Cellular immunity uses helper cells and killer cells to identify and destroy abnormal cells.
Tc cells are cytotoxic cells that are "effetors" of cellular immunity that carry out the attack on a foreign cells in other words Tc cells kill cells that have been infected by a foreign substance
t cells
Cancer cells and virus infected body cells can be killed before activation of adaptive immunity by natural killer cells. These may be noted as NK cells in literature.
There are many major problems associated with medicines that attack invading organisms and abnormal cells. One of these problems is that they also attack healthy cells.
If im correct, helper t-cells activate: b-cells that mark viruses and make them stick together, killer t-cells --which attack macrophages and infected cells, and memory b-cells, which remember how to stop viruses, this i believe is called active immunity
NK cell
they are in our bodies to attack and kill infected cells!
The Passive and Active Immunity's, why? Because they are immunity's that your body produces in response to a specific pathogen that has infected or is infecting your body.
