摘要:

近年来淋巴系统被发现可在大脑中作为一种流体交换和运输系统。越来越多的证据表明,淋巴功能不仅在中枢神经系统疾病中受损,也在全身性疾病中受损,且全身性疾病会引发中枢神经系统的炎症反应,偶尔会导致中枢神经系统持续炎症和功能紊乱。此次综述总结了淋巴功能障碍与中枢神经系统炎症之间的关系;还讨论了一种假设,即最初与外周炎症相关的疾病会压垮肾上腺系统,从而引发中枢神经系统功能障碍、慢性神经炎症和神经变性。

Abstract: The glymphatic system is a relatively recently identified fluid exchange and transport system in the brain. Accumulating evidence indicates that glymphatic function is impaired not only in central nervous system disorders but also in systemic diseases. Systemic diseases can trigger the inflammatory responses in the central nervous system, occasionally leading to sustained inflammation and functional disturbance of the central nervous system. This review summarizes the current knowledge on the association between glymphatic dysfunction and central nervous system inflammation. In addition, we discuss the hypothesis that disease conditions initially associated with peripheral inflammation overwhelm the performance of the glymphatic system, thereby triggering central nervous system dysfunction, chronic neuroinflammation, and neurodegeneration. Future research investigating the role of the glymphatic system in neuroinflammation may offer innovative therapeutic approaches for central nervous system disorders.
