Age-related macular degeneration (AMD) is the leading cause of vision loss in Western world, and it currently lacks effective therapy. It believed that AMD initiates aged retinal pigment epithelium (RPE), which presents lysosomal dysfunction oxidative stress (OxS) ultimately leads to RPE damage progression. a complex pathology, so multitarget treatments are required act on different pathways, presenting several challenges. In this review, we discuss current knowledge pathogenesis disease, focusing mainly OxS. Because transcription factors regulate homeostasis, factor EB (TFEB), controls function biogenesis, nuclear erythroid 2-related 2 (NRF2), manages OxS, have been proposed as promising targets for disease intervention. Finally, interplay these pathways potential synergistic effect AMD-targeted therapies, they could change course today’s available AMD.

Retinal pigment epithelium (RPE) cells are important fundamentally for the development and function of retina. In this regard, study morphological molecular properties RPE cells, as well their regenerative capabilities, is particular importance biomedicine. However, these studies complicated by fact that, despite external similarity a population heterogeneous genetic which have begun to be revealed sequencing methods only in recent years. This review carries out an analysis data from heterogeneity mammals humans, reveals individual differences subpopulations possible specificity functions. Particular attention paid discussing "stemness," proliferation, plasticity RPE, may useful uncovering mechanisms retinal diseases associated with pathologies finding new ways treating them.
