Decreased neurofilament gene expression is an index of selective axonal hypotrophy in ageing.

Abstract:

:Axonal atrophy may reflect earlier and more reversible events in neurodegeneration and ageing than somatic atrophy. Innervation density by sympathetic fibres from the rat superior cervical ganglion (SCG) to the middle cerebral artery (MCA) decreases dramatically in old age, while that to the iris is largely unchanged. In situ hybridization was used in conjunction with retrograde tracers to examine the role of the neuronal cytoskeleton in this selective axonal vulnerability. Using a riboprobe complementary to neurofilament light chain (NF-L) mRNA, there was a 22-25% decrease in the mean grain density in aged neurones when all neurones were examined. A small subset of these neurones was shown to project to the MCA and another to the iris. In young SCG, both subpopulations expressed intermediate grain densities for NF-L mRNA. In MCA-projecting neurones, there was a 40% decline in grain density with ageing (p < 0.05), with no change in iris-projecting neurones. Our results demonstrate that major decreases in NF-L expression may represent cellular markers of selective axonal hypotrophy by aged neurones.
