Luis J. Montaner, D.V.M., M.Sc., D.Phil.
Associate Professor, Immunology Program
The Wistar Institute
Philadelphia, PA

Luis MontanerDr. Luis Montaner obtained his D.V.M., Veterinary Medicine at Kansas State University in 1989, and his Ph.D. degree in Experimental Pathology at University of Oxford, Oxford, UK in 1995. His dissertation was entitled ÒCytokine Regulation of HIV-1 in Macrophages and Lymphocytes in vitroÓ .In 1995 became an Assistant Professor at The Wistar Institute, Philadelphia, PA and in 2007 was promoted to Professor in the same institute. He also holds a joint appointment with the Department of Medicine at the University of Pennsylvania Medical School. Department of Medicine. He lectures on the Immunology and Frontiers of Medicine courses at the University of Pennsylvania Medical School.

Dr. Montaner's group at the Wistar Institute is funded by RO1 grants from the NIH and other sources and his groups main research interests are the mechanisms of disease in HIV-1 infection and novel approaches to augment immune function by combining virological and immune-based research on patient-derived material as well as by using laboratory models of virus infection. The work is focused on 1) regulation of innate immunity, with emphasis on the effects of HIV infections and HAART on dendritic cells, macrophages, and Natural Killer cells 2) identifying new mechanisms of immunodeficiency, such as impaired IL-12 secretion, and discovering new approaches to reverse them through immunotherapy, 3) exploring new therapy management practices, such as structured therapy interruptions, and 4) understanding the relationship between immune antiviral responses and control of HIV-1 infection.

Dr. Montaner is a member of the Board of Directors of the Community-based AIDS Clinical Trials Group of the Philadelphia FIGHT (a community-based HIV-1 clinical research organization), a member of the Scientific advisory boards of Foundation for AIDS and Immune Research (FAIR), Los Angeles, CA and of Aventis-Pasteur, and an elected Councilor of the Society of Leukocyte Biology, FASEB (term 2006-2009)

Dr. Montaner is a south after national and international lecturer, and he has published in excess of 70 manuscripts in highly prestigious peer reviewed journals such as the Proceedings of the National Academy of Sciences Journal of Immunology, the Journal of Virology, the Journal of Infectious Diseases, Blood, and the Journal of Biological Chemistry.
