The document discusses T cell-mediated immunity, outlining the phases of T cell responses and the steps in T cell activation. It highlights the roles of receptors, ligands, and co-stimulation in activating CD8+ T cells and the development of CD4+ cells. Additionally, it mentions the migration of T cells in cell-mediated immune reactions and provides references for further reading.
