Research Interests

Production and characterization of pathogenic human monoclonal auto- and alloantibodies

Research Summary

My laboratory is interested in characterizing the human immune response to auto- and alloantigens on a molecular level in order to understand more about human immune repertoire development. Our goal is to use this information to develop specific therapeutic agents that down-regulate immune responses in the settings of autoimmune disease such as immune hemolytic anemias and thrombocytopenias, transfusion reactions, hemolytic disease of the newborn, and acute rejection of solid organ allografts.
To approach these problems experimentally, we have combined Fab/phage-display technology with a novel cell-surface panning method to isolate large arrays of clinically significant human monoclonal antibodies from individual patients. This approach has enabled us to study the genetic and immunological properties of pathogenic auto- and alloantibodies.

Description of Itmat Expertise

Dr. Siegel's research focuses on the study of the molecular genetics of human auto- and alloantibodies responsible for blood cell-related disorders such as immune cytopenias (ITP, AIHA, TTP), hemolytic transfusion reactions, and hemolytic disease of the newborn. The Siegel laboratory has developed several phage display-related technologies for the cloning of human immune repertoires and the production of human monoclonal antibodies. These studies have led to the development of novel diagnostic reagents and antibodies with therapeutic potential.
