Cell Death Mechanisms

Comparative analysis of cell death associated enzymatic activities in ten different models for retinal degeneration.

A very interesting aspect of our research is that most of the biochemical processes we found to be involved in photoreceptor neurodegeneration are not normally associated with established cell death mechanisms such as apoptosis or necrosis. We believe that we may instead be facing a novel form of cell death that could be highly relevant not only for photoreceptors but also for many other types of neurodegenerative diseases. The retina could provide us with unique possibilities to study and further elucidate such a novel cell death mechanism.
