细胞外小泡(EV)是几乎所有类型的细胞都能分泌的膜分隔颗粒。EVS介导中枢神经系统(CNS)的重要生理功能和病理生理过程。EV作为多种生物活性物质(如蛋白质、脂质和核酸)的载体,可以在外界刺激下进行修饰,成为神经创伤后的病理介质,如脊髓损伤(SCI)。在这里,我们讨论了中枢神经内源性EVS的作用以及与外周EVS的串扰与神经创伤的关系,尤其是SCI。然后,我们总结了在这些疾病的临床前动物模型中基于EV的治疗进展的现状。最后,我们讨论了新的生物工程策略,这些策略有望增强电动汽车的中枢神经系统特异性治疗能力。
Extracellular vesicles (EVs) are membrane-delimited particles secreted by nearly all cell types. EVs mediate critical physiological functions and pathophysiological processes in the central nervous system (CNS). As carriers of diverse bioactive cargo (e.g., proteins, lipids and nucleic acids) that can be modified in response to external stimuli, EVs have emerged as pathological mediators after neurotrauma, such as spinal cord injury (SCI). Here, we discuss the roles of endogenous EVs within the CNS as well as crosstalk with peripheral EVs in relation to neurotrauma, with particular focus on SCI. We then summarize the status of EV-based therapeutic advances in preclinical animal models for these conditions. Finally, we discuss new bioengineering strategies that are poised to enhance CNS-specific therapeutic capabilities of EVs.
