This study observed that individuals with Down syndrome exhibit early immune dysregulation, including multi-organ autoimmunity and hypercytokinemia, and found that the JAK inhibitor tofacitinib showed a good safety profile and reduced skin pathology in a Phase II trial.

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 Pannexin 3 plays a crucial role in skin development by regulating the transcription factor Epiprofin, affecting keratinocyte differentiation and hair follicle regeneration in mice.

Zeb2 is crucial for nerve repair by controlling Schwann cell function.

This study in mutant mice found that Bmpr2 and Acvr2a are individually redundant, but together essential for normal hair follicle development, with their reduction causing rapid hair cycling and graying.

This study found that keratin 14 may serve as an autoantigen in autoimmune skin diseases, indicated by its altered expression in affected skin and reactivity of patient sera.

This study found that an E-cadherin mutant preserved normal cadherin levels and prevented inflammation and lethality in mouse skin lacking p120, highlighting p120's role in regulating cadherin-mediated cell adhesion and inflammation.

This study found that Xinyang Tablet may improve cardiac function in LPS-induced sepsis-induced myocardial dysfunction by modulating macrophage polarization and autophagy through affecting LncSICRNT1 and TRAF6 expression.

This study identified a new subset of Ret-positive sensory neurons involved in itch perception, characterized by their unique expression profile and response to specific itch-inducing molecules.

This study found that KROX20 is crucial for hair follicle development and epidermal homeostasis, as its deletion in skin epithelial cells led to hair loss and increased epidermal thickness.

This study found that human adult dermal fibroblasts can express markers typically associated with neural cells, suggesting potential pitfalls in relying on immunophenotyping alone for cell identity verification.

In this case report, complete hair regrowth was observed in a patient with autoimmune-related alopecia areata after treatment with a Janus kinase inhibitor, suggesting its potential effectiveness for both genetic and sporadic forms of the condition.

Abatacept may help some people with alopecia areata regrow hair.

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.

In this study, tofacitinib treatment led to significant hair regrowth in 60% of patients with moderate-to-severe alopecia areata, suggesting potential for JAK inhibitors in treating this condition.

This study reports that AhR pathway expression is significantly reduced in lymphocytes of alopecia areata patients, suggesting its potential as a diagnostic marker and therapeutic target.

This research developed new in vitro models for high-throughput screening of drugs that could protect or restore immune privilege in hair follicles, finding that Tofacitinib was effective in preventing inflammation-related marker upregulation, while Tacrolimus and αMSH worked specifically in outer root sheath keratinocytes.

This study found that BMP-2 activates Dlx3 gene transcription in murine keratinocytes by binding with Smad1/Smad4, suggesting a mechanism for BMP signaling's role in skin and hair follicle regulation.

This review discusses the role of astrotactins in development and their genetic mutations' links to a variety of human diseases, but reports no new clinical results.

This study reports that a patient with rare linear lichen planopilaris experienced complete hair regrowth after 12 weeks of treatment with the antibody ixekizumab, suggesting it as a potential targeted therapy.

This study found that baricitinib was effective in regrowing eyebrow and eyelash hair in patients with severe alopecia areata, with similar improvements observed in both clinician-reported and patient-reported measures.

This letter reports a series of cases where the use of ruxolitinib at a lower dose than previously studied led to hair regrowth in patients with severe alopecia areata.

This study found that increased ACE2 expression, prompted by mechanical stretch, promotes skin regeneration and reduces dermal thinning during tissue expansion by enhancing collagen synthesis, suggesting ACE2's potential to improve clinical outcomes in reconstructive surgery settings.

This study found similarities in the regeneration processes of MRL mouse ears and axolotl limbs, involving G2 cell cycle arrest and nerve-dependent mitosis, but the role of p21 in axolotl limb regeneration remains uncertain.

In this study, baricitinib treatment led to significant regrowth of scalp, eyebrow, and eyelash hair in alopecia areata patients compared to placebo, with higher effectiveness seen at the 4-mg dose.

This study found that among various JAK inhibitors for severe alopecia areata, baricitinib_4 mg demonstrated significant efficacy with high precision, while deuruxolitinib_12 mg showed the best efficacy but with wider confidence intervals, providing clinicians valuable information for treatment selection.

This study found that keratin intermediate filaments in the hair of patients with giant axonal neuropathy were structurally altered, resulting in hair that was stiffer, stronger, and more extensible.
