Scientists Made Cancer Cells Look Like Bacteria So Immune Cells Would Eat Them

Researchers coated cancer cells with molecules found on bacteria, tricking macrophages, immune cells that normally hunt germs, into attacking and engulfing them instead of leaving them alone. The coating raised engulfment from about 20% to 70% in lab tests and slowed tumor growth in mice, but the approach remains preclinical and untested for human safety.
