Firing up neutrophil anti-tumor immunity with cocktails

Neutrophils constitute a considerable proportion of all leukocytes found in tumors and are essential for promoting tumor growth. In this issue, Linde et al. demonstrate that an antibody cocktail therapy consisting of tumor necrosis factor (TNF), anti-CD40 monoclonal antibody, and tumor-binding antibody can boost the anti-tumor activity of neutrophils.

Neutrophil-activating therapy for the treatment of cancerLinde et al.Cancer CellJanuary 26, 2023In BriefLinde et al. describe a cancer therapy that activates neutrophils to infiltrate and eradicate tumors and reduce metastatic seeding. The authors elucidate the responsible mechanism, which involves complement component C5a, leukotriene B4, and reactive oxygen species, and demonstrate the potential of harnessing neutrophils through inflammatory activation to drive tumor clearance.
