Figure 8From: Legionella pneumophila infection induces programmed cell death, caspase activation, and release of high-mobility group box 1 protein in A549 alveolar epithelial cells: inhibition by methyl prednisoloneCaspase activity inL. pneumophila-infected A549 cells detected by western blotting. Cells treated as for the colorimetric assay were subjected to western blotting. Cleavage activations of caspase 8, 9, and poly (ADP-ribose) polymerase (PARP; natural substrate of caspase 3) were detected.Back to article page
