Verified step by step guidance

1. Understand the role of T cells in the immune system: T cells are a type of lymphocyte that play a central role in cell-mediated immunity.
2. Recognize the different types of T cells: Helper T cells (CD4+) and Cytotoxic T cells (CD8+) are the main types, each with distinct functions.
3. Helper T cells coordinate the immune response by releasing cytokines: Cytokines are signaling molecules that help activate and direct other immune cells, such as B cells and macrophages.
4. Cytotoxic T cells directly attack and destroy infected cells: They recognize and bind to infected cells, releasing substances that lead to the destruction of these cells.
5. Clarify the misconception: T cells do not produce antibodies; this is the role of B cells. T cells primarily function through cytokine release and direct cell-mediated attack.
