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.

This study found that 3-Deoxysappanchalcone may stimulate hair growth in mice by promoting proliferation of hair follicle dermal papilla cells through WNT/β-catenin and STAT signaling modulation.

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.

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.

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.

This review discusses the potential of JAK inhibitors as a promising treatment strategy for alopecia areata, highlighting their mechanism and recent FDA approval based on clinical trial efficacy.

In this case report, the authors describe a child with treatment-resistant alopecia areata who successfully responded to leflunomide and anthralin, proposing this combination as a potentially cost-effective alternative for managing recalcitrant cases by possibly inhibiting the JAK/STAT pathway.

This study found that miRNA-24 downregulates the KLF6 gene, influencing coat color by affecting melanogenesis pathways in Cashmere goats, and that miRNA-24 inhibition increased melanin content in mice.

This review examines targeting the JAK-STAT pathway in inflammatory skin diseases, highlighting existing JAK inhibitors and potential developments, but presents no new experimental or clinical results.

In this study, a novel homozygous mutation in the STAT5B gene was identified in a 17-year-old boy with growth hormone-refractory growth failure, severe eczema, and autoimmune disease, suggesting a similarity to known STAT5B deficiency phenotypes.

This review discusses the molecular mechanisms and therapeutic effectiveness of Janus Kinase Inhibitors for inflammatory skin diseases, suggesting these inhibitors have a rapid onset and favorable safety profile compared to conventional treatments.

This study found that a lotion containing specific plant extracts significantly increased the number of anagen hairs and the anagen/telogen ratio in subjects with androgenetic alopecia after three months of use.

This review discusses the composition, activation, and regulation of the JAK/STAT pathway and highlights its role and inhibitors in various diseases, but reports no new experimental results.

This review discusses the role of the JAK-STAT pathway in autoimmune skin diseases and suggests potential therapeutic benefits of JAK inhibitors, but reports no new experimental results.

This study found that FLCN deficiency in mice muscles led to increased mitochondrial biogenesis and a metabolic shift towards oxidative phosphorylation, with a similar advantage observed in FLCN-null kidney cancer cells.

This review discusses the role of lysophosphatidic acid in skin physiology and pathology, highlighting its significance in processes like wound healing and hair follicle development, but reports no new clinical findings.

This study found that preconditioning adipose-derived stem cells with HB-EGF enhanced their ability to promote hair growth in vivo by increasing their motility, paracrine effects, and survival.

This study suggests that mesenchymal stem cell therapy may improve cell viability and regulate key signaling pathways in vitro for treating alopecia areata.

This study found that human hematopoietic mesenchymal stem cells increased the viability and migration of human outer root sheath cells in an in vitro alopecia areata model, involving Wnt/β-catenin and JAK/STAT pathways.

This review discusses the JAK-STAT pathway and the use of FDA-approved JAK inhibitors for autoimmune and inflammatory diseases but reports no new research findings.

This review examines clinical data on the efficacy and safety of JAK inhibitors used for immune-mediated conditions beyond rheumatoid arthritis, highlighting their potential therapeutic roles in various inflammatory diseases.

This study reported that inhibiting the JAK-STAT pathway with baricitinib restored cellular homeostasis, delayed senescence, and reduced proinflammatory markers in Hutchinson-Gilford progeria syndrome cell models.

This study reviewed the role of the JAK/STAT signaling pathway in skin diseases and the potential of JAK inhibitors for treating conditions like psoriasis and atopic dermatitis. Although the findings are promising, the authors concluded it is premature to establish their place in dermatological treatments.

This study found that human outer root sheath cells express VEGF receptor-2, and exogenous VEGF165 significantly stimulates their proliferation through activation of the ERK signaling pathway.
