title: Antibody-dependent cellular cytotoxicity of mononuclear cells from asthmatics tested in three in vitro assays.
abstract: Using the chicken red blood cell assay, the human Chang liver cell assay, and a lymphoblastoid cell assay, mononuclear cells from asthmatics and normals were tested for antibody-dependent cellular cytotoxicity (ADCC) capacity. Mononuclear cell preparations from perennial nonallergic asthmatics with a history of asthma associated with viral infections had a reduced ADCC capacity in the chicken red blood cell assay, an increased ADCC capacity in the Chang liver cell assay, and normal ADCC capacity in the lymphoblastoid cell assay. The data also suggested that perennial nonallergic asthmatics had increased percentages of surface IgG-negative lymphocytes in the peripheral blood when compared to normals.
