概括

前带皮质中的受体氨酸激酶类孤儿受体2 (Ror2) 通过改变星细胞平衡和肠道微生物群,导致慢性疼痛. 在星球细胞中抑制Ror2可以缓解疼痛行为,并恢复肠道微生物群的平衡.

科学领域:

神经科学是一个神经科学.
疼痛研究疼痛研究
微生物组研究微生物组研究

背景情况:

受体氨酸激酶类孤儿受体2 (Ror2) 对于疼痛信号传递至关重要.
之前的研究表明,脊髓星球细胞衍生的Ror2与慢性胸切除术后疼痛 (CPTP) 有关.
这项研究调查了前带皮层 (ACC) Ror2和肠道微生物群在CPTP中的作用.

研究的目的:

探索ACC Ror2在CPTP中的参与.
检查肠道微生物群对CPTP的影响.
确定在CPTP中准天体细胞Ror2的治疗潜力.

主要方法:

建立了CPTP的老鼠模型.
评估了疼痛行为 (机械性过敏症,寒冷的整体运动).
在ACC星球细胞中利用了AAV介导的Ror2敲除,并分析了基因/蛋白质表达,星球细胞两极化和肠道短链脂肪酸 (SCFA).

主要成果:

在CPTP大鼠中,ACC中的升高的天体细胞Ror2与A1天体细胞两极化相关,CCL2/CXCL1增加,肠道SCFA减少.
Knockdown 的天体细胞Ror2显著减少了疼痛行为.
抑制Ror2恢复了星细胞平衡,降低了化学激素的表达,增加了SCFA水平.

结论:

CPTP的发展涉及Ror2介导的ACC天体细胞平衡和肠道微生物群的破坏.
向天体细胞Ror2为CPTP提供了潜在的治疗策略,通过恢复天体细胞平衡和减轻病原性影响.

关键词:

在CCL2中,我们可以使用CCL2.在CXCL1中,CXCL1是最重要的.这就是Ror2的作用.前带状皮层前带状皮层星球细胞是星球细胞.经胸切除术后的慢性疼痛.短链脂肪酸短链脂肪酸

Gut-Brain Axis

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such...

Intestinal Obstruction II: Pathophysiology

Intestinal Obstruction II: Pathophysiology

Intestinal obstruction triggers a series of physiological responses, starting with gas and fluid accumulation in the bowel segment proximal to the obstruction, leading to distension. This distended intestine compresses the diaphragm, hindering lung expansion and potentially leading to reduced respiratory effort, atelectasis, and pneumonia.To overcome the blockage, the gut intensifies contractions, causing colicky abdominal pain, nausea, and vomiting, which reduces fluid and food intake and...
