title: A specific 37,000-dalton protein that accumulates in regenerating but not in nonregenerating mammalian nerves.
abstract: A 37-kilodalton protein is synthesized at higher rates in the peripheral and central nervous system of newborn rats than in adult animals. As a specific response to denervation, the synthesis of the 37-kilodalton protein is increased in the mature peripheral and central nervous system; however, this protein accumulates only in the peripheral nervous system. The differences in accumulation of the protein correlate with the apparent differences in the ability of peripheral and central axons to regenerate. The synthesis of the 37-kilodalton protein is inhibited when proper innervation or reinnervation is established.
