This study suggests that STAT3 signaling in keratinocytes is crucial for maintaining skin homeostasis by regulating hair follicle-specific keratin genes, potentially impacting dermatitis development through microbe-triggered inflammatory responses.

No results are provided in this article as it lacks an available abstract, making it unclear what effects apremilast and tofacitinib have in a humanized mouse model of alopecia areata.

This paper reviews the development and implementation of CAR-T cell therapy as a significant advancement in treating pediatric hematological malignancies, particularly for children with relapsed or chemotherapy-resistant acute lymphoblastic leukemia, offering renewed remission prospects where conventional methods are ineffective.

This review examines the scientific evidence on the short-term safety of testosterone therapy for treating hypoactive sexual desire disorder in women, without presenting new clinical results.

This study successfully optimized a culture strategy for dermal papilla cells and established an immortalized cell strain, iDP6, which is suitable for research and application.

In this study, researchers found that CD4 T cells from the skin draining lymph nodes of mice with alopecia areata can transfer the disease to recipient mice, highlighting the key role of these cells and their interaction with CD8 T cells in the disease's development.

In this study, Treg depletion impaired skin wound healing in mice, potentially by altering the cytokine environment and expanding certain T-cell populations, disrupting the normal healing process.

This study, using multimodal profiling in mice, found that various tissues contain unique γδ T cell subsets adapted to their environment, revealing their functional diversity, lineage relationships, and similarities to CD8+ tissue-resident memory T cells.

This study found that allergen treatment in alopecia areata mice appeared to alter leukocyte subset distribution and impaired dendritic cell migration, which may affect T-cell activation and hair follicle recovery.

This review discusses rodent models of alopecia areata and highlights genetic and epigenetic factors influencing its development, but reports no new experimental results.

CD8+ T cells attack hair follicle stem cells, causing scarring and hair loss in Discoid Lupus.

This study found that DNA-damaged hair follicle stem cells in mouse models do not show typical senescent markers but are dynamically expelled to maintain tissue health and prevent hair loss.

This study found that Wnt secretion is important for maintaining skin homeostasis in mice, as Evi-deficient mice developed psoriasis-like skin lesions and had an imbalance in immune cell populations.

In this study, single-cell sequencing revealed clonal expansions of CD4+ and CD8+ T cells in murine and human alopecia areata, supporting the development of predictive models for human disease.

This study proposes that intranasal exposure to PTx and autoantigen in an animal model can trigger autoimmune disease, supporting the idea that subclinical nasal colonization by BP may cause alopecia areata.

This study found that explant transfers of human umbilical cord Wharton's jelly-derived mesenchymal stem cells can yield cells for five consecutive times, optimizing primary cell production and reducing costs.

This review examines the interplay of genetics and neuroimmunology in alopecia areata, highlighting its potential to inform broader autoimmunity research, but reports no new findings.

This study investigated the impact of the JAK inhibitor ruxolitinib on APS-1 patients, reporting that treatment decreased excessive T-cell-derived interferon-γ, normalized inflammatory markers, and led to remission of several autoimmune symptoms without serious adverse effects.

This review discusses progress in targeted therapies for vitiligo, focusing on Janus kinase inhibitors and the potential of mesenchymal stem cells, but reports no new clinical results.

This manuscript reviews the latest understanding of alopecia areata's pathogenesis, highlighting the roles of genetic, immunological, and environmental factors, with a focus on immune responses involving IFN-γ and cytotoxic CD8+ T-cells as key contributors to hair follicle inflammation and function disruption without follicle destruction.

In a preclinical mouse model, this study found that early treatment with the selective SYK inhibitor entospletinib significantly improved survival rates and clinical outcomes for graft-versus-host disease after hematopoietic stem cell transplantation compared to placebo.

This study found that increased intracellular expression of thymosin β4 is necessary and sufficient to induce PAI-1 gene expression in endothelial cells, potentially mediated through Ku80 as a novel receptor.

This study found that immune cells, including T cells and macrophages, significantly influence stem cell behavior and tissue regeneration by secreting cytokines and inflammatory factors in mice.

This study reported that using UVB preirradiation and anti-CD154 antibody treatment in a humanized mouse model prolonged hair follicle allograft survival and reduced immune cell infiltration without needing generalized immunosuppression.

D-chiral biomaterial scaffolds enhance tissue and hair regeneration by activating the body's immune system.

This report details a case study where a 40-year-old woman experienced allergic contact dermatitis and angioedema-like symptoms after using PPD-containing hair dye. Patch testing confirmed a positive reaction to PPD, highlighting the substance's potential to cause both T-cell and IgE-mediated hypersensitivity reactions.

This review discusses the complexity of identifying hair follicle antigens involved in alopecia areata and reports no new clinical results, emphasizing the need for further research on autoantigen identity.

This study suggests that low-dose IL-2 and IL-15 may help restore immune tolerance in alopecia areata by maintaining Treg cell function, presenting a potential new treatment strategy.

ITK inhibitors may effectively treat alopecia areata.

This source does not report original research findings but reviews the mechanisms and challenges of immune response and immunosuppressive management in liver transplantation.
