Inflammation is the first line of defense against injury and infection and works both by controlling the ongoing pathological processes and by promoting neuroprotection and regeneration. When the inflammatory response is hyper activated, it plays a pivotal role in the pathophysiology of many neurological diseases, as it can also be a source of additional injury to host cells. Since neurons lack the ability to divide and recover poorly from injury, they are extremely vulnerable to auto destructive immune and inflammatory processes, and this side effect is fundamental to the outcome of neurological diseases. Inappropriate immune responses are responsible for diseases such as Multiple Sclerosis (MS), Alzheimer's disease (AD) or Parkinson's disease (PD) and for the increased disability after brain trauma or stroke. However, in certain circumstances immune responses in the brain might have a neuroprotective effect, possibly mediated by the release of trophic factors from inflammatory and/or glial cells. The nerve growth factor (NGF) was the first neurotrophin discovered for its stimulatory effect on differentiation, survival, and growth of neurons in peripheral and central nervous system. This factor can protect axons and myelin from inflammatory damage and also can modulate the immune system, reducing the enhanced excitotoxicity during acute inflammatory activation. Therefore, because its neuroprotective activity and immunomodulatory effects, NGF may represent a new therapeutic approach for the treatment of numerous brain disorders.

靶向NGF途径,用于开发多发性硬化症和其他神经系统疾病的神经保护疗法。

炎症是抵抗伤害和感染的第一道防线,它通过控制正在进行的病理过程并促进神经保护和再生而起作用。当炎症反应过度激活时,它在许多神经系统疾病的病理生理中起着关键作用,因为它也可能是宿主细胞受到额外伤害的来源。由于神经元缺乏从损伤中分裂和恢复的能力,因此它们极易受到自身破坏性免疫和炎症过程的影响,而这种副作用是神经系统疾病预后的基础。不适当的免疫反应会导致多种疾病,例如多发性硬化症(MS),阿尔茨海默氏病(AD)或帕金森氏病(PD),以及导致脑外伤或中风后残疾增加。然而,在某些情况下,大脑中的免疫反应可能具有神经保护作用,可能是由炎性和/或神经胶质细胞释放营养因子介导的。神经生长因子(NGF)是第一个发现的神经营养蛋白,具有刺激周围和中枢神经系统神经元分化,存活和生长的作用。该因子可以保护轴突和髓磷脂免受炎性损害,还可以调节免疫系统,减少急性炎症激活过程中增强的兴奋性毒性。因此,由于其神经保护活性和免疫调节作用,NGF可能代表了一种治疗多种脑部疾病的新治疗方法。可能是由炎性和/或神经胶质细胞释放营养因子介导的。神经生长因子(NGF)是第一个发现的神经营养蛋白,具有刺激周围和中枢神经系统神经元分化,存活和生长的作用。该因子可以保护轴突和髓磷脂免受炎性损害,还可以调节免疫系统,减少急性炎症激活过程中增强的兴奋性毒性。因此,由于其神经保护活性和免疫调节作用,NGF可能代表了一种治疗多种脑部疾病的新治疗方法。可能是由炎性和/或神经胶质细胞释放营养因子介导的。神经生长因子(NGF)是第一个发现的神经营养蛋白,具有刺激周围和中枢神经系统神经元分化,存活和生长的作用。该因子可以保护轴突和髓磷脂免受炎性损害,还可以调节免疫系统,减少急性炎症激活过程中增强的兴奋性毒性。因此,由于其神经保护活性和免疫调节作用,NGF可能代表了一种治疗多种脑部疾病的新治疗方法。该因子可以保护轴突和髓磷脂免受炎性损害,还可以调节免疫系统,减少急性炎症激活过程中增强的兴奋性毒性。因此,由于其神经保护活性和免疫调节作用,NGF可能代表了一种治疗多种脑部疾病的新治疗方法。该因子可以保护轴突和髓磷脂免受炎性损害,还可以调节免疫系统,减少急性炎症激活过程中增强的兴奋性毒性。因此,由于其神经保护活性和免疫调节作用,NGF可能代表了一种治疗多种脑部疾病的新治疗方法。
