Figure 2From: Apoptosis resistance in HIV-1 persistently-infected cells is independent of active viral replication and involves modulation of the apoptotic mitochondrial pathwayApoptosis resistance is independent of the magnitude of viral replication. A) Jurkat and J1.1 cells were incubated in the presence or absence of 1000 U/ml TNF-α for 48 h, and then treated with 10 μM H2O2 or 0.1 μM STS. The percentages of annexin-V+, PI- or PI+ cells are shown. B) U937 and U1 cells were incubated in the presence or absence of 100 ng/ml PMA for 24 h, and then exposed to 10 μM H2O2 or 0.1 μM STS. The percentages of annexin-V+, PI- or PI+ cells are shown.Back to article page
