How does CD4 differ from CD8?
The basic difference between CD4 and CD8 T cells is that the CD4 T cells are the helper T cells that assist blood cells to produce an immune response, while the CD8 T cells are the cytotoxic T cells that cause cell death either by lysis or apoptosis. CD4 T cells produce cytokines to activate immune cells, while CD8 T cells destroy virus-infected cells and tumor cells.
