Core Tip |
Activated macrophages release large amounts of interleukin-1β (IL-1β) and macrophages deficient in caspase-1 expression have undetectable IL-1β secretion. This suggests that IL-1β release and caspase-1 activation are closely related events. We found that human α-defensin 5 (HD-5) inhibited the release of IL-1β, but not the processing of pro-IL-1β to IL-1β in lipopolysaccharide-activated monocytes stimulated with Adenosine triphosphate or nigericin. Different from IL-1β processing and release, the activation and release of caspase-1 from stimulated monocytes was not blocked by HD-5. These data suggest that caspase-1 activation/processing of pro-IL-1β by caspase-1 and the release of mature IL-1β from human monocytes are distinct and separable events. |
