HELPER CELLS Meaning and
Definition
-
Helper cells, also known as T-helper cells, are a vital component of the immune system that play a crucial role in the adaptive immune response. These specialized white blood cells are a type of lymphocyte and are classified as part of the T-cell subset. Helper cells receive signals from other immune cells, such as antigen-presenting cells, and provide assistance in coordinating and enhancing immune responses against pathogens.
The main function of helper cells is to recognize specific antigens presented by antigen-presenting cells. This recognition occurs through the interaction of T-cell receptors and major histocompatibility complex (MHC) molecules on the surface of antigen-presenting cells. By recognizing these antigens, helper cells become activated and start to release chemical messengers called cytokines.
Cytokines secreted by helper cells have various functions, including activating other immune cells such as B-cells and cytotoxic T-cells. They also contribute to the regulation of immune responses by promoting the proliferation and differentiation of specific immune cell types. Furthermore, helper cells are involved in the generation of immunological memory, enabling the immune system to respond more effectively upon re-exposure to a previously encountered pathogen.
In summary, helper cells are an essential component of the adaptive immune system. Their ability to coordinate and enhance immune responses through the release of cytokines makes them crucial for the clearance of pathogens and the establishment of long-term immune protection.

Etymology of HELPER CELLS
The word "helper cells" does not have a specific etymology since it is a general term used in biology and immunology. However, we can analyze the individual terms to understand their origins:
1. Helper: The word "helper" comes from the Old English word "helpere" which means "one who helps or gives aid". It can be traced back to the Proto-Germanic word "helparō" and the Proto-Indo-European root "kelb" meaning "to help" or "to support".
2. Cells: The term "cells" has its origins in Latin. It stems from the Latin word "cellula" meaning "small room" or "small compartment". This word came from "cella" which means "storeroom" or "chamber".
