Multimodal mapping of the tumor and peripheral blood immune landscape in human pancreatic cancer

NG Steele, ES Carpenter, SB Kemp, VR Sirihorachai… - Nature Cancer, 2020 - nature.com
Pancreatic ductal adenocarcinoma (PDA) is characterized by an immune-suppressive tumor
microenvironment that renders it largely refractory to immunotherapy. We implemented a …

Regulatory T-cell depletion alters the tumor microenvironment and accelerates pancreatic carcinogenesis

…, CJ Halbrook, RE Menjivar, SB Kemp, VR Sirihorachai… - Cancer discovery, 2020 - AACR
Here, we describe an unexpected cross-talk between Tregs and fibroblasts in pancreatic
cancer. Treg depletion resulted in differentiation of inflammatory fibroblast subsets, in turn …
