In the mammalian retina, light signals generated in photoreceptors are passed to bipolar and horizontal cells via synaptic contacts. In various pathological conditions, these second-order neurons extend neurites into the outer nuclear layer (ONL). However, the molecular events associated with this neurite outgrowth are not known. Here, we characterized the(More)
Retinitis pigmentosa (RP) is a group of genetically heterogeneous, severe retinal diseases commonly leading to legal blindness. Mutations in the CNGB1a subunit of the rod cyclic nucleotide-gated (CNG) channel have been found to cause RP in patients. Here, we demonstrate the efficacy of gene therapy as a potential treatment for RP by means of recombinant(More)
Cell death in neurodegenerative diseases is often thought to be governed by apoptosis; however, an increasing body of evidence suggests the involvement of alternative cell death mechanisms in neuronal degeneration. We studied retinal neurodegeneration using 10 different animal models, covering all major groups of hereditary human blindness (rd1, rd2, rd10,(More)
The general effects of castration, in addition to the loss of spermato-genesis, have been known since our earliest historical records. It is not the purpose of this paper to review the earlier studies which emphasize the effects of castration of the male, of transplantation of gonads, and of cryptorchidism on the various physiological, psychical,(More)
