Аннотация
We report about changes on astrocytes in the facial nucleus of the rat following various types of peripheral nerve lesions. Astrocyte-specific glial fibrillary acidic protein (GFAP) was labeled by immunohistochemistry and served as a marker for these changes. Increased GFAP immunoreactivity was found in the facial nucleus on the lesioned side within 2-3 days after axotomy. This change lasted longer (up to 1 year) when axon regeneration was prevented or delayed by placing a metal clip on the proximal nerve stump. Lesion of the trigeminal nerve prior to axotomy reduced the degree of GFAP immunoreactivity. No side differences were observed after botulinum toxin application.
