Mechanisms of prostaglandin E2 (PGE2)-mediated immunosuppression in the tumor microenvironment (TME) have been previously reported. Here, the authors profile PGE2 functions in human cancer, suggesting that prostaglandin E2-mediated signaling impairs the activity of human CD8+ T cells and macrophages by altering bioenergetics and ribosome biogenesis.
