细胞信号传输细胞信号传输

背景情况:

阿尔法-同核素 (Syn) 是一种前突触神经元蛋白质,在中枢神经系统之外的作用尚不清楚.
唾液腺中的肌皮细胞在唾液分泌和组成中起着至关重要的作用.

研究的目的:

为了研究大鼠唾液腺中α-synuclein (Syn) 的表达和定位.
探索Syn与唾液腺细胞的潜在相互作用及其在神经元调节中的作用.

主要方法:

免疫组织化学被用来检测下下,下语言和语言腺体的Syn表达.
同焦激光扫描显微镜检查了与光滑肌肉动蛋白 (SMA) 和水素-5 (AQP5) 表达细胞相关的同免疫性神经纤维.
在各种神经元群体中,分析了Syn与氨酸氧酶 (TH) 和胆酸转移酶 (ChAT) 的同时表达.

主要成果:

丰富的syn-immunoreactive神经纤维在下下腺的管道周围和在下舌腺和舌腺的acini观察到.

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
