Oxidation of two vicinal cysteines in interleukin-38 activates a redox switch, which exposes aggregation-prone sequences that drive amyloid formation. In this study, Diaz-Barreiro, Cereghetti et al. illuminate the molecular mechanisms behind this process and suggest its relevance to epidermal barrier function. The cover art represents this redox switch on the person’s skin, with city lights symbolizing the transition from IL-38 monomers (right) to amyloid fibrils (left). Image credit: Rémi Jeandenand.
