So our cell mediated immunity is very effective against cells that have been infected by these different types of pathogens. So these are the major differences between the antibody mediated immunity and the cell mediated immunity. But these two different divisions must actually work together to carry out that same function. They cannot exist by themselves. For example these B lymphocytes need the helper T cells to actually differentiate and produce our antibodies. And the cell mediated immunity means these antibodies to actually function properly.
