Donald R Branch, PhD

Dr. Branch's current interests can be broken down into 6 main areas:

  • Signalling involving tyrosine kinases
  • Signalling in HIV/AIDS pathogenesis and disease resistance
  • Mechanism of intravenous immunoglobulin (IVIG) effect in autoimmune inflammatory diseases
  • Replacement of high-dose IVIg in autoimmune/inflammatory diseases
  • Mechanism(s) of action of recombinant Fc multimers to ameliorate rheumatoid arthritis in a mouse model
  • Studies using monocytes and M1/M2 macrophages to understand red blood cell destruction in diseases involving eyrptosis and hyperhemolysis

Current projects include:

  • The function of Ableson tyrosine kinases in HIV infection
  • The function of spleen tyrosine kinase (Syk)-family in HIV infection
  • The role of signalling through the VPAC family of neuroendocrine receptors on HIV infection and resistance to infection
  • Identification of novel treatment modalities for HIV/AIDS
  • The mechanism of IVIG and recombinant Fc multimer treatment for amelioration of autoimmune inflammatory diseases
  • Drug discovery for small molecular weight molecules that inhibit phagocytosis
  • Use of in vitro phagocytosis assays to aid in predicting probability of hemolysis in patients requiring blood transfusion
