Peripheral neuropathy in the diabetic mutant mouse. An ultrastructural study.


Structural changes in peripheral nerves were studied sequentially in mutant diabetic mice. Axonal changes were found in both myelinated and unmyelinated fibers, the outstanding early change being the development of honeycombed Schwann cell-axon networks followed by axonal atrophy in both myelinated and unmyelinated fibers. In the late stages of the diabetic syndrome, this axonopathy was accompanied by secondary corrugated myelin breakdown. The changes, indicative of a primary axonal degeneration, are comparable to findings in human diabetic neuropathy for which this seems a suitable experimental model.
