Answer:
The name given to the type of nk-cell killing that is dependent on ligation through an fc receptor known as Antibody-dependent Cell-mediated Cytotoxicity (ADCC).
Step-by-step explanation:
Antibody-dependent Cell-mediated Cytotoxicity (ADCC) a crucial immune system defense mechanism that fights infections and malignant cells.
- The primary goal of ADCC is to defend an organism against (perhaps dangerous) cells; target cells are coated with antibodies so that effector cells can identify them. Thus, they seek to kill the intended cells.
- ADCC is triggered by the identification of dangerous cells, to which particular antigens bind to make the target cells visible for effector cells, who subsequently try to kill them.
- Effector cells target pathogenic cells that have been identified and coated by certain antibodies. Target cells will be captured by natural killer cells, which will then provide cytotoxic agents before lysing the cells into harmless fragments.
