Ischemia/reperfusion (I/R) injury is marked by the restriction and subsequent restoration of blood supply to an organ. This process can exacerbate the initial tissue damage, leading to further disorders, disability, and even death. Extracellular vesicles (EVs) are crucial in cell communication by releasing cargo that regulates the physiological state of recipient cells. The development of EVs presents a novel avenue for delivering therapeutic agents in I/R therapy. The therapeutic potential of EVs derived from stem cells, endothelial cells, and plasma in I/R injury has been actively investigated. Therefore, this review aims to provide an overview of the pathological process of I/R injury and the biophysical properties of EVs. We noted that EVs serve as nontoxic, flexible, and multifunctional carriers for delivering therapeutic agents capable of intervening in I/R injury progression. The therapeutic efficacy of EVs can be enhanced through various engineering strategies. Improving the tropism of EVs surface modification and modulating their contents via preconditioning are widely investigated in preclinical studies. Finally, we summarize the challenges in the production and delivery of EV-based therapy in I/R injury and discuss how it can advance. This review will encourage further exploration in developing efficient EV-based delivery systems for I/R treatment.

Bufalin, which is isolated from toad venom, exerts positive effects on hearts under pathological circumstance. We aimed to investigate the effects and mechanisms of bufalin on myocardial I/R injury. In vivo, bufalin ameliorated myocardial I/R injury, which characteristics with better ejection function, decreased infarct size and less apoptosis.

Despite improvements in interventional techniques leading to faster myocardial reperfusion postmyocardial infarction, there has been a significant rise in the occurrence of myocardial ischaemia/reperfusion injury (MI/RI). A deeper understanding of the underlying mechanisms of MI/RI could offer a crucial approach to reducing myocardial damage and enhancing patient outcomes. This study examined the myocardial protective properties of puerarin (PUE) in the context of MI/RI using hypoxia/reoxygenation (H/R) or ischaemia/reperfusion (I/R) injury models were employed in H9c2 cells and C57BL/6 mice.

Background: We sought to define whether and how hepatic ischemia/reperfusion (I/R) as manifested by perioperative aspartate aminotransferase (AST) and alanine aminotransaminase (ALT) levels impact long-term outcomes after curative-intent resection of hepatocellular carcinoma (HCC).
Patients And Methods: Intrasplenic injection of HCC cells was used to establish a murine model of HCC recurrence with versus without I/R injury. Patients who underwent curative resection for HCC were identified from a multi-institutional derivative cohort (DC) and separate external validation (VC) cohort.

Nuclear factor erythroid 2-related factor 2 (NRF2) is a redox-sensitive transcriptional factor that enables cells to resist oxidant responses, ferroptosis and inflammation. Here, we set out to probe the effects of NRF2 on cardiomyocyte injury under acute myocardial infarction (AMI) condition and its potential mechanism. Human cardiomyocytes were exposed to hypoxia/reoxygenation (H/R) to induce cell injury.

Introduction: Ischemia followed by reperfusion in organ transplantations can lead to ischemia-reperfusion (I-R) injury, which is associated with oxidative stress and inflammatory responses. Alpha-pinene is an organic terpene with well-known antioxidant, anti-inflammatory, and anti-apoptotic properties. This study examines the preventive effects of alpha-pinene against renal I-R-induced kidney dysfunction, oxidative and inflammatory status, apoptosis, and histopathology changes.
