IMMUNOLOGIC SURVEILLANCES Meaning and
Definition
-
Immunologic surveillance refers to the continuous monitoring and recognition of foreign or abnormal cells and molecules by the immune system within the body. It is a crucial aspect of the immune response that helps to detect and eliminate potentially harmful cells, such as pathogens or cancerous cells.
The immune system consists of various specialized cells, tissues, and molecules that work together to protect the body from diseases and maintain its overall health. Immunologic surveillance plays a fundamental role in this process by constantly surveying and identifying any deviations from normal cell functioning.
When foreign or abnormal cells, such as cancer cells or infected cells, appear in the body, they may display specific markers (antigens) that help the immune system recognize them as targets for destruction. Immune cells like natural killer (NK) cells, cytotoxic T lymphocytes, macrophages, and dendritic cells are actively involved in identifying and eliminating these abnormal cells through various mechanisms such as cell lysis or phagocytosis.
Furthermore, immunologic surveillance also includes the recognition and elimination of potentially harmful molecules, such as toxins or allergens, that may enter the body.
Overall, immunologic surveillance is a vital process that allows the immune system to constantly monitor and combat threats to the body's health, contributing significantly to the body's defense against infections, cancer, and other diseases.

Etymology of IMMUNOLOGIC SURVEILLANCES
The word "immunologic" is derived from the Greek word "immunis", meaning "exempt" or "free", and thence from "immunologia", which literally translates to "the study of immunity" in Latin. The term "surveillance" comes from the French word "surveiller", meaning "to watch over". Therefore, "immunologic surveillance" essentially refers to the process by which the immune system monitors, detects, and eliminates foreign substances, such as pathogens or abnormal cells, in order to maintain the body's health and protect against disease.
