| Abstract | Neutrophils represent the first line of defense against bacterial and fungal pathogens. Indeed, patients with inherited or acquired qualitative and quantitative neutrophil defects are at high risk for developing bacterial and fungal infections and suffering adverse outcomes from these infections. Therefore, research aiming at defining the molecular factors that modulate neutrophil effector function under homeostatic conditions and during infection is essential for devising strategies to augment neutrophil function and improve the outcomes of infected individuals. This article describes reproducible density-gradient-centrifugation-based as well as positive and negative immunomagnetic selection protocols that can be applied in any laboratory to harvest large numbers of highly enriched and highly viable neutrophils from the bone marrow of mice. In another protocol, we also present a method that combines gentle enzymatic tissue digestion with a positive immunomagnetic selection technique or fluorescence-activated cell sorting (FACS) to harvest highly pure and highly viable preparations of neutrophils directly from mouse tissues such as the kidney, the liver, or the spleen. Mouse neutrophils isolated by these protocols can be used to examine several aspects of cellular function ex vivo, including pathogen binding, phagocytosis, and killing, neutrophil chemotaxis, oxidative burst, degranulation, and cytokine production, and for performing neutrophil adoptive transfer experiments. © 2023 Wiley Periodicals LLC.
