Neutrophils, the body's most abundant type of white blood cells, have long been regarded as first responders that kill fungi, bacteria, and other pathogens. In a study published in Nature Immunology, Case Western Reserve researchers explain that they have found the mechanism of action of a newly discovered population of neutrophils.
