IBS应激反应现型与血液转录组概况以及微观结构和功能性大脑变化有关
具有较高应激反应能力 (SR) 的个体表现出交感神经系统 (SNS) 活动,炎症和大脑功能变化的增加,特别是在刺激性肠综合征 (IBS) 患者中. 这表明个性化IBS治疗的生物基础.
科学领域:
- 神经科学是一个神经科学.
- 遗传学 是一个遗传学.
- 精神病学是一个精神病学.
背景情况:
- 临床观察显示,压力反应能力 (SR) 的个体变异性显著.
- 这些SR差异的潜在生物机制和治疗相关性在很大程度上仍未被探索.
- 了解这些差异对于像刺激性肠综合征 (IBS) 这样的疾病至关重要.
研究的目的:
- 为了确定提高SR的生物基础.
- 调查心理测量SR表型,血液转录组学 (交感神经系统 (SNS) 激活) 和IBS患者和健康对照 (HCs) 中的大脑成像之间的关系.
主要方法:
- 这是一项涉及291名参与者 (IBS和HC) 的横截面研究.
- 利用转录学分析,多式脑成像和心理社会评估.
- 员工无监督集群,以定义高SR和低SR子组进行比较分析.
主要成果:
- 较高SR组显示循环AMP响应元素结合蛋白 (CREB) 基因表达升高,表明SNS活力和炎症.
- 大脑成像揭示了高SR组的神经塑性变化,包括高调节的兴奋系统和中央自主网络内的功能连接的改变.
- 在肠外症状中,SR影响了基于性别的差异.
结论:
- 这些发现支持了一个模型,其中持续的SNS活动有助于提高自主反应能力,低级免疫激活,并可能导致IBS.
- 这些对SR的生物学见解可能为IBS管理中个性化治疗策略铺平道路.
