The context is the biology of aging and retinal diseases. The interest is for cellular and molecular pharmacology, especially for the Nrf2 factor and the RNA-binding ELAV proteins (both gene expression regulators, acting at transcriptional and post-transcriptional level, respectively). The aim is to understand the roles of these proteins in physio-pathological contexts. The research includes the pharmacological modulation of Nrf2 and ELAV as potential therapeutic targets in age-related ocular pathologies.
