Type VI reaction according to the Gell and Coombs Classification . A phenomenon in which target cells, coated with antibody, are destroyed by specialized killer cells ( NK cells , Killer T-cells and macrophages ), which bear receptors for the Fc portion of the coating antibody (Fc receptors). These receptors allow the killer cells to bind to the anti-body-coated target. Eosinophils kill helminths (parasitic larvae infections) by ADCC.
