Cancer stem cells contribute to cancer evasion and relapse by suppressing the immune response. Here, the authors identify sterol O-acyltransferase 1 (SOAT1) as a cancer stem cell immune checkpoint and propose that SOAT1 inhibition results in oxysterol-mediated reprogramming of intratumoral regulatory T cells via a trans-cellular 20SOHC-GPR132, ultimately enhancing anti-tumor immunity in various preclinical mouse models.
