摘要:

神经元泛凋亡是一种新近报道的细胞死亡模式,其特征为凋亡、凋亡样凋亡和坏死样凋亡,在缺血性脑损伤后的病理生理过程中发挥重要作用;然而,其确切的潜在机制尚未完全阐明。实验旨在阐明缺血性脑损伤后神经元泛凋亡中S100钙结合蛋白A10(S100A10)的功能,以及Sonic Hedgehog(Shh)和S100A10对神经元泛凋亡的影响及其机制。结果显示,S100A10在缺血性脑卒中的细胞和动物模型中均显著上调。敲低S100A10进一步增强了缺血性脑卒中后神经元PANoptosis及相关蛋白的水平。Shh治疗导致S100A10表达上调,并削弱了S100A10敲低对神经元泛凋亡的促进作用。S100A10与Shh的结合为开发治疗缺血性脑卒中的有效疗法提供了有前景的途径,具有显著的未来临床应用潜力。

Abstract: Acute ischemic stroke is a highly prevalent and disabling disease with poor prognosis. Neuronal death is a major feature after a stroke. PANoptosis is a newly reported pattern of cell death, characterized by pyroptosis, apoptosis, and necroptosis, that plays an important role in the pathophysiological process after ischemic brain injury. However, its precise underlying mechanisms have not yet been fully elucidated. This study aimed to clarify the function of S100 calcium-binding protein A10 in neuronal PANoptosis after ischemic brain damage and to investigate the impact and mechanism of sonic hedgehog and S100 calcium-binding protein A10 on PANoptosis. The results showed that S100 calcium-binding protein A10 was significantly upregulated in both cellular and animal models of ischemic stroke. Knockdown of S100 calcium-binding protein A10 exacerbated PANoptosis and the levels of PANoptosis-related proteins following cerebral ischemia damage. Sonic hedgehog treatment increased S100 calcium-binding protein A10 and inhibited the increase in PANoptosis induced by S100 calcium-binding protein A10 knockdown. The findings suggest that sonic hedgehog intervention mitigated neuronal PANoptosis ensuing from ischemic stroke. The combination of S100 calcium-binding protein A10 and sonic hedgehog demonstrated promise for developing an effective therapy against cerebral ischemic stroke, which would have significant potential for future clinical applications.
