This study found that umbilical cord-derived CD146+ MSCs showed a stronger ability to improve ovarian function and modulate immune responses in a mouse model of premature ovarian failure compared to CD146- MSCs, though both subpopulations effectively repaired reproductive ability.

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.

In this study, hair follicle-derived mesenchymal stromal cells showed potential for immunomodulation, with equivalent or superior responses compared to those from adipose tissue, suggesting a promising alternative cell source.

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.

This narrative review highlights the shared immunopathogenesis of alopecia areata and atopic dermatitis and discusses approved and investigational therapies that target common pathways, suggesting a future for personalized treatment strategies.

This study reports a case where cyclosporine effectively treated a 51-year-old woman with idiopathic follicular mucinosis resistant to other therapies, suggesting its potential as an option for refractory cases.

This review discusses recurrent implantation failure (RIF) in IVF, noting the lack of standard definitions or treatment protocols, and emphasizes the need for individualized treatment and further research.

In this study, researchers observed that a hidden scalp condition could contribute to acne keloidalis nuchae and potentially other primary cicatricial alopecias, impacting their diagnosis and treatment.

This review discusses the pathogenesis of alopecia areata, highlighting the role of immune privilege collapse in hair follicles but reports no clinical results.

This study found that the MD-3 antibody significantly improved the survival of hair follicle allografts in nonhuman primates by reducing T-cell infiltration.

This review discusses mechanisms of wound healing impairment in leptin-deficient murine models used for diabetic research, and reports no new clinical results; the authors emphasize the need for further study.

This review examines integrins as pharmacological targets, discussing current integrin-based therapies and emphasizing the need to understand integrin mechanisms for successful drug development, without reporting new clinical results.

Alopecia areata is an autoimmune disorder causing hair loss, linked to specific hair follicle antigens and genetic factors.

In this study, researchers found that hair follicle stem cells activate an immune-modulatory program during wound healing, promoting Treg cell expansion and aiding skin repair, while deleting certain immune components impaired healing and increased inflammation in a mouse model.

In this study, researchers investigated the immunohistopathological characteristics of the skin in individuals during the acute phase of chikungunya infection, revealing CHIKV antigens and inflammatory infiltrates in various skin components and highlighting the role of cytokines/chemokines in the disease's skin manifestations.

In this study, researchers reported that a newly developed interferon-γ release assay for cell-mediated immunity to SARS-CoV-2 nucleocapsid peptides demonstrated high sensitivity and specificity, making it a robust tool for routine diagnostic tests and potentially useful in predicting clinical outcomes after pathogen re-exposure.

This review summarizes recent findings about the multi-site differentiation of tissue regulatory T cells, emphasizing the pivotal role of epigenetic remodeling, but it reports no new clinical results.

This study found that acute stress can cause rapid hair loss by triggering necrosis in hair follicle cells and initiating autoimmunity, revealing a mechanism where stress-induced nerve activity leads to tissue damage and immune system activation.

This study found that selectively targeting HDAC4 and HDAC7 in mice can reduce Th17 cell-mediated intestinal inflammation, suggesting a potential treatment approach for Th17-related inflammatory diseases like ulcerative colitis.

This review explores the hair follicle microbiome's interaction with the immune system, discussing its potential clinical implications for scalp health and disease but reports no new clinical results.

This review explores the current and experimental therapies for chronic wounds, emphasizing the potential of cellular and immunotherapies in addressing these persistent conditions, but notes a shortage of comprehensive studies on their effectiveness.

iNKT cells help develop and maintain healthy skin in young mice.

This review discusses the various factors implicated in the etiology of frontal fibrosing alopecia and notes the need for effective treatments, reporting no new clinical findings.

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.

This review explores how mesenchymal stem cells and their extracellular vesicles may treat various skin diseases by modulating immune responses and promoting healing, though further clinical trials are needed to confirm their safety and efficacy in practice.

In this single-cell transcriptomic study, researchers analyzed AA scalp samples and found distinct immune and nonimmune cell activation patterns, with elevated TH1/TH2 and JAK/STAT markers potentially contributing to hair follicle immune privilege disruption and disease severity.

This review analyzed literature on primary cutaneous lymphomas involving the scalp, finding that scalp involvement in these cases often leads to non-scarring focal alopecia and may indicate more aggressive disease.

This narrative review explored the complex interconnections between psoriasis and other dermatological conditions like vitiligo, alopecia areata, and atopic dermatitis, highlighting shared immune dysfunctions that complicate diagnosis and treatment, with implications for research and holistic patient care.

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 identified Th22 cells as key effectors in hair regeneration driven by thymosin beta 15, suggesting they could be potential targets for hair regrowth therapies.
