基因表达模式和网络属性的比较.
使用人类MDD患者数据作为参考标准.

主要成果:

慢性压力广泛改变了基因和功能,特别是涉及线粒体功能障碍.
肠道失生症特别影响了囊泡运输和自途径,具有更窄的基因范围.
网络分析表明,等级基因共同表达受到肠道失调的独特影响,与炎症和突触功能障碍有关.

结论:

肠道功能障碍和慢性压力会诱导与MDD相关的明显的大脑转录变化.
肠道功能障碍与自性失调,微质介导炎症和突触功能障碍有关.
这些发现突显了抑郁症的多样性,并为未来的研究提供了资源.

Depression: Overview

Depression: Overview

Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
