CELLULAR INFILTRATION Meaning and
Definition
-
Cellular infiltration refers to the accumulation or presence of an excessive number of cells within tissues or organs, usually as part of an immune response or pathological process. It involves the migration of immune cells, such as lymphocytes, macrophages, neutrophils, or eosinophils, into the affected tissue or organ. The infiltrating cells play a key role in defending the body against various stimuli, such as infection, injury, inflammation, or tumors.
The process of cellular infiltration begins when immune cells are attracted to specific signals or chemical substances released by damaged or infected tissues. This chemotactic stimulation triggers the migration of immune cells from blood vessels into the affected area. The infiltrating cells then participate in various immune activities, including phagocytosis, release of inflammatory mediators, secretion of cytokines, and activation of other immune cells.
Cellular infiltration can be seen in various medical conditions, such as infections, autoimmune diseases, allergic reactions, chronic inflammation, and even cancer. It can be observed histologically using staining techniques to identify and quantify the type and extent of infiltrating cells.
Understanding cellular infiltration is crucial in diagnostic pathology, as the presence and distribution of infiltrating cells can provide valuable information about the underlying disease process. Additionally, cellular infiltration can serve as a target for therapeutic interventions by modulating immune cell migration or function to control inflammation or treat various diseases.

Etymology of CELLULAR INFILTRATION
The term "cellular infiltration" is composed of two main elements: "cellular" and "infiltration".
1. Cellular: The word "cellular" comes from the Latin word "cellula", which means "small room or enclosure". In English, it is related to the Latin "cella", meaning "small room". The term "cellular" is commonly used to refer to something related to cells, which are the basic structural and functional units of living organisms.
2. Infiltration: The word "infiltration" originates from the Latin word "infiltrare", which is a combination of "in" (meaning "into") and "filtrare" (meaning "to filter"). In English, "infiltration" refers to the process of infiltrating or penetrating into something gradually or stealthily.
