering. It reads spatial maps of gene activity in intact tissue and looks at groups of neighboring cells to infer why immune cells gather in some regions and avoid others. The team ran it on 37 datasets and reports it was four to 21 times more effective than existing approaches on its benchmark tasks. Its leading finding is that mucins, sugar coated proteins many cancers overproduce, may form a physical barrier that keeps T cells away from tumors. In melanoma and gastric cancer datasets, tumors with more mucin went with poorer response to checkpoint drugs. The finding is an association in existing data. The researchers describe it as an idea to test in the lab, and the release reports no use of the tool in patient care.

SPACER revealed that tumors expressing genes involved in antigen presentation, the process by which cells display protein fragments for immune cells to inspect, were more likely to attract T cells.UT MD Anderson Cancer Center, Research News, AI tool reveals what attracts immune cells to tumors and what keeps them away, October 13th, 2026 Primary source, official · mdanderson.org
Additionally, the researchers uncovered evidence that mucins, a family of large, sugar-coated proteins produced by many cancers, may help create physical barriers that keep T cells away from tumors.UT MD Anderson Cancer Center, Research News, AI tool reveals what attracts immune cells to tumors and what keeps them away, October 13th, 2026 Primary source, official · mdanderson.org
