Visual (retinoid) cycle anomalies induce aberrant build-up of all-trans retinal (atRAL) in the retinal pigment epithelium (RPE), which is a cause of RPE atrophy in Stargardt disease type 1 and age-related macular degeneration. NLR family pyrin domain containing 3 (NLRP3) inflammasome activation is implicated in the etiology of age-related macular degeneration. Here, we elucidated the relationship between NLRP3 inflammasome activation and atRAL-induced death of RPE cells.
