What is the typical role of TH cells in the immune response?

The typical role of TH (T-helper) cells in the immune response is to coordinate the activity of other immune cells. These cells are a subset of T cells that play a crucial role in the adaptive immune system. They do not directly kill infected cells, produce antibodies, or act as phagocytes.

Instead, T-helper cells regulate and enhance the immune responses by releasing cytokines, which are signaling molecules that help activate and direct other immune cells, such as B cells and cytotoxic T cells. By promoting the proliferation and differentiation of B cells, TH cells facilitate the production of antibodies. Additionally, their interactions with cytotoxic T cells assist in the killing of infected or cancerous cells. This coordination is essential for a well-organized and effective immune response, ensuring that the immune system can respond appropriately to infections and other health threats.
