title: Identification of the target platelet glycoprotein in autoimmune thrombocytopenia occurring after allogeneic bone marrow transplantation.
abstract: We report the case of a patient who developed autoimmune thrombocytopenia after allogeneic bone marrow transplantation from her HLA-identical sister. An IgG autoantibody was detected that bound to the platelet glycoprotein IIb/IIIa and to the HLA class I proteins. Immunoprecipitation studies with radiolabeled platelets revealed additional antibody binding sites on proteins of 214 kDa molecular weight under nonreduced conditions and 65 and 56 kDa molecular weight under reduced conditions.
