Abstract :
[en] Auditory neurons depend upon the integrity of both their peripheral (auditory hair cells) and central (cochlear nucleus) targets for survival. One proposed trophic mechanism is the production of neurotrophin-3 (NT-3) by auditory hair cells. Modiolus-spiral ganglion explants from adult rats that closely mirror cell-cell interactions and in vivo tissue relationships within this ganglion provide a model for testing trophic factors. Brain derived neurotrophic factor (BDNF), NT-3 and ciliary neurotrophic factor (CNTF) were tested for their ability, both individually and in combination, to support neuronal survival. NT-3 was the strongest individual promoter of survival, while CNTF (a cytokine) with NT-3 (a neurotrophin) was the most effective combination for promoting the survival of auditory neurons.
