摘要
病理性疼痛是由传递痛觉刺激的神经回路活动异常引起的。除了稳态功能外,星形胶质细胞还作为三方突触的成员积极参与调节突触传递。突触周围星形胶质细胞过程(PAP)是星形胶质细胞发挥这些作用的关键结构,它不仅通过细胞粘附分子(CAM)在物理上支持突触的形成,还能调节化学信号的效率。越来越多的证据表明,脊髓星形胶质细胞通过位于 PAP 中的转运体调节谷氨酸和 GABA 等神经递质的功效,并通过各种神经胶质递质直接调节突触传递,从而参与病理性疼痛。虽然各种 CAMs 会导致病理性疼痛,但关于星形胶质细胞 CAMs 是否也具有这种作用,目前还没有足够的证据。因此,我们需要对星形胶质细胞如何诱导和维持病理性疼痛进行更深入的研究,尤其是在突触周围的 PAP 中,这将加深我们对病理性疼痛的理解和治疗。
Role of spinal astrocytes through the perisynaptic astrocytic process in pathological pain
Pathological pain is caused by abnormal activity in the neural circuit that transmits nociceptive stimuli. Beyond homeostatic functions, astrocytes actively participate in regulating synaptic transmission as members of tripartite synapses. The perisynaptic astrocytic process (PAP) is the key structure that allows astrocytes to play these roles and not only physically supports synapse formation through cell adhesion molecules (CAMs) but also regulates the efficiency of chemical signaling. Accumulating evidence has revealed that spinal astrocytes are involved in pathological pain by modulating the efficacy of neurotransmitters such as glutamate and GABA through transporters located in the PAP and by directly regulating synaptic transmission through various gliotransmitters. Although various CAMs contribute to pathological pain, insufficient evidence is available as to whether astrocytic CAMs also have this role. Therefore, more in-depth research is needed on how pathological pain is induced and maintained by astrocytes, especially in the PAP surrounding the synapse, and this will subsequently increase our understanding and treatment of pathological pain.
