Interferon contributes to photosensitivity at least in part by causing Langerhans cell ADAM17 dysfunction, raising the possibility that anifrolumab ameliorates lupus skin disease in part by restoring Langerhans cell function.
A single-cell RNA profiling analysis has delineated the molecular changes driving the progression from actinic keratosis to cutaneous squamous cell carcinoma.
