Glycoprotein-deleted rabies virus (RABV ∆G) is a powerful tool for the analysis
of neural circuits. Here, we demonstrate the utility of an anterograde RABV ∆G
variant for novel neuroanatomical approaches involving either bulk or sparse
neuronal populations. This technology exploits the unique features of RABV ∆G
vectors, namely autonomous, rapid high-level expression of transgenes, and
limited cytotoxicity. Our vector permits the unambiguous long-range and
fine-scale tracing of the entire axonal arbor of individual neurons throughout
the brain. Notably, this level of labeling can be achieved following infection
with a single viral particle. The vector is effective over a range of ages (>14
months) aiding the studies of neurodegenerative disorders or aging, and infects
numerous cell types in all brain regions tested. Lastly, it can also be readily
combined with retrograde RABV ∆G variants. Together with other modern
technologies, this tool provides new possibilities for the investigation of the
anatomy and physiology of neural circuits.
