WebMar 23, 2024 · Here, we show that gasdermin D (GSDMD), an executor of pyroptosis, is required for the rapid induction of IL-1α maturation by non-particulate inflammasome activators. Ablation of GSDMD abrogates the maturation of IL-1α, but not of IL-1β. Inflammasome-induced maturation of IL-1α relies on extracellular Ca2+and calpains.
