    Lipid-associated macrophages (LAMs) are a distinct subpopulation of tumor-associated macrophages in pancreatic ductal adenocarcinoma (PDAC).

  • 2

    LAMs are characterized by co-expression of TREM2, APOE, CD9, and lipid-handling genes, correlating with poor prognosis in PDAC patients.

  • 3

    Metabolic rewiring in LAMs involves CD36-mediated lipid uptake and dysregulated cholesterol efflux, contributing to their immunosuppressive phenotype.

  • 4

    LAMs directly suppress CD8+ T cells and NK cells, interacting bidirectionally with cancer-associated fibroblasts in the PDAC microenvironment.

  • 5

    Preclinical targeting of LAMs shows promise, but challenges remain regarding toxicity and delivery of therapeutic strategies.
