Outline of Final Research Achievements

BoNT/A heavy chain (Hc) was labeled with Thiol-Reactive Probes (Alexa-488) and injected into the dissociated rat trigeminal ganglion somata and the rat facial skin. Localization of BoNT/A-Hc was monitored in trigeminal ganglion neurons by confocal laser scanning microscopy.
BoNT/A-Hc was taken up by trigeminal ganglion neurons. This uptake was inhibited by colchicine treatment, which blocks axonal transport. Our data suggest that retrograde axonal transport of BoNT/A to sensory ganglion occurs following peripheral administration.
