RESUMEN
Pyroptosis is a form of new programmed cell death which is dependent on Caspase-1 in recent years.When it' s stimulated by various dangerous signals from hepatic ischemia-reperfusion injury,the intracellular pattern recognition receptors are assembled into inflammasomes and Caspase-1 which was transformed into active form.Activated Caspase-1 promotes the maturation and secretion of pro-inflammatory cytokines IL-1β and IL-18,initiates the innate immunity rapidly and then induces severe inflammatory reaction.In addition,Caspase-1 can also cleave Gasdermin D and release its N-terminal domain triggering pyroptosis.Many studies showed that pyroptosis play a crucial role in hepatic ischemia-reperfusion injury.In this review,we discussed the activation mechanism and research progress of pyroptosis in hepatic ischemia-reperfusion injury.
