Helper T cells are crucial for the immune response as they primarily function to assist other immune cells. They do this by releasing cytokines, which are signaling molecules that activate and regulate various immune components. Specifically, helper T cells enhance the activation of B cells, which are responsible for producing antibodies that target pathogens, as well as cytotoxic T cells, which directly kill infected or cancerous cells.

This supportive role is vital for orchestrating a robust and effective immune response. By coordinating the activity of other immune cells, helper T cells ensure a comprehensive attack on pathogens. Thus, their contribution is fundamental in bridging the adaptive immune response and ensuring that the body can respond effectively to infections and other immune challenges.
