NEUTROPHIL INFILTRATION Meaning and
Definition
-
Neutrophil infiltration refers to the process in which neutrophils, a type of white blood cell, migrate from the bloodstream into the surrounding tissues in response to an inflammatory stimulus or infection. Neutrophils are a crucial component of the innate immune system and are the first responders to sites of injury or infection.
The infiltration of neutrophils is regulated by a complex series of events. Upon recognition of signals released by damaged cells or invading pathogens, neutrophils are activated and undergo a process called chemotaxis, in which they move towards the site of inflammation. This is facilitated by the binding of neutrophils to adhesion molecules on the endothelial cells lining the blood vessels near the inflamed area.
Once the neutrophils have infiltrated the tissues, they play a central role in the immune response. Their primary function is to eliminate pathogens through phagocytosis, a process in which they engulf and destroy the invading microorganisms. Neutrophils also release antimicrobial substances and enzymes that help to break down and remove cellular debris, contributing to the resolution of inflammation.
Neutrophil infiltration is a characteristic feature of many inflammatory disorders, such as acute infections, autoimmune diseases, and chronic inflammatory conditions. Monitoring the extent of neutrophil infiltration can be important in diagnosing and assessing the severity of these diseases, as well as in evaluating the effectiveness of treatments.

Etymology of NEUTROPHIL INFILTRATION
The word "neutrophil" comes from the Greek roots "neutrós" meaning "neuter" or "neutral", and "phílos" meaning "loving" or "friend". The term refers to a type of white blood cell called "neutrophils" that are known for their neutral staining properties when viewed under a microscope.
The word "infiltration" has Latin roots, derived from the Latin word "infiltrare", meaning "to filter into". In the context of medicine, it refers to the process of cells or substances penetrating or seeping into tissues, organs, or spaces where they are not typically found.
Thus, "neutrophil infiltration" refers to the presence and movement of neutrophils into a tissue or organ, often as part of an immune response to combat infection, inflammation, or injury.
