主要成果:
- 在人类SCG中确定了三个不同的神经元群 (两个noradrenergic,一个胆固醇) 和九个非神经元群.
- 在糖尿病SCG中观察到肌化施万细胞的丧失和胆固醇神经元身份的转变.
- 在糖尿病SCG中发现了血管扩张神经的减少表达 (例如,VIP,CALCA) 和神经营养信号的改变 (NGF/TRKA,BDNF/TRKB).
- 发现了SCG (例如,SCN3A,NPY) 与背部根 (DRG) (例如,SCN10A,GPX1) 的独特基因特征.
结论:
- 提供了人类SCG的全面转录基因地图,详细说明了它的细胞组成.

Collateral Ganglia
Sympathetic preganglionic axons reach the collateral ganglia along the route of splanchnic nerves. These nerves bypass the sympathetic trunk and communicate with sympathetic postganglionic neurons housed in the prevertebral ganglia. These ganglia supply the organs of the abdominopelvic cavity.
The greater splanchnic nerve, formed by the...

Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...
