Description of Research Expertise

My laboratory has a longstanding interest in human and simian immunodeficiency virus (HIV/SIV) molecular biology and pathogenesis and hepatitis C virus (HCV). Previous highlights of this work include the first molecular clones of HIV-1 (Shaw et al., Science 1984); recognition of the quasispecies nature of HIV-1 in vivo (Saag et al., Nature 1988); discovery of the dynamic and persistent nature of viral replication in vivo (Clark et al., N Engl J Med 1991; Piatak et al., Science 1993; Wei et al., Nature 1995); mechanisms of virus persistence in the face of evolving cellular and humoral immune responses (Borrow et al., Nature Medicine 1997; Wei et al., Nature 2003); and molecular identification and biological characterization of transmitted HIV-1 genomes and their progeny (Keele et al., Proc Natl Acad Sci USA 2008; Salazar et al., J Exp Med 2009; Li et al., PLoS Pathogens 2010). More recently, we have extended the work to SIV infection of rhesus macaque monkeys (Keele et al., J Exp Med 2009) and HCV infection of humans (Li et al., CROI 2011).

Current projects in the laboratory include:

1. Molecular studies of HIV-1 transmission, persistence and pathogenesis. This project area includes a molecular and biological analysis of HIV-1 viruses responsible for transmission and productive clinical infection resulting from heterosexual, homosexual and intravenous exposures and their subsequent evolution. The long-range goal is to develop effective vaccine strategies to prevent infection.

2. Molecular studies of SIV transmission, persistence and pathogenesis. This project area aims to develop more relevant SIV-rhesus macaque mucosal infection models and a clearer understanding of viral-host events responsible for transmission and productive clinical infection. A practical application of this work is in HIV/SIV vaccine design and assessment.

3. Molecular studies of HCV transmission, persistence and pathogenesis. This project area aims to leverage our recent discoveries in HIV-1 and SIV transmission biology based on single genome amplification and sequencing of plasma virion RNA to elucidate HCV transmission and early virus evolution. A major goal of this work will be to gain insights into immunopathogenic mechanisms of virus containment and persistence relevant to therapeutics and vaccine design. A second major goal is the development of novel strategies for identifying and characterizing full-length infectious molecular clones of HCV representing the seven major pandemic genotypes for use in in vitro and in vivo modeling and analyses.
