942-氧化磷脂沉积驱动慢性神经退行性变研究

from 聊聊Sci

这项研究揭示了氧化磷脂质(OxPCs)在进行性多发性硬化症(P-MS)慢性神经变性中的核心驱动作用。研究人员通过在小鼠体内沉积OxPCs,成功模拟了人类患者中常见的慢性活动性病变(CALs),并发现其病理特征与临床表现高度一致。实验表明,炎症因子IL-1β与氧化磷脂质之间存在正反馈循环,不断加剧神经炎症与轴突损伤。此外,高龄会通过改变小胶质细胞的功能显著恶化病变程度,而小胶质细胞的缺失反而会导致更严重的神经退行性病变。该成果强调了中和OxPCs或阻断IL-1β信号通路可能是治疗进行性多发性硬化症的潜在有效策略。References:Yu R, Lozinski B M, Seifert A, et al.
