来源:Yan, Z., et al. 评估小药散对慢性压力小鼠的抗抑郁效果。J. Vis. Exp. (2019).
该视频演示了建立慢性压力诱发的抑郁症小鼠模型和评估抑郁行为的过程。各种压力源的慢性应用会触发皮质酮的释放,导致神经元过度兴奋并最终导致神经元死亡,从而导致小鼠出现类似抑郁的症状。
所有涉及动物模型的程序都经过当地机构动物护理委员会和 JoVE 兽医审查委员会的审查。
1.为实验程序
准备小鼠注意:在实验程序中,选择了 12 周龄的健康雄性 C57BL/6J 小鼠,每只小鼠体重在 18 至 22 g 之间。
2. 小鼠抑郁的诱导
注意:为了诱导抑郁,模型组和两个治疗组的小鼠接受了慢性不可预测的轻度应激 (CUMS) 21 天。可以根据实际情况改变计划,但应遵循不能连续使用同一压力源的原则。
