Following a nerve crush, cholesterol from degenerating myelin is retained within the nerve and reutilized for new myelin synthesis during nerve regeneration, apparently via a lipoprotein-mediated process. Because at least some serum components have access to the endoneurium of injured nerve, it has been suggested that serum lipoproteins are also significant contributors of cholesterol to Schwann cells during nerve regeneration. To test this hypothesis, serum cholesterol levels were reduced by > 90% with 4-aminopyrazolopyrimidine, followed by measurement of the activity of the key regulatory enzyme in cholesterol synthesis, 3-hydroxy-3-methylglutaryl-CoA reductase. Treatment with 4-aminopyrazolopyrimidine caused a sevenfold increase in 3-hydroxy-3-methylglutaryl-CoA reductase activity in kidney but had no effect on the activity of this enzyme in either intact or regenerating sciatic nerve. These data indicate that serum-derived cholesterol is neither necessary for nor contributes significantly to myelin synthesis in regenerating nerve.
