Fig. 1.From: Critical Role of Nitric Oxide During the Apoptosis of Peripheral Blood Leukocytes from Patients with AIDSEffect of NO on PBMC apoptosis. Cells from patients with AIDS or healthy seronegative donors were incubated (106/ml) in medium alone (None) or in the presence of 100 µM SNAP. The percentage of surviving (propidium iodide−) non-apoptotic (annexine−) cells (compared to seeded cells, 100%) was obtained. Each circle represents a different donor. Thick bars show means.Back to article page
