"neutrophil"的定义和意义

What is a "neutrophil"?

A neutrophil is a type of white blood cell found in the human body, playing a vital role in the innate immune system. It is a highly mobile cell that quickly responds to sites of infection or injury. Neutrophils are capable of engulfing and destroying pathogens through phagocytosis, releasing antimicrobial substances, and forming neutrophil extracellular traps. Their efficient response helps to control infections and maintain tissue homeostasis.
