Abstract
Glial fibrillary acidic protein (GFAP) increases in astrocytes following axotomy of facial motoneurons. In the present study we quantified GFAP synthesis both in regenerating facial nuclei after nerve crush and in nonregenerating facial nuclei after nerve resection. An increase in GFAP synthesis during regeneration occurs as early as 24 h after the axotomy. Thus, the increase in the astrocytic GFAP synthesis seems to be the earliest glial response to retrograde changes in facial motoneurons.
