Neutrophil extracellular traps induced by tumour-derived NGAL reprogram CAF subtypes via ITGA5 to promote tumour progression in pancreatic cancer
Background Pancreatic ductal adenocarcinoma (PDAC) is largely refractory to immune checkpoint blockade, owing to its immunosuppressive tumour microenvironment. Neutrophil extracellular traps (NETs) accumulate in PDAC and correlate with disease progression, yet whether NETs reprogram cancer-associated fibroblast (CAF) h...
