210 Low Post-Seroconversion CD4 Count and Rapid Decrease of CD4 Density Identify HIV+ Fast Progressors

Background: CD4 expression in HIV replication is paradoxical: HIV entry requires high cell-surface CD4 densities, but replication requires CD4 down-modulation. However, is CD4 density in HIV+ patients affected over time? Do changes in CD4 density correlate with disease progression? Here, we examined... View More
