Cell-mediated immunity consists of a set of immune phenomena distinct from antibody-mediated immunity. Several features distinguish the humoral and cellular arms of the immune system. Specifically, cell-mediated immunity is mediated by T cells and monocytic cells and requires either intact cells to carry out their immune functions by direct cell-to-cell contact or acts through production of soluble factors, or cytokines that control and/or regulate specific immunologic functions.
1. The T helper 1/T helper 2 paradigm
2. T helper 1 and T helper 2 cells exhibit functionally distinct characteristics.
3. T helper 1 and T helper 2 cells regulate cellular function
4. Phagocyte-dependent host responses
5. Both CD4+ and CD8+ cells
6. Histocompatibility
