This article examines anticytokine therapies for autoimmune diseases, highlighting the potential of anti-interferon-γ as a universal treatment for certain conditions and noting varying effectiveness of tumor necrosis factor-α inhibitors.

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 explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.

This review examines the current landscape of drug repositioning, highlighting that computational methods expand possibilities for reusing existing drugs to treat unmet medical needs. The authors discuss both the potential of these methods and the challenges faced in identifying new therapeutic applications.

This study demonstrated that vitamin B12 may promote hair growth in vitro by modulating intracellular signaling in the wnt-pathway, suggesting potential benefits for micrograft transplantation.

This systematic review and meta-analysis found 30 genetic loci associated with skin ageing phenotypes, noting shared biological pathways in aspects like pigmentation and wrinkling; researchers suggest further studies targeting the same SNP across populations could clarify these associations.

This study discusses the epithelial-immune microenvironment in chronic skin diseases, such as psoriasis and atopic dermatitis, and highlights current and future treatment strategies targeting inflammatory loops within these diseases.

This review discusses the association between emotional stress-related neuropeptides and the pathogenesis of alopecia areata, reporting no new experimental findings.

In this study, patients with alopecia areata showed significantly elevated serum levels of IFN-γ and severely deficient vitamin D3 levels compared to healthy controls.

In this study, researchers found that cytokine dysregulation linked to genetic background is present in both patients and healthy but genetically related individuals in two autoimmune skin diseases, Pemphigus vulgaris and Alopecia areata, suggesting that protective immune mechanisms may prevent disease manifestation in predisposed individuals.

This review highlights that T cells are crucial in regulating hair follicle regeneration and their disruption can lead to alopecia, providing insights into hair disorders related to T cell immune balance and hair follicle regeneration.

In this study, researchers identified unique prenatal lymphocyte features in human fetal skin, including proliferative naive T cells and memory-like T cells, which may influence antigen and allergen responses in utero and infancy.

This study examined dermatological conditions in people with multiple sclerosis and found nevus and hair diseases to be the most common, indicating the importance of comprehensive skin examinations for early diagnosis and treatment.

This study found that targeting both hormonal and immune pathways improved treatment outcomes in androgenetic alopecia patients with an under-recognized inflammatory component called PIILIF, which may contribute to treatment resistance.

This review integrates studies on mouse models and human clinical observations to highlight the role of immune cells in skin development and how their dysregulation leads to skin disorders, suggesting potential therapeutic pathways for skin regeneration.

This study conducted a meta-analysis of gene expression data from alopecia areata patients, identifying 5109 differentially expressed genes and highlighting enriched pathways like JAK-STAT signaling, providing insights into the disease's pathogenesis and potential treatment targets.

In this study, black wolfberry ferment was found to promote hair regrowth in mice with androgenetic alopecia by increasing hair weight, follicle count, and skin thickness, potentially through PI3K/AKT, NF-kappa B, and MAPK signaling pathways.

This review discusses how dysregulated levels of eicosanoids, which are metabolites of phospholipids, may contribute to skin diseases like psoriasis and atopic dermatitis, suggesting the importance of targeted eicosanoid control in diagnosis and treatment.

This study observed that topical application of maslinic acid stimulated hair growth in mice comparably to minoxidil, possibly through the Wnt/β-catenin pathway and involving ciliary gene activity, highlighting increased levels of trichogenic gene expression and protein levels.

This case study reports a young male with alopecia universalis experienced significant hair whitening following baricitinib treatment, highlighting the need for further research on JAK inhibitors' impact on hair pigmentation and their underlying mechanisms.

This study found that sleep deprivation in mice can trigger prostatitis by activating the cGAS-STING pathway due to reduced levels of dihydrotestosterone and melatonin, resulting in a pro-inflammatory environment, while recovery sleep can mitigate these effects.

This study examined the molecular communication in psoriasis cells, highlighting unique immune cell interactions and identifying new features of the hair follicle cell-psoriasis axis. It suggests the potential for targeted therapies at the single-cell level to improve psoriasis treatment.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.

This review explores how radiation-induced hair graying can be used as a model to study the mechanisms behind hair graying, focusing on cellular senescence and potential therapeutic targets to address age-related changes. Results are not provided.

This study found that garlic exosomes induced hair growth in rats by increasing anagen follicle counts and activating multiple signaling pathways, including Wnt-1, β-catenin, and TGF-β1.

This article reviews the pathogenesis, complications, and management of lichen planus, especially its persistent oral form, and highlights the need for further prospective studies.

This review discusses recent advances in the understanding of follicular melanogenesis and its pathological changes, particularly how these changes are associated with specific disease phenotypes, but it reports no new results.

This study identified non-structural proteins in preschool children's scalp hair that suggest potential biomarkers for brain development, immune function, and stress response with heritability and age-related differences.

This study found that hair-type tissues in hedgehogs show higher enrichment of immune-related genes compared to spine-type tissues, suggesting that spines evolved to protect against injuries and infections.

This study reviews drug-induced hair changes, noting that hair loss often reverses after stopping the drug, but permanent alopecia cases post-chemotherapy are rising.
