S1P-TREM2 axis protects immunosuppressive neutrophils from ferroptosis to promote tumour progression in hepatocellular carcinoma.
BACKGROUND Neutrophils are increasingly recognised as immunosuppressive drivers of hepatocellular carcinoma (HCC), yet their persistence in the oxidative, lipid-rich tumour microenvironment remains poorly understood. OBJECTIVE To elucidate the metabolic and molecular programmes that enable tumour-associated neutrophi...
