Figure 1. Natural HIV-1 infection in primary human fetal astrocytes.
(A): Diagrammatic view of recombinant HIV-1 infectious molecular clone, NLENY1 showing yellow fluorescent protein (YFP) gene insertion. (B): Six-week-old human fetal astrocytes (HFA) were seeded in six-well culture plates and, two days later, infected with NLENY1 (1.0 μg/mL p24) for 2 h. Infected HFA shows green fluorescence on day 13 post-infection.
