Antibody-dependent cell-mediated cytotoxicity to gliadin-coated cells with sera from children with coeliac disease.

• Antibody-dependent cell-mediated cytotoxicity (ADCC) has been suggested as a contributing immunological mechanism in the disease process of coeliac disease. In the present study, sera from coeliac children were examined for their capacity to mediate ADCC against gliadin-coated target cells. The ADCC-mediating efficacy of sera were tested using monocytes from healthy adults as effector cells and gliadin-coated erythrocytes from the same donor as targets. Using monocytes as effector cells, sera from children with active coeliac disease (untreated or challenged), demonstrated significantly higher ADCC-mediating capacity than sera from healthy and disease references as well as children with treated coeliac disease. A positive correlation was found between the ADCC-mediating capacity and serum IgG as well as IgA anti-gliadin antibody levels. The results suggest that an antibody-dependent monocyte/macrophage-induced cytotoxic reaction might be involved in the disease process of coeliac disease.
