Observational study investigates intrapancreatic adipocytes' impact on tumor immunity in pancreatic cancer, suggesting new treatment targets.

This research aims to understand how intrapancreatic adipocytes contribute to pancreatic cancer progression and their impact on tumor immunity.
MRI imaging analysis on pancreatic cancer patients
H&E staining of histological sections
Adipoq-Cre lineage tracing mouse model
Single-cell nuclear transcriptome sequencing of adipocytes
Experimental validation of IGFBP2 role in adipocyte browning
Intra-pancreatic fat fraction significantly increased in pancreatic cancer patients compared to controls.
Adipocytes in pancreatic cancer originate from neogenesis and trans-differentiation rather than proliferation.
Browning of infiltrating adipocytes created an immunosuppressive environment that promotes tumor progression.
IGFBP2 was found to be crucial for inducing adipocyte browning.
Combination of IGFBP2 targeting and anti-PD1 therapy effectively reduced cancer progression.

Wang et al. (2026) studied this question.
