概括

在老鼠中,新生儿过度营养引起的肥胖症降低了脑干中血清素转运体 (SERT) 表达. 这导致了更少的节奏和增加的食物摄入量,突出了肥胖,机制和SERT之间的联系.

科学领域:

神经科学是一个神经科学.
肥胖问题研究研究
动物模型动物模型

背景情况:

肥胖与功能受损有关,其特点是咬伤尺寸更大,速度更快.
中脑三角核 (MTN) 对于通过感官输入协调和吞至关重要.
中毒素转运体 (SERT) 影响神经传递,并与肥胖的参数有关.

研究的目的:

研究饮食诱导的肥胖对体质生长,功能和MTN中SERT表达的影响.
建立使用 litter size 减小的肥胖的老鼠模型,研究其对和神经通路的影响.

主要方法:

维斯塔鼠被分为对照组 (9只/母) 和小 litter (3只/母) 组.
评估的体重,脂肪组织质量,时的食物摄入量和部运动.
在中大脑三角核中进行了血清载体免疫组织化学.

主要成果:

过度养的老鼠体重增加,食物消耗增加,脂肪组织积累增加.
分析显示,过度养的老鼠的次序较长,率较低.
在过度养大鼠的MTN中观察到减少SERT免疫活性,较大的神经元直径和较低的神经元密度.

结论:

新生儿过度营养引起的肥胖会降低MTN中的SERT表达.
减少SERT表达与节奏较低的和增加的食物摄入量相关.
建立了肥胖,功能和中央血清激素通路之间的重要联系.

关键词:

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...
