Vasomotor ganglionic transmission: the preganglionic peptide and the second gear

血压取决于从中枢神经系统传递到血管的神经信号。在这条通路的中间是一个中继站——交感神经节细胞。通过这个中继站的传输最近被证明不仅有一个固定的组件，而且还有一个可变的组件-“第二齿轮”。该项目测试了三种可能的候选肽分子（一个在神经中，两个在血液中）是否以及如何控制这种“第二齿轮”，从而调节血压。

Blood pressure depends on nerve signals that travel from the central nervous system to blood vessels. In the middle of this pathway is a relay station - the sympathetic ganglion cell. Transmission through this relay station has recently been shown to have not only a fixed but also a variable component - the 'second gear'. The project tests if and how three likely candidate peptide molecules, one in the nerves, two in the bloodstream, control this 'second gear' and hence regulate blood pressure.
