Which of the following is NOT a function of cell-mediated immunity?

Cell-mediated immunity primarily involves the activation and action of T cells, which are crucial in responding to intracellular pathogens and in mediating immune responses such as graft rejection and contact sensitivity. The function of directly destroying pathogens is not typically attributed to antibodies in cell-mediated immunity. Instead, antibodies operate mainly within the realm of humoral immunity, where they neutralize pathogens and mark them for destruction through various mechanisms, such as opsonization and complement activation. In contrast, other options correctly describe functions associated with cell-mediated immunity. Graft rejection involves T cell recognition of foreign tissues, while responses to contact sensitivity, like in the case of poison ivy, are mediated by T cells as part of their ability to respond to certain antigens. Viral and fungal immunity also heavily relies on cell-mediated responses, particularly involving cytotoxic T cells that target infected or abnormal cells. Thus, the option referring to direct destruction of pathogens by antibodies stands out as not being a function of cell-mediated immunity.
