Application prospect of common viral tracers in study on brain effect of acupuncture / 中国针灸

ABSTRACT

The feasibility and prospect of viral tracers and mediating functional components are explored in study on brain effect of acupuncture. In the paper, proceeding with viral tracers, the viral tracers used to analyze the structure of specific neural circuits are introduced, as well as their mediated probes, optical/chemical genetics techniques, Cre-LoxP systems, etc. The viral tracers and their functional components can not only mark specifically nerve cells or neural circuits, but also interfere with the function of specific types of neurons or nuclei. They solve some disadvantage of traditional nerve tracing method that only describes the morphology of neurons of one brain region and the simple projection among brain regions, and the indirect and non-specific absorption. The viral tracers and their functional components play the important approach to decoding the mechanism on brain effect of acupuncture when introduced in experimental acupuncture so as to provide an in vivo, real-time and intuitive novel method for a further analysis of neurobiological mechanism on brain effect of acupuncture.
