In this study, researchers observed that follicular damage and stem cell loss in frontal fibrosing alopecia may be mediated by immune attacks at the bulge region, suggesting potential for JAK/STAT-targeting treatments to prevent progression.

Targeting immune pathways like JAK/STAT may help treat frontal fibrosing alopecia.

This review explores the role of Granzyme B in autoimmune skin diseases and highlights its potential as a therapeutic target due to its involvement in impaired barrier function and inflammation.

This study demonstrated the expression of type 1 interferon-related proteins in inflammatory lesions of alopecia areata, showing a distinct distribution pattern compared to cicatricial alopecia.

This study found that pro-inflammatory cytokines and apoptotic mechanisms, specifically involving granzyme B and Fas pathways, are associated with chronic alopecia areata, indicating their potential role in the disease's persistence.

In this study, researchers using a Treg-specific HuR-deficient mouse model found that the RNA-binding protein HuR is crucial for stabilizing Foxp3 mRNA, affecting Treg function and immune regulation, with HuR disruption leading to impaired Foxp3 expression and potential autoimmune dysfunction.

This study found that oral administration of Flammulina velutipes polysaccharide reduced tumor volume and improved survival in mice by modulating macrophage polarization and enhancing antitumor immune responses.

This review explores the role of regulatory T cells in autoimmune skin disorders like alopecia areata and vitiligo, emphasizing unanswered questions and reporting no new experimental results.

This study found that bioelectric and biochemical signaling mechanisms coordinate collective cell movement during chicken feather bud morphogenesis, suggesting a potential new angle for research in skin development and wound healing.

This article reviews sebaceous immunobiology and highlights the complex role of sebaceous glands and sebocytes in skin barrier function and inflammation, particularly in acne pathogenesis, but reports no new results.

This review discusses the effects of valproic acid on immune cell activation and gene expression, potentially influencing infection outcomes and suggesting its promise for autoimmune and hypersensitivity condition management.

This review discusses sex-based differences in immune responses, focusing on genetic, hormonal, and microbiome factors influencing infections like COVID-19, and reports no clinical results.

This study found that increased metastatic ability in colorectal cancer in a rat model was linked to changes in expression of multiple genes, including TGF-beta, PDGFb, and Rho B.

This review examines the role of innate lymphoid cells in allergic diseases and the influence of an allergic microenvironment on their plasticity, without reporting new clinical outcomes.

This study suggests that dietary grape powder may reduce the severity of atopic dermatitis in a mouse model, highlighting its potential in both prevention and intervention settings.

In this study, researchers found that alopecia areata is linked to immune cell activation against hair follicle autoantigens and is associated with heart changes and cardiac marker alterations in humans and mice.

This review discusses the involvement of type I interferons in skin autoimmune and inflammatory diseases but reports no new clinical results.

This study suggests that hormone replacement therapy and oral contraception may have a protective role in scarring alopecia, as these were reported less frequently by patients with the condition compared to those with female pattern hair loss.

In this study, iNKT10 cells were found to play a significant role in preventing and treating alopecia areata in a humanized mouse model, suggesting these cells could have potential in managing related autoimmune disorders.

In this review, researchers discussed recent insights into caspases, enzymes initially associated with cell death and inflammation, revealing their broader roles in cell proliferation, migration, and differentiation, and highlighting the importance of caspase knock-out mice for understanding their implications in diseases.

In this narrative review, researchers outlined the role of T cells in the autoimmune pathogenesis of alopecia areata and highlighted ongoing research into therapeutic pathways, beyond current JAK inhibitors, aimed at developing new treatments for the disease.

This study found that in patients with alopecia areata, serum granulysin levels decreased significantly after treatment with tofacitinib and correlated with reduced disease severity, suggesting serum granulysin as an indicator of immunological activity and response to therapy.

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 the role of perifollicular regulatory T cells in maintaining hair follicle integrity in the context of hidradenitis suppurativa and calls attention to inflammatory mechanisms without reporting new clinical results.

This review explores the expression of Perforin by gamma delta T cells in human skin and its role in cytotoxicity but reports no new experimental results.

This study found that dihydrotestosterone (DHT) suppresses prostaglandin E2 and TGF-β induced IGF-I gene promoter activity in osteoblasts, suggesting complex interactions among bone growth regulators and potential complications from anabolic steroid use.

This study introduces stem cell activity as a key factor influencing the effects of IFN-γ and TGF-β1 on autoimmune disease dynamics, showing that varying cytokine levels can modulate stem cell activity and immune privilege, impacting tissue regeneration and disease flares.

This case report describes a 25-year-old woman with widespread lichen planus who did not respond to multiple systemic treatments, including antihistamines, hydroxychloroquine sulfate, and corticosteroids.

This study found that Sp6 overproduction in ameloblast-lineage cells increased cell proliferation and ameloblastin expression, suggesting that Sp6 promotes amelogenesis by inhibiting follistatin gene expression.
