    West Nile virus (WNV) is a highly virulent re-emerging human pathogen and the leading cause of arthropod-borne encephalitis in the US.  Neither vaccines nor antiviral or immunomodulator therapies are available for WNV, and new concepts based on precise understanding of molecular pathogenesis are needed.  WNV causes meningitis and multifocal encephalitis in both human disease and mouse models, characterized by the accumulation of leukocytes, including monocytes and T cells, in the brain.  The major research goals of my laboratory are to 1) understand leukocyte trafficking events, both at the molecular and cellular level, as they relate to host defense against WNV; 2) understand host genetic susceptibility to WNV; and 3) develop new models to evaluate WNV and otherh flavivirus infection.  The primary tools used to evaluate these questions are a well-established mouse model of WNV infection, samples acquired from WNV-infected individuals, and an ex vivo model of WNV infection in human lymphoid tissue.  A combination of these approaches will provide a comprehensive understanding of WNV pathogenesis and virus-host interactions.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Lim did not report having any of the following types of financial relationships with industry during 2014 and/or 2015: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
