Neutrophils (also known as polymorphonuclear leukocytes) are a type of white blood cell, making up 40% to 70% of all white blood cells in humans. They act as an essential part of the innate immune system in our body.

Neutrophils are a type of phagocyte normally found in the bloodstream. During the beginning, acute  phase of inflammation, particularly as a result of bacterial infection, environmental exposure, and some cancers, neutrophils are one of the first responders of inflammatory cells to migrate toward the site of inflammation.

As a lab based in the Department of Pharmacology, College of Korean Medicine, we search for herbal medicine and natural products which can regulate neutrophil functions.
