Developing treatment and prevention strategies for respiratory syncytial virus: Protecting the most vulnerable
John DeVincenzo is developing vaccines and antivirals for respiratory syncytial virus infection, from initial conception through proof-of-concept clinical trials, carried out through several academic, foundation, and industry pathways. In 2014 he published the first evidence that treating an established RSV infection in humans can lower the viral load and result in reduced disease. He has since demonstrated proof of therapeutic efficacy for five different antivirals with different modes of delivery and mechanisms of action. He has conducted numerous clinical trials defining the role of prevention and therapeutic applications of monoclonal antibodies targeting RSV in infants and the immune-suppressed. He received his MD from Vanderbilt Medical School. He is a professor of pediatrics and of molecular sciences at the University of Tennessee School of Medicine and is the medical director of the Le Bonheur Children’s Hospital virology laboratory and the molecular diagnostics laboratory.
Alphavirus receptors: Identification, characterization, and possible drug targeting
Mike Diamond’s laboratory studies the molecular basis of pathogenesis of emerging RNA viral diseases, focusing on the interface between infection and host immunity. He has identified many of the key innate and adaptive immune system components that define protection against flaviviruses, and the viral genes that antagonize this response. His laboratory made a seminal discovery by identifying a novel pathogen-associated molecular pattern (lack of 2'-O methylation on the 5' viral RNA cap) and mechanism of innate immune restriction through IFIT1 proteins. His group has used genome-wide screening to identify host factors required by viruses, including a novel entry receptor for multiple alphaviruses, which has led to the development of antiviral therapeutic antibodies and vaccines against both flaviviruses and alphaviruses. He received his MD and PhD degrees from Harvard Medical School and Harvard University. He is the Herbert S. Gasser Professor of Medicine, Molecular Microbiology, Pathology & Immunology at the Washington University School of Medicine.
