Retrograde infection of recombinant vesicular stomatitis virus (VSV) missing the glycoprotein (G) gene from its genome, but pseudotyped with the wild-type VSV-G [rVSVΔG(VSV-G)]. VSV infect the neurons via axon terminal. (A) A cartoon showing the dorsal view of the X. laevis brain with the unilateral injection of rVSVΔG(VSV-G) into the left anterior laryngeal motor nucleus (n.IX-X). (B) Nine days after injection, labeled somata with lateral axonal projections were found in ipsilateral dorsal tegmental area of medulla (DTAM). (C) In the contralateral DTAM, there were no labeled neuron somata but some labeled processes (white arrow heads). (D) Left n.IX-X injected with rVSVΔG(VSV-G) shows a large number of labeled neurons. (E) The contralateral n.IX-X show no labeled neurons, but labeled axons are seen (white arrow heads).
