Inhibition of PSM-mediated neutrophil lysis.

<p>Dose-dependent neutrophil lysis by synthetic PSMα1, PSMα2, PSMα3, and δ-toxin (400 nM to 100 µM), preincubated with or without 1% or 10% human serum. Neutrophil lysis was measured through LDH release. Data represent means ± SEM of three independent experiments.
