摘要
背景:阿尔茨海默氏病(AD)挑战了单靶标治疗策略,增加了联合疗法可能提供更有效治疗策略的可能性。 目的:有充分的证据证明瘦素(L)(神经保护激素)和吡格列酮(P)(抗炎药)在AD中的单一疗法有效。先前我们已经表明,在病理发生时,在APP / PS1小鼠中联合治疗L + P相对于对照小鼠,显着改善了记忆力并降低了大脑Aβ水平。在这项新研究中,我们试图在一个新的APP / PS1小鼠队列中复制我们以前的发现,以进一步证实L + P的联合治疗是否优于单独的每种治疗。 方法:我们使用硫代黄素-S染色,MOAβ免疫标记和酶联免疫吸附测定(ELISA),重新评估了L + P联合治疗对APP / PS1小鼠的作用,以检查相对于Aβ水平和病理学的影响分别接受L或P的动物。 结果:我们证明,L和P的组合可显着增强APP / PS1小鼠海马中L或P的抗Aβ效应。 结论:我们的研究结果表明,将L和P联合使用可显着增强L / P在APP / PS1小鼠海马中的抗Aβ效应,可能是AD治疗的潜在新有效策略。
