Abstract excerpt
Immunoglobulin GM (γ marker) allotypes are strongly associated with neuroblastoma, but the mechanism is not known. One mechanism could involve antibody-dependent cell-mediated cytotoxicity (ADCC) of neuroblastoma cells. Using an ADCC inhibition assay, we show that IgG1 expressing GM 3+,1-,2- allotypes blocked all phenylalanine-expressing FcγRIIIa present on NK cells, resulting in total inhibition of anti-GD2...
