title: The effect of axon injury on microtubule-associated protein MAP2 mRNA in the hypoglossal nucleus of the adult rat.
abstract: High molecular weight microtubule-associated protein 2 (HW MAP2) is heavily concentrated in mature dendrites and may be critical for dendritic stability. Motor axon injury results in retraction of the dendritic tree which is associated with a decrease in MAP 2-like immunoreactivity (-LIR). Here we have shown with in situ hybridization that motor axon injury results in reduced expression of HW MAP2 mRNA in affected neurons. We conclude that axotomy induces a down-regulation of HW MAP2 synthesis.
