阿尔茨海默病的特征在于进行性认知障碍和神经递质功能障碍。先前针对肾上腺素能A1通路的研究表明,这在阿尔茨海默病的认知障碍中起作用。先前的研究报告称,使用A1拮抗剂进行急性治疗似乎可以改善啮齿动物记忆和行为障碍模型的行为缺陷。在这项研究中,我们解决了是否长期给予8-环戊基-1,3-二丙基黄嘌呤,一种有效的和选择性的腺苷A1拮抗剂,可以扭转老年APPswe/PS1 dE 9小鼠的记忆缺陷。长期治疗没有改善APPswe/PS1 dE 9小鼠模型的记忆,并导致探索行为减少,表明焦虑减少,非转基因小鼠的长期记忆恶化。这些结果对于理解A1受体调节作为阿尔茨海默病治疗靶点的机制具有重要意义。
Alzheimer's disease is characterized by progressive cognitive disturbances and neurotransmitter dysfunction. Previous studies targeting the adrenergic A1 pathway suggest that this plays a role in cognitive impairment in Alzheimer's disease. Previous studies have reported that acute treatment with A1 antagonists appears to improve behavioral deficits in rodent models of memory and behavioral impairment. In this study, we addressed whether the chronic administration of 8-cyclopentyl-1,3-dipropylxanthine, a potent and selective adenosine A1 antagonist, could reverse the memory deficits found in aged APPswe/PS1dE9 mice. Chronic treatment did not improve memory in the APPswe/PS1dE9 mouse model and resulted in reduced exploratory behavior, suggestive of reduced anxiety, and a worsening of long-term memory in nontransgenic mice. These results have important implications for understanding the mechanisms of A1 receptor modulation as a target in Alzheimer's disease therapy.
