سمية الخلية المعتمدة على الأجسام المضادة بوساطة الخلية
الأجسام المضادة (antibody-dependent cell-mediated cytotoxicity ADCC)، ويشار إليها أيضاً بإسم antibody-dependent cellular cytotoxicity، هي آلية cell-mediated immune defense whereby an effector cell of the immune system actively lyses a target cell, whose membrane-surface antigens have been bound by specific antibodies.[1] It is one of the mechanisms through which antibodies, as part of the humoral immune response, can act to limit and contain infection.[2]
ADCC is independent of the immune complement system that also lyses targets but does not require any other cell. ADCC requires an effector cell which classically is known to be natural killer (NK) cells that typically interact with IgG antibodies.[3] However, macrophages, neutrophils and eosinophils can also mediate ADCC, such as eosinophils killing certain parasitic worms known as helminths via IgE antibodies.[4]
ADCC is part of the adaptive immune response due to its dependence on a prior antibody response. The coating of target cells with antibodies is sometimes referred to as opsonization.
