Tumor Cell-Derived CXCL2 Potentiates Neutrophil-Mediated Antitumor Immunity by Inhibiting Cholesterol Biosynthesis in Hepatocellular Carcinoma.

ABSTRACT: Hepatocellular carcinoma (HCC) is a major cause of cancer-related death worldwide. Despite the proven efficacy of immunotherapy against malignancies, a large proportion of patients with HCC fail to benefit from these efficacious agents because of their overwhelmingly immunosuppressive microenvironment. Therefore, there is an urgent need to identify key genes and develop effective strategies for reshaping the HCC microenvironment. Here, a significant downregulation of C-X-C motif chemokine ligand 2 (CXCL2) in HCC is identified due to gene copy number loss, which correlates with poor prognosis and suboptimal responsiveness to immunotherapy. Subsequently, it is found that CXCL2 can not only recruit neutrophils as expected, but also induce their polarization toward the antitumor type to curb H
