March 2026 in “Journal of Translational Autoimmunity” In this study using a mouse model with alopecia areata, the researchers found that ruxolitinib enhances hair regrowth by inhibiting the JAK-STAT signaling pathway, reducing inflammation and oxidative stress, and decreasing apoptosis, which supports its clinical effectiveness in treating this condition.

December 2018 in “International journal of environmental research and public health/International journal of environmental research and public health” This study observed that Epigallocatechin-3-gallate (EGCG) can inhibit phosphorylation of STAT1 and reduce a specific subset of immune cells in vitro and ex vivo, suggesting a potential role in maintaining immune privilege in alopecia areata.
May 2024 in “Archives of dermatological research” This study found that Enz_MoriL, a compound derived from Morus alba L., promotes hair follicle cell proliferation by affecting the Wnt/β-catenin pathway and can counteract an alopecia areata-like condition by suppressing the JAK-STAT signaling in human hair follicle dermal papilla cells.
July 2026 in “Experimental Dermatology” In this study, researchers found that minoxidil sulfate enhances the anti-inflammatory effects of the JAK inhibitor baricitinib in alopecia areata, modulating inflammatory signals and preserving immune privilege features in human hair cells, which suggests potential benefits for combined therapy.
