Current Concepts in AIDS Pathogenesis: Insights from the SIV/Macaque Model

Abstract

The pathogenesis of AIDS has proven to be quite complex and dynamic, with most of the critical events (e.g., transmission, CD4+ T cell destruction) occurring in tissues that are not easily accessible for analysis. In addition, although the disease can progress over years, many critical events happen within the first few weeks of infection, when most patients are unaware that they are infected. The nonhuman primate model of AIDS has been used extensively to fill these gaps in our understanding of AIDS pathogenesis.
