Behavioral testing is an essential tool for evaluating cognitive function and dysfunction in preclinical research models. This is of special importance in the study of neurological disorders such as Alzheimer's disease. However, the reproducibility of classic behavioral assays is frequently compromised by interstudy variation, leading to ambiguous conclusions about the behavioral markers characterizing the disease. Here, we identify age- and genotype-driven differences between 3xTg-AD and non-transgenic control mice using a low-cost, highly customizable behavioral assay that requires little human intervention. Through behavioral phenotyping combining both supervised and unsupervised behavioral classification methods, we are able to validate the preventative effects of the immunosuppressant cyclosporine A in a rodent model of Alzheimer's disease, as well as the partially ameliorating effects of candidate drugs nebivolol and cabozantinib.
行为测试是评估临床前研究模型中认知功能和功能障碍的重要工具。这在诸如阿尔茨海默病等神经疾病的研究中尤为重要。然而,经典行为试验的可重复性常常因研究间差异而受到影响,导致关于表征该疾病的行为标志物的结论模棱两可。在此,我们使用一种低成本、高度可定制且几乎无需人工干预的行为试验,确定了3xTg-AD小鼠与非转基因对照小鼠之间年龄和基因型驱动的差异。通过结合监督式和非监督式行为分类方法的行为表型分析,我们能够验证免疫抑制剂环孢素A在阿尔茨海默病啮齿动物模型中的预防作用,以及候选药物奈必洛尔和卡博替尼的部分改善作用。
