Guido Silvestri, MD, studies the pathogenesis of HIV infection and AIDS using the comparative nonhuman primate model of SIV infection in rhesus macaques and sooty mangabeys. In particular, the Silvestri lab is focused on the mechanisms by which SIV infection of natural hosts, such as the sooty mangabey, is not followed by CD4+ T cell depletion and AIDS despite chronic high levels of virus replication. By understanding the pathogenesis of the AIDS virus, Dr. Silvestri hopes to develop new immune-based therapies for HIV to be used in addition to antiretroviral therapy. In addition, Dr. Silvestri is interested in studying the mechanisms by which CD8+ T cells suppress virus replication, and to apply this knowledge to develop candidate AIDS vaccines that will generate effective CD8+ T cell responses against HIV/SIV.

As Chief of the Division of Microbiology and Immunology, Dr. Silvestri oversees the administrative functions of the division. This entails oversight of the administrative staff, approving grant submissions by division faculty and trainees, ensuring appropriate allocation of division resources and mentoring junior faculty.

Dr. Silvestri collaborates with a number of researchers at Yerkes, including Drs. Rama Amara, Mirko Paiardini and Mark Wilson.

In July 2013, Dr. Silvestri became Editor of the Journal of Virology. This appointment brings great responsibility in the oversight and publication of applicable research to the field of virology. Dr. Silvestri has served as the journal’s Associate Editor as well as Associate Editor of the Journal of Immunology and the Journal of Infectious Diseases. He is also a member of the Scientific Committee of the Conference on Retrovirus and Opportunistic Infections (CROI), is a frequent guest speaker and publishes regularly.
