Abstract:
The receptor for advanced glycation end-products (RAGE), a member of the immunoglobulin superfamily, is expressed in various cell types and mediates cellular responses to a wide range of ligands. The activation of RAGE triggers complex signaling pathways that drive inflammatory, oxidative, and proliferative responses, which are increasingly implicated in the pathogenesis of skin diseases. Despite its well-established roles in conditions such as diabetes, cancer, and chronic inflammation, the contribution of RAGE to skin pathologies remains underexplored. This review synthesizes current findings on RAGE's involvement in the pathophysiology of skin diseases, including conditions such as psoriasis, atopic dermatitis, and lichen planus, focusing on its roles in inflammatory signaling, tissue remodeling, and skin cancer progression. Additionally, it examines RAGE-modulating treatments investigated in dermatological contexts, highlighting their potential as therapeutic options. Given RAGE's significance in a variety of skin conditions, further research into its mediated pathways may uncover new opportunities for targeted interventions in skin-specific RAGE signaling.
