Human Retinal Pigment Epithelium Cell Changes and Expression of αB-Crystallin

The detection of alphaB-crystallin in the RPE of patients with early and advanced AMD implicates this as an AMD biomarker. Sporadic expression of alphaB-crystallin by RPE cells localized adjacent to drusen in early AMD indicates that changes in the gene expression of RPE cells accompany early stages of the disease and introduces novel potential targets for AMD therapy.
