Organ transplantation is a vital intervention for end-stage organ failure; however, ischemia-reperfusion injury is a complication of transplantation, affecting the prognosis and survival of transplant recipients. As a complex ecosystem, recent research has highlighted the role of the intestinal microecology in transplantation, revealing its significant interplay with ischemia-reperfusion injury. This review explores the interaction between ischemia-reperfusion injury and intestinal microecology, with a special focus on how ischemia-reperfusion injury affects intestinal microecology and how these microecological changes contribute to complications after organ transplantation, such as infection and rejection. Based on a comprehensive analysis of current research advances, this study proposes potential strategies to improve transplant outcomes, offering guidance for future research and clinical practice.

The global shortage of suitable donor kidneys is the primary challenge in kidney transplantation, and it is exacerbated by ageing donors with increased numbers of health issues. Improving organ assessment, preservation and conditioning could enhance organ utilization and patient outcomes. Hypothermic machine perfusion (HMP) is associated with better results than static cold storage by reducing delayed graft function and improving short-term graft survival, especially in kidneys recovered from marginal-quality donors.

Static cold storage (SCS) on ice has remained the gold standard preservation method for heart transplantation, and prolonged cold ischemia outside the typical 4-6 hour window is associated with an increased risk of primary graft dysfunction - a consequence attributed to ischemic damage and reperfusion injury. This, unfortunately limits the travel radius for donor heart procurement, a key factor that contributes to the overall shortage of donor organs. Recent research and clinical data have illustrated the validity of other preservation systems in preserving cardiac allografts, and many of these devices have shown promise in potentially prolonging the tolerated ischemic time beyond the accepted standard.

20(R)-ginsenoside Rg3 can reduce the effects of oxidative stress and cell death in cerebral ischemia‒reperfusion injury (CIRI). Neuroinflammation is crucial post-CIRI, but how 20(R)-Rg3 affects ischemia‒reperfusion-induced neuroinflammation is unclear. To study 20(R)-Rg3's effects on neuroinflammation and neuronal preservation in stroke models and explore toll-like receptor 4/myeloid differentiation factor-88/nuclear factor kappa B (TLR4/MyD88/NF-κB) pathway mechanisms.
