Cell-mediated immunity is a crucial component of the adaptive immune response that relies on the activation of T cells to combat intracellular pathogens and cancer cells. This form of immunity is distinct from humoral immunity, as it focuses on direct cell-to-cell interactions rather than the production of antibodies. Through the actions of various T cell subsets, such as cytotoxic T cells and helper T cells, cell-mediated immunity plays a vital role in protecting the body from infections and maintaining immunological memory.
