Research Focus

According to the latest statistics published by the UNAIDS/WHO in December 2007, 33.2 million people were living with the Human Immunodeficiency Virus (HIV). In 2007, 2.1 million people died as a result of the acquired Immunodeficiency Syndrome (AIDS). Although antiretroviral drugs have had a dramatically beneficial impact on HIV-infected individuals who have access to treatment, they have had a negligible impact on the global epidemic. Therapies for retroviral infections in humans now used in clinical practice have limitations in that they often only shorten the duration of disease symptoms or fail to completely eradicate the virus with viral replication and disease recurring after discontinuation of the drug therapy. Additionally, the emergence of HIV variants with drug-resistance is an ongoing clinical problem. Clearly having a larger repertoire of therapeutic agents would be beneficial for combating the HIV epidemic.

Retroviruses, due to their limited genome size and content, require the assistance of multiple host cellular proteins at each step in their elaborate replication cycle. Host cells, in response, have evolved many mechanisms for inhibiting viral replication. We have taken a general approach to identify the molecular interactions occurring within a cell that are critical for viral replication, or genes that have evolved in mammalian cells to block viral replication. The discovery of cellular factors involved in retroviral replication and an increased knowledge of their mode of action may lead to important antiviral approaches in clinical settings as one could block the modified use without affecting cell viability.
