Age-Dependent Increases in Apoptosis/Necrosis Ratios in Human Lymphocytes Exposed to Oxidative Stress

Abstract excerpt

Unlike apoptosis, mechanisms leading to necrosis are less well understood. Moreover, changes in necrosis as a function of age have not been studied in human lymphocytes. H(2)O(2)-induced death of peripheral lymphocytes (56 healthy donors, 24-95 years) was evaluated by flow cytometry and propidium iodide staining, caspase activation, DNA laddering, and electron microscopy. H(2)O(2)-induced stress was associated...
