What role do helper T cells play in the immune system?

Helper T cells play a crucial role in the immune system by assisting in the activation and coordination of other immune cells. Their primary function is to facilitate the immune response by releasing cytokines, which are signaling molecules that help to activate B cells (which produce antibodies) and cytotoxic T cells (which directly kill infected cells). Through this activation process, helper T cells enhance the immune response against pathogens, ensuring that the body can effectively combat infections.

In this context, although other immune cells contribute to various aspects of the immune response, helper T cells are specifically known for being essential in orchestrating and regulating these responses, making their role distinctly focused on activation rather than direct clearance or antibody production. Specifically, the immune system relies on these interactions, as without helper T cells, the effectiveness of the immune response would be significantly diminished.
