- 精神病学是一个精神病学.
- 动物模型 动物模型
背景情况:
- 双极性障碍涉及极端的情绪波动,其中涉及多巴胺系统失衡.
- 现有的动物模型往往缺乏模拟躁狂和抑郁情节之间的切换的能力.
研究的目的:
- 开发一种新的,有效的动物模型来治疗双相情感障碍.
- 研究多巴胺D1受体表达在情绪状态转换中的作用.
主要方法:
- 在大鼠中介前额叶皮层中,对多巴胺D1受体表达的四环素诱导性lentiviral构造物的立体注射.

02:43Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
