Preventing Age-Related Nuclear Cataract Development - Is Cholesterol the Key?

ABSTRACT: The cholesterol content in the membranes of the fiber cells of the human eye lens is significantly higher than in any other cell of the body. This review examines the existing literature on the origin and function of this unique feature as one of multiple factors that may help protect against age-related cataract formation throughout a person's life. Three independent sets of experimental data are highly suggestive that high cholesterol content in the fiber cell membranes may protect against cataract formation during aging: (1) saturating cholesterol content preserves the physical properties of the lipid bilayer of the lens cell membranes when the lipid composition of the bilayer changes; (2) high cholesterol content hinders the binding of cytoplasmic α-crystallin to the lipid membrane, wh
