摘要:

中枢神经系统创伤包括创伤性脑损伤和创伤性脊髓损伤,通常伴随着组织炎症和免疫细胞的浸润,同时影响到神经干细胞的自我更新和分化。在没有外部干预的情况下,内源性神经干细胞很难促进中枢神经系统损伤恢复。最近,驻留/外周免疫细胞已被证明对神经干细胞有巨大的影响。因此,通过神经干细胞的免疫干预来促进中枢神经系统的创伤恢复是一种潜在的治疗方法。此综述讨论了免疫细胞对神经干细胞自我更新和分化的作用和可能的机制,以及基于免疫干预中枢神经系统损伤的预后。阐明这些问题将有助于神经干细胞在治疗中枢神经系统损伤中的成功应用。

Abstract: Traumatic injuries in the central nervous system, such as traumatic brain injury and spinal cord injury, are associated with tissue inflammation and the infiltration of immune cells, which simultaneously affect the self-renewal and differentiation of neural stem cells. However, the tissue repair process instigated by endogenous neural stem cells is incapable of restoring central nervous system injuries without external intervention. Recently, resident/peripheral immune cells have been demonstrated to exert significant effects on neural stem cells. Thus, the restoration of traumatic injuries in the central nervous system by the immune intervention in neural stem cells represents a potential therapeutic method. In this review, we discuss the roles and possible mechanisms of immune cells on the self-renewal and differentiation of neural stem cells along with the prognosis of central nervous system injuries based on immune intervention. Finally, we discuss remaining research challenges that need to be considered in the future. Further elucidation of these challenges will facilitate the successful application of neural stem cells in central nervous system injuries.
