Figure 1

The infectivity mediated by the 42 or 48-month viral isolates was measured in U373- MAGI target cells expressing CD4 and either CCR5 or CXCR4. Infection with virus SF128A, NL4-3 or 89.6 served as controls for CCR5, CXCR4 or CCR5/CXCR4 usage virus, respectively. The results are representative of two independent experiments, and the error bars represent standard deviations.
