December 2023 in “International journal of multidisciplinary research and analysis” This study suggests that administering SH-MSCs gel might decrease IL-6 expression and increase TGF-β expression in alopecia-like rats, indicating potential for alopecia therapy.
December 2023 in “International journal of multidisciplinary research and analysis” In this study, topical administration of secretome hypoxia mesenchymal stem cells gel increased IL-10 and decreased TNF-α gene expression in a fluconazole-induced alopecia-like model in rats, with the 40 μL dose having the most significant effect.
November 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” In this study, researchers found that ex vivo and in vivo administration of the TYK2 inhibitor BMS-986202 prevented immune privilege collapse and promoted hair regrowth in models of alopecia areata, suggesting this approach may offer a new therapeutic avenue deserving of clinical investigation.
April 2023 in “The journal of investigative dermatology/Journal of investigative dermatology” This study found that patients with alopecia areata had significantly lower frequencies of IL-10 producing CD19+CD24hiCD38hi regulatory B cells compared to healthy volunteers, suggesting a potential role for these cells in the autoimmune response seen in the condition.
