摘要:

卫星胶质细胞是包绕在初级感觉神经元胞体周围的一类独特的胶质细胞。越来越多的证据表明在炎症和神经损伤的条件下,卫星胶质细胞可大量激活,引发一系列功能变化。这提示卫星胶质细胞与慢性疼痛的发生过程密切相关。此次综述首先概况了卫星胶质细胞的形态结构、分子标记物和生理功能,然后阐明卫星胶质细胞在慢性疼痛中扮演的多重关键角色,包括缝隙连接半通道连接蛋白43和细胞质膜通道Pannexin 1、Kir4.1通道、ATP及其P2嘌呤能受体、肿瘤坏死因子及其受体、谷氨酸及其受体、内皮素及其受体、缓激肽及其受体。最后提出未来还应关注卫星胶质细胞的特异性分选、生理和病理状态下的基因组差异等方面的探索。该综述为阐明慢性疼痛的外周调节机制提供了重要视角,并有助于制定新的慢性疼痛治疗方案。

Abstract: Satellite glial cells are unique glial cells that surround the cell body of primary sensory neurons. An increasing body of evidence suggests that in the presence of inflammation and nerve damage, a significant number of satellite glial cells become activated, thus triggering a series of functional changes. This suggests that satellite glial cells are closely related to the occurrence of chronic pain. In this review, we first summarize the morphological structure, molecular markers, and physiological functions of satellite glial cells. Then, we clarify the multiple key roles of satellite glial cells in chronic pain, including gap junction hemichannel Cx43, membrane channel Pannexin1, K channel subunit 4.1, ATP, purinergic P2 receptors, and a series of additional factors and their receptors, including tumor necrosis factor, glutamate, endothelin, and bradykinin. Finally, we propose that future research should focus on the specific sorting of satellite glial cells, and identify genomic differences between physiological and pathological conditions. This review provides an important perspective for clarifying mechanisms underlying the peripheral regulation of chronic pain and will facilitate the formulation of new treatment plans for chronic pain.
