Abstract B083: Mutant KRAS cooperates with the hypoxic tumor microenvironment to drive immunosuppressive macrophages via a paracrine PGE2/GM-CSF axis
Hypoxia is known to drive an immunosuppressive microenvironment in pancreatic ductal adenocarcinoma (PDAC). However, the underlying immunosuppressive mechanisms remain unclear. Here, we hypothesized that hypoxia-induced factors secreted from tumor cells promoted immunosuppressive macrophages in PDAC. We tr...
