Ontogenesis of nicotinic acetylcholine receptors and presynaptic cholinergic neurons in mammalian brain.

abstract：:Retinitis pigmentosa is a very heterogeneous group of retinal degenerations, with multiple genes identified in each mode of inheritance. For autosomal dominant retinitis pigmentosa (ADRP), the most common gene is the rhodopsin (RHO) gene, mutations in which contribute to about 25% of ADRP in Caucasian population. To i...
