Several neuroinvasive viruses can be used to study the mammalian nervous system. In particular, infection by pseudorabies virus (PRV), an alpha-herpesvirus with broad host range, reveals chains of functionally connected neurons in the nervous systems of a variety of mammals. The specificity of PRV trans-neuronal spread has been established in several systems. One attenuated strain, PRV-Bartha, causes a reduced inflammatory response and also spreads only from infected post- to pre-synaptic neurons. We review the basics of PRV tracing and then discuss new developments and novel approaches that have enabled a more detailed understanding of the architecture of the nervous system. As questions and techniques evolve in the field of neuroscience, advances in PRV tracing will certainly follow.
几种具有神经侵袭性的病毒可用于研究哺乳动物的神经系统。特别是,伪狂犬病病毒(PRV)感染,一种具有广泛宿主范围的α疱疹病毒,可揭示多种哺乳动物神经系统中功能相连的神经元链。PRV跨神经元传播的特异性已在多个系统中得到证实。一种减毒株,PRV-Bartha,引起的炎症反应减弱,并且仅从受感染的突触后神经元传播到突触前神经元。我们回顾了PRV追踪的基础知识,然后讨论了新的进展和新方法,这些进展和方法使我们能够更详细地了解神经系统的结构。随着神经科学领域问题和技术的不断发展,PRV追踪的进展必将随之而来。
