Neutrophils

Neutrophils or polymorphonuclear leukocytes (PMNs) are the primary types of white blood cells in humans. They stand out with their distinct segmented nuclei and granules. They are the first responders against all infectious pathogens. As the vanguard of the innate arm of immunity, neutrophils phagocytose, destroy, and digest the pathogen cells - a process that is thought to be non-specific and straightforward. They are also important modulators of inflammation.
