| 520 | _ | _ | |a The rd10 mouse is a widely used model for degenerative retinal diseases such as retinitis pigmentosa(RP). Its retina shows rhythmic spontaneous activity at a frequency of three to seven Hz, andthe retinal ganglion cells (RGCs) are less electrically excitable. We hypothesize that the electricalexcitability can be improved by suppressing the oscillations using the neuroprotective drugs2-aminoethanesulphonic acid (taurine), brimonidine and betaxolol. These are involved in calciumhomeostasis and may play a crucial role in neuroprotection and excitotoxicity by preventing Ca2+overload. Spontaneous activity and responses to electrical stimulation of isolated retinas from3- to 4-month-old rd10 mice were recorded using multielectrode arrays. At defined times, theneuroprotectants were repeatedly added to the medium according to a standardized protocol toanalyze the reproducibility and reversibility of their effects. Taurine and betaxolol significantly reducedoscillations and bursting behavior and ameliorated electrical efficiency. Brimonidine only reduced thefrequency of oscillations. The effects on oscillation, spontaneous firing frequency, bursting behaviorand stimulation efficiency were reproducible and reversible. The drugs tested appear to be promisingtherapeutic candidates for improving the residual function of RGCs. They will be further investigatedand combined with other RP treatments, such as retinal prostheses, in the future. |
