Understanding Diseases to Optimize Transfusion Practice

Dr. Branch’s research aims to understand the pathogenesis and functioning of cells in various diseases that require blood transfusion products and related biologics. In particular, Dr. Branch studies mononuclear phagocytes to understand and inhibit the phagocytosis function of these cells in autoimmune diseases and, using animal models of autoimmune diseases, the mechanism of amelioration by intravenous immunoglobulin (IVIg) therapies.

Why is this important?

Understanding the cellular and molecular mechanisms associated with autoimmune diseases and mechanism of IVIg therapy should provide new treatment strategies.

Signaling in HIV/AIDS Pathogenesis and Disease Resistance and Investigation of Novel Therapies

Dr. Branch is applying his expertise in cell signaling to the study of HIV and has identified new targets for HIV/ Acquired Immune Deficiency Syndrome (AIDS) therapy.

Why is this important?

Understanding the signaling pathways used by HIV and identifying novel ways to interfere with viral signaling could lead to better treatment options for patients with HIV/AIDS and other viral diseases.

Signal Transduction and Signaling Abnormalities in Malignancies

Understanding abnormal cell signaling in cancers and proliferative diseases helps to shed light on how these diseases develop and progress.

Why is this important?

This research aims to develop new strategies to treat cancers and proliferative diseases. Better treatment options for cancer patients could reduce the transfusion needs of these patients. In addition, work done on the role of c-Src in B-cell proliferation could be used to increase the production of monoclonal antibodies used in transfusion services for blood antigen testing.
