STING1 and pancreatic neoplasm: To rigorously establish a role for STING agonist in T cell accumulation and activation within the previously suppressed pancreatic tumors, a 31-plex bead-based assay was performed to quantify levels of inflammatory mediators within the pancreatic tumor microenvironment on day 19, 3 days after a second DMXAA injection (Fig. 4a).
