title: Functional variation of HIV-1 Rev Response Element in a longitudinally studied cohort.
abstract: We showed previously that HIV-1 Rev Response Element (RRE) contains a certain degree of structural variation, and in a set of limited samples, RRE from HIV-1 natural isolates were found to have functional variability. The significance of the RRE heterogeneity is addressed further by analyzing the functional variation of RREs in a longitudinal cohort. While the RRE activity at early time points was not a good predictor of disease outcome, the RRE activity at late time points was correlated with rates of CD4+ count decline. These data suggest that RRE heterogeneity may be important in viral pathogenesis and disease progression.
