Targeted depletion of an MDSC subset unmasks pancreatic ductal adenocarcinoma to adaptive immunity

Abstract

Neoplastic ductal cells of the pancreas induce distinct myeloid cell subsets that promote tumour cell survival and accumulation. Targeted depletion of a single myeloid subset, the Gr-MDSC, can unmask an endogenous T cell response, disclosing an unexpected latent immunity and invoking targeting of Gr-MDSC as a potential strategy to exploit for treating this highly lethal disease.
