Abstract

Patients with pancreatic ductal adenocarcinoma do not benefit from checkpoint blockade. However, human tumors harbor evidence of adaptive immunity in clonally expanded T-cell populations. Immune intact modeling of human tumors identifies stromal sequestration as a mechanism of immune escape. Targeting the stroma combined with checkpoint blockade unleashes antitumor immunity.<i>See related article by Seo et al., p. 3934</i>.
