We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

Innate Intracellular Response to West Nile Virus @ University of Maryland College Pk Campus
[unreadable] DESCRIPTION (provided by applicant): The introduction of West Nile virus (WNV) in to the western hemisphere in 1999 and dramatic increase in both the rate and severity of disease in humans during subsequent transmission seasons, has resulted in its classification as an emerging pathogen of significant public health concern. In areas of Asia, the Middle East and Africa where WNV has been endemic for many years, infections are generally asymptomatic or associated with a mild childhood febrile illness. Recent WNV epidemics in developed countries in Europe and the United States have been associated with significantly higher rates of morbidity and mortality, indicating the emergence of a more pathogenic variant of the virus. Since its introduction into the United States WNV has rapidly spread and has now been detected in nearly every state in the continental U.S.A. The molecular mechanisms for the increase in pathogenesis of WNV are currently unknown but are likely to include novel virus-host interactions that allow the virus to overcome or evade the host innate and/or adaptive immune response. The goal of this research proposal is to define the interactions between a pathogenic WNV isolate and the host innate intracellular response. This proposal is designed to investigate the influence of the host interferon regulatory factor 3 (IRF-3), a central component of the host acute antiviral response, on WNV replication and pathogenesis. Two objectives have been utlined; 1) define the mechanism of IRF-3 signaling by WNV, and 2) define the effect of the IRF-3 pathway upon WNV replication. A more complete understanding of the innate intracellular response to WNV will aid in the development of novel therapeutic approaches to combat WNV infections. [unreadable] [unreadable]

West Nile Virus Interactions With the Innate Antiviral Response @ Univ of Maryland, College Park
DESCRIPTION (provided by applicant): The recent introduction of a highly pathogenic strains of West Nile Virus (WNV) into naive populations in Europe, Israel and the United States have resulted in epidemics with a marked increase in both the number of reported cases and the severity of disease compared to previous outbreaks. The increased virulence of the recently emerged strain of WNV is further complicated by the fact that antiviral therapies and vaccines are not currently available for use in humans. The molecular mechanisms for the increase in pathogenesis of WNV are currently unknown but are likely to include novel viral-host interactions that allow the virus to overcome or evade the host innate and/or adaptive immune response. Our preliminary studies indicate that pathogenic and nonpathogenic strains of WNV differ dramatically in their interactions with innate antiviral programs. This suggests that the comparison of the antiviral responses to pathogenic and nonpathogenic strains of WNV will provide key insights in viral factors involved in WNV- mediated pathogenesis. The specific aim of this proposal are (1) Determination of the pattern recognition receptors involved in detecting pathogenic and nonpathogenic strains of WNV (2) Identification of agonists of the innate antiviral response generated during WNV infection and (3) Determination of viral factors responsible for WNV virulence. A greater understanding of how strains with difference virulence phenotypes interact with the innate antiviral response will aid in the development of effective vaccines and therapeutic agents. PUBLIC HEALTH RELEVANCE: The ability of the cell to detect and respond to an invading pathogen is critical to its ability to defend itself against infections. This proposal will examine how cells detect West Nile virus infections and conversely the mechanisms the virus utilizes to control the cellular environment.
