概括

这项研究引入了一种新的气体传递器-纳米龙系统,通过准"瘤-大脑轴"来同时治疗癌症和焦虑. 该系统提供硫化 (H2S) 来减少瘤和缓解类似焦虑的行为.

科学领域:

生物医学工程生物医学工程
神经科学是一个神经科学.
在瘤学瘤学.

背景情况:

在癌症患者中,焦虑是常见的,会对预后产生负面影响.
现有的癌症治疗方法往往缺乏减轻焦虑的效果,并可能使焦虑恶化.

研究的目的:

开发一种具有双重抗焦虑和抗瘤作用的气体传递器-纳米龙 (GND) 系统.
利用"瘤-大脑轴"策略来准癌症和焦虑.

主要方法:

合成的牛血清白蛋白 (BSA) 纳米颗粒 (FSG@AB) 共同嵌入Fe2+,S2−和葡萄糖氧化酶 (GOx).
利用酸性瘤微环境控制释放硫化 (H2S).
研究了H2S向前带带皮层 (ACC) 的运输及其对谷氨酸运输体1 (GLT-1) 和神经元活动的影响.

主要成果:

通过通过H2S和GOx.消耗瘤能量来源,GND系统证明了协同作用的抗瘤作用.
运送到ACC的H2S上调了GLT-1,减少了细胞外谷氨酸和神经元过活.
通过调节瘤-大脑轴,可以缓解类似焦虑的行为.

结论:

开发的GND系统有效地针对癌症的瘤和精神方面.
"瘤-大脑轴"战略为综合癌症和焦虑治疗提供了一个有希望的方法.
这种双重作用疗法有可能改善癌症护理患者的治疗结果.

关键词:

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists

Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...
