Immune Disorders of the Blood Blood cells are targeted for destruction by antibodies in many clinically important disorders. Some of these conditions have an autoimmune etiology; others are caused by alloantibodies, isoantibodies or drug sensitivity. We are engaged in studies to improve the understanding of this family of disorders. Areas of current research interest are the drug-immune cytopenias, neonatal alloimmune thrombocytopenia and immune disorders that affect neutrophils. Current studies are aimed at characterizing the basis for the aberrant immune response that leads to these conditions, mechanism(s) by which drugs promote binding of drug-induced antibodies to their targets and molecular characteristics of antigens recognized by pathogenic antibodies. We expect these studies will lead to improved methods to diagnose, treat and prevent hematologic diseases associated with autoimmunity, alloimmunity and drug sensitivity.
