TH CELLS Meaning and
Definition
-
Th cells, also known as T helper cells, are a type of white blood cell that play a crucial role in regulating the immune response. They are a subset of T lymphocytes and are involved in activating and coordinating various immune cells to defend the body against infections and other foreign substances.
Th cells are primarily responsible for recognizing antigens, which are foreign molecules that can elicit an immune response. When an antigen is detected, Th cells become activated and release chemical messengers called cytokines. These cytokines serve as signals to direct other immune cells, such as B cells and cytotoxic T cells, to eliminate the antigen.
There are different subtypes of Th cells, differentiated based on the specific cytokines they produce. For instance, Th1 cells mainly produce interferon-gamma, which helps enhance cellular immunity to combat intracellular pathogens like viruses. Th2 cells, on the other hand, secrete cytokines such as interleukins-4, -5, and -13, which support humoral immunity and play a role in allergic reactions and defense against parasites.
Th cells also play a critical role in immune memory. After an initial exposure to an antigen, some Th cells differentiate into memory Th cells, which can quickly respond to subsequent exposures. This immune memory helps mount a faster and more efficient immune response upon re-encounter with the same antigen, leading to improved protection against infections.
Overall, Th cells are central players in the adaptive immune system, orchestrating and coordinating immune responses to various threats to maintain the body's health and well-being.

Etymology of TH CELLS
The term Th Cells stands for T-helper cells, which are a type of lymphocyte. The etymology of the term is as follows:
- T refers to the thymus, which is the organ where T-cells mature.
- helper signifies the role of these cells in helping coordinate immune responses and activating other immune cells.
- Cells simply refers to these specialized lymphocytes.
Therefore, the word Th Cells is a shortened form derived from the full term T-helper cells.
