概括
在7%的人类胰腺和几种动物中发现了帕西尼体. 虽然它们的尺寸和形状不同,但它们的核心结构和免疫组织化学特征相似,这表明它们的机理受体功能得到保护.
科学领域:
- 神经科学
- 组织学
- 比较解剖学
背景情况:
- 帕西尼体细胞 (PCs) 是专门的机械受体, 对于感知压力和振动至关重要.
- 尽管在其他组织和猫类胰腺中有记录的发生,但它们在正常胰腺中的存在一直存在争议.
研究的目的:
- 研究正常人胰腺中帕西尼细胞的分布和特征.
- 将这些发现与几种动物的胰腺中PC的存在和形态进行比较.
主要方法:
- 在74个人类尸体胰腺样本上进行了组织学和免疫组织化学分析.
- 还检查了来自Cynictis penicillata,Saguinus mystax,Felis domesticus和Suncus murinus的胰腺组织.
主要成果:
- 在7%的人类胰腺和Cynictis penicillata,Saguinus mystax和Felis domesticus中发现了帕西尼体,但没有Suncus murinus.
- 与动物发现的圆形PC相比,人类的胰腺PC较大,但数量较少,形状不规则.
- 在人类和动物胰腺PC中,免疫组织化学检测显示蛋白质基因产物9. 5和维门丁的表达一致.
结论:
- 这项研究证实了Pacinian体在健康人胰腺和几种动物中的存在.
- 人类和动物胰腺PC在数量,大小和形态上存在显著差异,但它们的基本结构和免疫组织化学特征保持不变.
- 帕西尼细胞在人类胰腺中的生理作用仍然是需要进一步研究的领域.

The pancreas, a vital organ within the abdominal cavity, plays dual roles in the digestive and endocrine systems, collaborating with exocrine and endocrine cells to maintain optimal digestion and blood sugar levels.
Exocrine function is carried out by acinar cells, organized into clusters known as acini. These cells contribute to digestion by releasing substantial quantities of enzyme-rich, alkaline digestive juices.
Concurrently, the dispersed clusters of endocrine cells throughout the...

The pancreas, an essential organ in the human body, is a pinkish-gray elongated structure located posterior to the stomach. It extends laterally from the duodenum towards the spleen and is firmly bound to the posterior wall of the abdominal cavity. The organ's surface has a lumpy, lobular texture that gives it a unique appearance.
The broad head of the pancreas lies within the loop formed by the duodenum, while its slender body reaches towards the spleen. The tail of the pancreas is short...
