IL-13 is a key cytokine in the development of AD, with miR-143 shown to be capable of regulating its receptor, IL-13Rα1, and preventing the IL-13-mediated dysregulation of proteins such as Filaggrin (FLG), Loricrin (LOR), and Involucrin (IVL), which are essential for the integrity of the skin barrier [107]. This evidence concerns the gene FLG and Alzheimer disease.
