Neutrophils are essential defenders during inflammation and modulators of key cancer-associated activities with pro- or antitumor functions. describe a cancer therapy that activates neutrophils to infiltrate and eradicate tumors and reduce metastatic seeding. To adapt to and optimally respond to environmental changes in a timely manner, most organisms have developed an internal timekeeping system that allows self-sustained, oscillating physiological processes that cycle with a ~24 h period – the circadian rhythm. Finally, we wanted to determine the relevance of a therapy-elicited neutrophil response in human disease. Neutrophils escort circulating tumour cells to enable cell cycle progression. Recent work shows that association with neutrophils provides a proliferative advantage to CTCs, rendering them more competent in metastasis formation.
