Keywords: signal transduction, cancer, transfusion medicine, HIV pathogenesis
Dr. Branch's current interests can be broken down into 4 main areas:
  • Signaling involving c-Src
  • Signaling in HIV/AIDS pathogenesis and disease resistance
  • Studies of SHP-1 tyrosine phosphatase in malignancies
  • Mechanism of intravenous immunoglobulin (IVIG) effect in autoimmune inflammatory diseases
Current projects include:
  • The function of pp60c-src and Pyk2 in HIV infection 
  • The role of signaling through the VPAC family of neuroendocrine receptors on HIV/AIDS infection and resistance to infection 
  • Drug discovery for small molecular weight molecules that block HIV fusion 
  • Identification of novel treatment modalities for HIV/AIDS 
  • The signaling pathways used by HIV for its early stages of its life cycle 
  • The mechanism of IVIG treatment for autoimmune inflammatory diseases 
  • Drug discovery for small molecular weight molecules that inhibit phagocytosis 
  • The mechanism of anti-D immune prophylaxis and treatment of idiopathic thrombocytopenic purpura
  • Drug discovery for alternatives to IVIG
IVIG regulates the survival of human but not mouse neutrophils.
