Research Abstract |
We studied in this project whether and how calpains, calcium activated proteases, play roles in the photoreceptor apoptosis during retinal degeneration of retinitis pigmentosa model animals. We found that activities of mitochondrial calpains increased in the early stage of retinal degeneration of Royal College Surgeon's (RCS) rats. We also found that intravitreal injection of calpain inhibitors specifically retarded photoreceptor apoptosis.
