Abstract

The NLR family pyrin domain‑containing 3 (NLRP3) inflammasome, which is composed of NLRP3, apoptosis‑associated speck‑like protein containing a CARD (ASC) and pro‑caspase‑1 protein complexes, is activated by the reactive oxygen species (ROS) that are associated with ischemia‑reperfusion (I/R) and are involved in brain damage. Pomelo peel oil (PPO) exhibits antioxidant activity. However, it is unclear whether PPO is able to attenuate NLRP3 inflammasome‑induced inflammation and pyroptosis. Healthy male Sprague‑Dawley rats were subjected to 7 min of cardiac arrest via trans‑esophageal electrical stimulation, followed by cardiopulmonary resuscitation (CPR). The rats were then treated with PPO prior to reperfusion for 24 h. Hematoxylin and eosin staining was used to evaluate brain tissue and cell damage. In the brain tissues, reactive oxygen species (ROS) were assayed, immunofluorescence was used to analyze the expression of NLRP3 and western blotting was performed to determine the expression levels of neuroenolase (NSE), NF‑κB, interleukin‑1β (IL‑1β), gasdermin D (GSDMD) and the NLRP3 inflammasome. Treatment of the rats with PPO significantly decreased the pathological damage of the brain tissue and reduced the expression of NSE, production of ROS and secretion of NF‑κB, NLRP3, IL‑1β and GSDMD. In conclusion, these results demonstrate the ability of PPO to protect the brain against I/R injury in rats after CPR by a mechanism involving inhibition of the inflammation and pyroptosis mediated by NLRP3 inflammasome activation.
