Despite the extraordinary advances in HIV research over the past 30 years, the AIDS pandemic remains one of the greatest scientific challenges in the world. The main focus of the Viral Pathogenesis Section (VPS) is to study the pathogenesis of HIV-1/AIDS and to use this knowledge to devise innovative treatment and vaccine strategies. A primary area of interest is the elucidation of the structure-function relationships within the HIV-1 envelope, with the aim of identifying conserved functional regions and elucidating the structural basis of immune evasion, one of the main obstacles to vaccine development. This knowledge guides the VPS efforts to rationally engineer new vaccine immunogens capable of eliciting the production of broadly neutralizing antibodies.
Other research topics include the study of endogenous immune modulators that regulate HIV-1 transmission, replication, and pathogenesis, including antiviral chemokines, interleukin-7, and integrin α4β7. The VPS uses a comprehensive research approach that combines classic immunology and virology with state-of-the-art post-genomic technologies and pre-clinical in vivo studies in nonhuman primates.
Dr. Lusso received his M.D., magna cum laude, from the University of Turin and his Ph.D. from the Ministry of Scientific and Technologic Research, Rome, Italy. He is a board-certified specialist in internal medicine and in infectious diseases. He came to NIH for the first time in 1986 to work in the Laboratory of Tumor Cell Biology under Dr. Robert C. Gallo at the National Cancer Institute. He returned to Italy in 1994, where he created the Laboratory of Human Virology at the San Raffaele Scientific Institute in Milan and became associate professor of infectious diseases at the University of Cagliari. In 2006, he again joined NIH, where he became chief of the Viral Pathogenesis Section in the Laboratory of Immunoregulation. He is an executive editor of Current HIV Research and a member of the editorial board of several other journals. He is an elected member of the European Molecular Biology Organization (EMBO).
