Figure 4From: Single amino acid change in gp41 region of HIV-1 alters bystander apoptosis and CD4 decline in humanized miceV38E mutant replicates in Mice without reverting to WT. (A) Viruses were recovered from mice sacrificed at the 8 weeks post infection by coculturing PHA and IL-2-activated PBMCs with SupT1 cells. Supernatants were harvested at different time points and RT activity determined. (B) Photomicrographs of cultures in (A) on day 10 is shown. Magnification = 10X. (C) Sequence analysis of proviral gp41 from WT and V38E infected mice.Back to article page
