what are characteristics of neutrophils?
Neutrophils are the most abundant type of white blood cells in the body, making up 70% of all leukocytes (white blood cells). These cells play an important role in the immune system. When a pathogen (disease-causing microorganism) enters the body, neutrophils are the first phagocytes to attack the invader.
About 45% of the neutrophil cytosolic protein is made of migration inhibitory factor-related proteins (MRPs), MRP-8 and MRP-14. Neutrophils contain a large amount of glycogen (a stored form of glucose) in the cytoplasm. The glycogen provides neutrophils with energy.
