Alpha-crystallins and their derivatives have potential in preventing cell death, but chronic neurodegenerative diseases may lead to progressive loss of function in these proteins. Literature supports the anti-apoptotic potential of alpha-crystallins in retinal neurodegenerative diseases and explores the possibility of using these proteins to promote neuronal viability.
The chaperone and anti-apoptotic activity of alpha-crystallins (alpha A- and alpha B-) and their derivatives has received increasing attention due to their tremendous potential in preventing cell death. While originally known and described for their role in the lens, the upregulation of these proteins in cells and animal models of neurodegenerative diseases highlighted their involvement in adaptive protective responses to neurodegeneration associated stress. However, several studies also suggest that chronic neurodegenerative conditions are associated with progressive loss of function of these proteins. Thus, while external supplementation of alpha-crystallin shows promise, their potential as a protein-based therapeutic for the treatment of chronic neurodegenerative diseases remains ambiguous. The current review aims at assessing the current literature supporting the anti-apoptotic potential of alpha A- and alpha B-crystallins and its potential involvement in retinal neurodegenerative diseases. The review further extends into potentially modulating the chaperone and the anti-apoptotic function of alpha-crystallins and the use of such functionally enhanced proteins for promoting neuronal viability in retinal neurodegenerative disease.
