Human Retrovirus Transmission and Pathogenesis. I am interested in the cellular and molecular mechanisms underlying virus transmission and the initiation of virus-induced diseases. After working for many years with experimental infections of mice with an RNA virus, lymphocytic choriomeningitis virus (LCMV), my research focus has shifted recently to the study of infections with the human retroviruses, human immunodeficiency virus type 1 (HIV-1) and human T-cell leukemia virus types I and II (HTLV-I and HTLV-II). These retroviruses can be transmitted either vertically or horizontally in human populations and we are beginning to define essential parameters, in both the donor and recipient of infectivity, that impact on the overall probability of transmission. Our experiments are based on primary human cell populations, human organ cultures, and body fluids from seropositive patients. Our goal is to develop manipulable experimental systems that duplicate the natural routes for virus transmission. More specifically, we are investigating the nature of HIV-1 infections in male reproductive tissue to understand variability in the shedding of HIV-1 infectivity in seminal fluid. In recipients, we are interested in defining the mechanisms whereby HIV-1 infectivity can breach epithelial barriers at mucosal surfaces and gain access to intraepithelial leukocytes for the initiation and expansion of primary infections. New insight into HIV transmission, with both cell-free and cell-associated HIV infectivity, will be invaluable in refining vaccine studies and may contribute significantly to the design of novel therapeutic agents to reduce the probability of HIV transmission.
'Wisc-e-sota', the 1st Joint UMN-UW Virology Training Grant Symposium will be held on Friday, Sepbember 20th, 2013 at the Uniiversity of Wisconsin-La Crosse, Cartwright Center. This is the inaugural collaborative symposium of the NIH T32-supported virology training programs at the University of Wisconsin-Madison and the University of Minnesota-Twin Cities. Talks and poster sessions will be presented by students, postdocs and faculty.
The 2013 IMV Symposium was held in May, 2013 and featured Vincent Racaniello as the Keynote Speaker as well as the recording of an episode of 'This Week in Virology'. Pictures from the IMV Symposium can be found on the IMV Facebook page and a videotape of the TWiV podcast can be viewed at www.twiv.tv
