title: Developmental expression of nerve growth factor in the eye of rats affected by inherited retinopathy: correlative aspects with retinal structural degeneration.
abstract: We have previously reported that exogenous administration of nerve growth factor (NGF) in C3H/HeJ mouse strain affected by retinitis pigmentosa (RP) delayed retinal degeneration, suggesting that NGF may be implicated in retinal development. Whether NGF is present in the developing eye was not investigated. To address this question we have used Royal College of Surgeons (RCS) rats, characterised by photoreceptor loss during postnatal life. The results of these studies showed that while the thickness of the outer nuclear layer (ONL) of RCS is comparable to controls, while the amount of NGF expressed in the eye of this mutant rat is significant lower, as compared to control eye. This observation suggests that the lower presence of NGF in the eye of RCS rats during early postnatal life might be one critical key factor implicated in RP. The results of these studies will be presented and discussed.
