Degeneration and Ageing

Cellular aging means the progressive decline of several molecular mechanisms that protect DNA, proteins, and organelles from damage, resulting in a gradual loss of cellular functions and ultimately in cell death. 

Our group's goal is to investigate the molecular mechanisms of aging that lead to degeneration in age-related diseases of the retina, with a particular emphasis on proteostasis. Our purpose is to use that knowledge to develop new therapeutic approaches for early interventions on diseases such as diabetic retinopathy and age-related macular degeneration.

As models, we use human-based cellular models, retinal porcine explants, and retinal organoids. Also, we work to translate our findings to the clinics in close collaboration with ophthalmologists and involvement in clinical studies and clinical trials.
