肝脏缺血再灌注损伤(IRI)是包括器官移植在内的肝脏手术后器官功能障碍和衰竭的主要原因。肝脏IRI的机制复杂,涉及众多信号,但细胞代谢紊乱、氧化应激和炎症被认为是肝脏IRI的主要促成因素。此外,炎症信号的激活通过募集巨噬细胞、树突状细胞和中性粒细胞,以及激活自然杀伤细胞、自然杀伤T细胞和细胞毒性T细胞,加剧了肝脏IRI。技术的进步使我们能够了解特定免疫细胞在肝脏IRI过程中的作用。因此,已经提出了预防或治疗肝脏IRI的治疗策略,但目前还没有确定有效的疗法。这篇综述总结了免疫细胞功能的最新进展,并讨论了在肝脏IRI中的治疗潜力。更好地理解这一复杂且高度动态的过程可能有助于开发创新的治疗方法并优化患者的治疗效果。
Liver ischemia-reperfusion injury (IRI) is the main cause of organ dysfunction and failure after liver surgeries including organ transplantation. The mechanism of liver IRI is complex and numerous signals are involved but cellular metabolic disturbances, oxidative stress, and inflammation are considered the major contributors to liver IRI. In addition, the activation of inflammatory signals exacerbates liver IRI by recruiting macrophages, dendritic cells, and neutrophils, and activating NK cells, NKT cells, and cytotoxic T cells. Technological advances enable us to understand the role of specific immune cells during liver IRI. Accordingly, therapeutic strategies to prevent or treat liver IRI have been proposed but no definitive and effective therapies exist yet. This review summarizes the current update on the immune cell functions and discusses therapeutic potentials in liver IRI. A better understanding of this complex and highly dynamic process may allow for the development of innovative therapeutic approaches and optimize patient outcomes.
