Very recent works have demonstrated that neutrophil-released neutrophil elastase (ELANE) or its homolog (porcine pancreatic elastase (PPE)) can kill many kinds of cancer cell types (35 different cancer cell lines) while preserving non-cancer cells and trigger an abscopal effect mediated by cytotoxic T lymphocytes to attenuate primary and distal tumor growth26,27. This evidence concerns the gene ELANE and cancer.
