In this issue of Immunity, Hu et al. report that in the tumor microenvironment, eATP signals through the receptor P2RY2 on cancer cells, triggering the COX-PGE2 pathway and thereby immune suppression and immunotherapy resistance. These findings identify eATP as the upstream signal driving PGE2 expression, with therapeutic implications.dlvr.it
