Text

Retinitis Pigmentosa (RP) is an untreatable inherited retinal disease leading to blindness. The disease initiates with the loss of night vision due to rod photoreceptor degeneration, followed by irreversible progressive loss of cone photoreceptors death. Cone loss is responsible for the major visual handicap as cones are essential for day and high acuity vision. Their loss is indirect since most RP genes are not expressed by these cells. We have previously shown that factors secreted from rods are an essential requirement for cone viability. We now have identified one such trophic factor by expression cloning and named it rod-derived cone viability factor (RdCVF). RdCVF is a novel truncated thioredoxin-like protein (Txnl6) specifically expressed by photoreceptors. The identification of this protein offers new therapeutical possibilities for RP.
