Abstract 4074: Heat shock protein 90 inhibitors alter pancreatic stellate cell cytokine production and enhances the efficacy of immune checkpoint blockade in pancreatic cancer

Pancreatic ductal adenocarcinoma (PDAC) has a prominent fibrotic stroma, which is a result of interactions between tumor, immune and pancreatic stellate cells (PSC). Prior work from our laboratory has defined a role for stroma-derived cytokines such as IL-6 as a significant barrier restraining immunity against PDAC. Our group is pursuing novel approaches to target pathways in the tumor microenvironment (TME), in an effort to improve access of...
