Ocular diseases and truncated thioredoxin rod-derived cone viability factor: A strategic presentation by Pr Thierry Léveillard

Dr Thierry Léveillard from the Department of Genetics at Institut de la Vision MR-S 968, Paris will give a presentation about the nucleoredoxin-like 1 gene encodes for two proteins that contributes to a super-thioredoxin system during Paris Redox World Congress 2017.

In this presentation, Dr Léveillard will highlight the following points:

1) The nucleoredoxin-like 1 (NXNL1) gene encodes for two proteins by alternative splicing, the truncated thioredoxin rod-derived cone viability factor (RdCVF) that acts as a trophic factor for cone photoreceptors and the active thioredoxin RdCVFL that protects photoreceptors, both rods and cones.

2) The NXNL1 signaling is a promising neuroprotective therapy of inherited retinal diseases

3) RdCVF secreted by rods stimulates glucose uptake by cones through its interaction with the complex made of basigin-1 and GLUT1 at the surface of the cones, RdCVFL prevents oxidative damage to the cones in a cell autonomous manner.

4) The results in a mouse model of blindness indicates that increased glucose uptake in cones by RdCVF is used in part to provide redox power to RdCVFL via the pentose phosphate pathway.
