For instance, in a dinitrochlorobenzene (DNCB)-induced AD-like mouse model, topical application of sea buckthorn oil ameliorated dermatitis severity, reduced epidermal thickness, and suppressed mast cell infiltration by inhibiting NF-κB, janus kinase 2/signal transducer and activator of transcription 1 (JAK2/STAT1), and p38-MAPK signaling, thereby reducing the production of T helper cell 2 (Th2) chemokines thymus and activation-regulated chemokine (TARC) and MDC (Hou et al., 2017). Here, JAK2 is linked to dermatitis.
