Bioelectric Profiling of Atopic Dermatitis: From Molecular Barrier Defects to Closed‐Loop Theranostic Strategies

) that correlate positively with terminal differentiation proteins such as filaggrin, serving as a surrogate marker of molecular permeability. Concurrently, neuroselective CPT assessment reveals abnormal C-fibre sensitisation in non-lesional skin, distinguishing extrinsic from intrinsic AD phenotypes. Furthermore, we explore reciprocal interactions between bioelectric parameters, Th2/Th22 cytokines (e.g., IL-31, IL-13) and the microbiome. Finally, we discuss translating these signatures into closed-loop theranostic strategies for feedback-controlled drug delivery. This bioelectric panorama provides a unique biophysical perspective on AD pathogenesis and a theoretical foundation for future precision medicine.
