The Role of Caveolin-1 in Retinal Inflammation

Although the retina resides within the immune-protected ocular environment, inflammatory processes mounted in the eye can lead to retinal damage. Unchecked chronic ocular inflammation leads to retinal damage. Thus, retinal degenerative diseases that result in chronic inflammation accelerate retinal tissue destruction and vision loss. Treatments for chronic retinal inflammation involve corticosteroid administration, which has been associated with glaucoma and cataract formation. Therefore, we must consider novel, alternative treatments. Here, we provide a brief review of our current understanding of chronic innate inflammatory processes in retinal degeneration and the complex role of a putative inflammatory regulator, Caveolin-1 (Cav1). Furthermore, we suggest that the complex role of Cav1 in retinal inflammatory modulation is likely dictated by cell type-specific subcellular localization.
