This study demonstrates that T-cell responses in extensive alopecia areata scalp may be aberrantly regulated, with reduced cytokine production but activated phenotype, providing insight into the disease's immune mechanisms.

The authors discussed that SOCS1 and SOCS3's inhibition of JAKs plays a significant role in the development of JAK inhibitor drugs for skin inflammatory diseases and malignancies.

This review discusses how chronic inflammation can lead to persistent stem cell activation and DNA damage, ultimately promoting cancer development and metastasis, but reports no new results.

This review explores the role of Tregs in autoimmune skin diseases, transplantation, and skin cancer, and discusses Tregs-based therapies' potential for treating autoimmunity without reporting new experimental results.

In this review, the authors reported that sprout extracts, rich in bioactive compounds, show promising effects on skin health, such as enhancing collagen synthesis, improving hydration, and reducing inflammation, though most evidence comes from laboratory and animal studies.

This study developed a hydrogel microneedle system combining ginseng-derived exosomes and biomimetic nanoparticles to address oxidative stress, inflammation, and melanocyte deficiency in vitiligo, showing significant repigmentation in mice within 3 weeks by enhancing melanocyte protection and keratinocyte proliferation.

In this study, authors present a case where a 26-year-old patient with alopecia areata experienced relapse after initially responding to Tofacitinib, mitigated by corticosteroids, highlighting challenges and potential insights into the treatment and pathogenesis of the condition.

The study investigated immune cell patterns around the hair follicle infundibulum in androgenetic alopecia, revealing significant differences in immune signatures between patients with AGA and control donors, specifically noting an enrichment of CD4 cells in the patient group.

This review discusses the potential of P. polyphylla saponins to treat acne through antibacterial, anti-inflammatory, immunomodulatory, and antioxidant effects, noting that acne's complex pathogenesis makes this line of research promising for future studies.

This review explores the emerging roles of NK cells in various diseases, including allergies and skin conditions, and reports no new clinical results while indicating NK cell involvement in immune processes.

This review discusses the roles of androgens and androgen receptor in skin diseases like acne and hirsutism, and highlights the promise of antiandrogen drugs, reporting no new clinical findings.

This review discusses sex differences in immune responses and highlights mechanisms involving sex hormones, X-linked genes, and X-Chromosome Inactivation, but reports no new clinical findings.

PDE inhibitors, especially PDE4 inhibitors like apremilast, are effective for certain inflammatory skin conditions but have side effects and can be costly.

This study found that kaempferol increased the proliferation potential of basal epidermal cells in three-dimensional skin models by enhancing integrin expression and altering cell morphology.

This study found that elevated STAT5 levels are linked to improved hair-inducing capabilities in human dermal papilla cells, and reducing STAT5 impairs hair follicle induction.

This study found that treating human dermal fibroblast cells with ginsenoside Rd increased the expression of mRNA associated with the dermal-epidermal junction, suggesting potential as an anti-aging cosmetic ingredient.

This study found that TGFbeta is a key pathway causing age-related loss of dermal fat's antimicrobial function, suggesting that targeting TGFBR might help restore skin defense against infections in older age.

This study found that the absence of Hes1 in hair follicles delays secondary hair germ activation and shortens the anagen phase, impacting HFSC self-renewal and long-term hair regeneration.

Pimecrolimus cream is not effective for treating alopecia areata.

This review discusses recent advances and ongoing clinical trials in novel therapeutics for alopecia areata, despite the lack of current FDA-approved treatments for severe cases, and reports no new results.

This review suggests that decreased serum 25-hydroxyvitamin D levels may play a role in different types of non-scarring alopecia, but further studies are needed to explore vitamin D supplementation as a therapeutic option.

This study found that topical ginsenoside Rg1 may protect skin from UVB-induced damage in mice by reducing pathological changes and modulating cytokine mRNA expression associated with inflammation and immune response.

This study observed that pantethine, a vitamin B5 precursor, attenuates tumor growth in immunocompetent mice by enhancing antitumor immunity, but its effect is limited by immune cell exhaustion over time.

This study reports that 71% of patients treated with the gamma-secretase inhibitor PF-03084014 for desmoid tumors experienced dermatologic side effects, such as follicular lesions and pruritic eruptions, which were managed with topical or systemic treatments.

This article reviews treatment options for cutaneous T-cell lymphoma, including skin-directed therapies and aggressive treatments for advanced cases, but reports no new clinical results.

This case report observed that oral tofacitinib treatment resolved both alopecia universalis and plaque psoriasis in a patient, possibly by targeting shared inflammatory pathways.

This study observed that dupilumab led to significant hair regrowth and was well-tolerated in children with both alopecia areata and atopic dermatitis, showing promise as a safe treatment option for pediatric patients with associated atopy.

This case report describes a 21-year-old woman with progressive alopecia areata who experienced hair regrowth while treated with tocilizumab for posterior uveitis, suggesting the potential for this drug to affect hair loss and regrowth by disrupting interleukin-6 signaling.

This review discusses the roles of the hairless (HR) protein as a corepressor, particularly its impact on RORα-mediated transcriptional repression, and reports no new experimental findings.

This study explores the potential of platelet-rich plasma (PRP) as a novel adjuvant therapy for eczema, positing that it may alleviate inflammation, enhance skin barrier function, and reduce recurrence.
