Axonal transport of lectins in the peripheral nervous system
LF Borges and RL Sidman
The binding and axonal transport of six lectins were studied in the
peripheral nervous system of adult mice by an immunocytochemical method.
After injection into muscle and subcutaneous sites, lectins known to bind
preferentially N-acetylglucosamine or mannose sugars were transported
axonally to ventral horn and dorsal root ganglion neurons. Twelve to 96 hr
postinjection, these lectins were bound at the injection site to
neuromuscular junctions, muscle spindles, and cutaneous nerves. Lectins
known to bind preferentially N- acetylgalactosamine or galactose sugars, by
contrast, were transported only to dorsal root ganglion neurons. Except for
Sophora japonica agglutinin, these lectins were bound at the injection site
only to cutaneous nerves. These differences in axonal transport were seen
also when the lectins were applied directly to the proximal end of a
transected mixed nerve.
