摘要: Neural Regen Res:表皮生长因子受体抑制剂:抗癌药物在阿尔茨海默病治疗中的潜在重新定位
    使用原代培养的星形胶质细胞和缺乏氧气和葡萄糖的 CTX-TNA2 细胞检查表皮生长因子受体抑制剂阿法替尼的抗炎作用的研究证明了氧糖剥夺介导了表皮生长因子受体磷酸化并刺激了下游信号通路,如 Akt 和细胞外调节蛋白激酶。阿法替尼修正了细胞增殖生物标志物胶质纤维酸性蛋白,增殖细胞核抗原水平和缺氧介导的迁移能力。阿法替尼抑制环加氧酶-II、一氧化氮、诱导型一氧化氮合酶、caspase-1 和白细胞介素-1β 水平。最近的一项研究表明,施用表皮生长因子受体抑制剂依鲁替尼可改善转基因小鼠的行为和病理变化。神经保护作用是通过抑制淀粉样β-蛋白、p-tau、细胞周期蛋白依赖性激酶 5 和促炎细胞因子介导的。如 6 个月大的转基因阿尔茨海默病小鼠的海马和大脑皮层中淀粉样β-蛋白负荷降低所证明的,依鲁替尼抑制了阿尔茨海默病初级和中期β-淀粉样蛋白的发育。
来自埃及药品管理局药理学系的Mahmoud M. Khattab团队讨论了表皮生长因子受体活化引起的不同病理效应。表皮生长因子受体抑制减轻损伤后星形胶质细胞增生,增强自噬,改善淀粉样β-蛋白毒性,神经炎症和再生轴突降解。但是,许多方面似乎都没有得到充分研究,例如表皮生长因子受体和 NOX-1 介导的氧化应激之间的联系,以及通过抑制谷氨酸介导的兴奋性毒性而抑制表皮生长因子受体的神经保护作用。总之,表皮生长因子受体信号通路的变化与阿尔茨海默病的发生和进展有关,证实抑制表皮生长因子受体表达或信号传导可能对了解神经变性有神经保护价值。建议应该开展临床试验以了解表皮生长因子受体抑制剂作为阿尔茨海默病缓解疗法的潜力,并阐明通过表皮生长因子受体抑制调节下游信号通路如何发挥神经保护作用。

Abstract: Numerous molecular mechanisms are being examined in an attempt to discover disease-modifying drugs to slow down the underlying neurodegeneration in Alzheimer’s disease. Recent studies have shown the beneficial effects of epidermal growth factor receptor inhibitors on the enhancement of behavioral and pathological sequelae in Alzheimer’s disease. Despite the promising effects of epidermal growth factor receptor inhibitors in Alzheimer’s disease, there is no irrefutable neuroprotective evidence in well-established animal models using epidermal growth factor receptor inhibitors due to many un-explored downstream signaling pathways. This caused controversy about the potential involvement of epidermal growth factor receptor inhibitors in any prospective clinical trial. In this review, the mystery beyond the under-investigation of epidermal growth factor receptor in Alzheimer’s disease will be discussed. Furthermore, their molecular mechanisms in neurodegeneration will be explained. Also, we will shed light on SARS-COVID-19 induced neurological manifestations mediated by epidermal growth factor modulation. Finally, we will discuss future perspectives and under-examined epidermal growth factor receptor downstream signaling pathways that warrant more exploration. We conclude that epidermal growth factor receptor inhibitors are novel effective therapeutic approaches that require further research in attempts to be repositioned in the delay of Alzheimer’s disease progression.
