Ebastine may help regrow hair in alopecia areata patients.

This article reviews the epidemiology, clinical evaluation, and pathogenesis of alopecia areata and highlights recent advancements, but it does not report new clinical findings.

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.

This study suggests that SOCS3 treatment may effectively inhibit alopecia areata by suppressing CD8+ T cell activity and IFN-γ production.

This study found that Ifidancitinib, a JAK1/3 inhibitor, significantly promoted hair regrowth and reduced inflammation in a mouse model of alopecia areata by decreasing pathogenic T cell activity and inducing T cell exhaustion.

In this case report, two plywood mill workers developed allergic contact dermatitis due to exposure to uncured phenol-formaldehyde resin, not sawdust as initially suspected.

Alopecia areata is caused by an immune response, and targeting immune cells might help treat it.

This study found that immune-mediated destruction of bulge stem cells is a key factor in the alopecia observed in AE mice, suggesting it as a model for studying primary cicatricial alopecias, particularly lichen planopilaris.

This review discusses how urban air pollutants may influence the regulation of JAK3 signaling in alopecia areata and reports no new experimental results; the authors integrate existing data to map potential pathways and biomarkers.

This case report suggests that frontal fibrosing alopecia with nail involvement may be associated with lichen planus and improved with oral dutasteride due to an inflammatory reaction related to androgenetic 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.

This review highlights recent insights into how IL-15 influences T cell responses and contributes to immunopathogenesis in various diseases, suggesting its crucial role in TCR-independent activation and potential in optimizing therapeutic strategies.

In this study, gene expression analysis of plucked hair follicles from scalp lesions was sufficient to differentiate chronic discoid lupus erythematosus from psoriasis and healthy controls, suggesting a non-invasive diagnostic potential.

This study found that applying topical imiquimod during mid and late telogen in mice activates hair follicle stem cells and influences immune cell infiltration, promoting hair cycle entry independently of Wnt signaling.

This review discusses the pathogenesis and challenges in treating primary cicatricial alopecia, highlighting the need to understand immune protection collapse in hair follicle stem cells; it reports no new clinical results.

This study found that alopecia areata is linked to genetic factors, specifically HLA haplotypes on chromosome 6, and involves immune privilege collapse at hair follicles which is mediated by the JAK-STAT pathway and pro-inflammatory cytokines like IFN-γ.

This review summarizes recent advances in Treg cell biology, focusing on Foxp3's role in immune regulation and therapeutic reprogramming for immune dysregulatory disorders, but reports no new clinical results.

This review discusses the similar immune pathways and genetic risk factors of vitiligo and alopecia areata but reports no new clinical findings, emphasizing the potential for shared treatment research.

This study identified key genetic regions associated with alopecia areata, highlighting both acquired and innate immune involvement, with a novel link to the upregulation of ULBP ligands in autoimmune disease.

This study found that B6.CD80CD86−/− mice developed autoimmune-like alopecia with nearly 100% incidence by 40 weeks, making them a promising model for studying human alopecia areata.

This study found that disrupting inflammasome signaling by eliminating caspase-1 and -11 in mice reduced skin inflammation and delayed the onset of disease, highlighting their role in skin disease pathogenesis.

This study demonstrated that disrupting EGFR signaling in mice leads to immune sensitivity compromising the hair follicle's protective environment, but JAK1/2 inhibition can restore this immune privilege and stimulate hair growth, suggesting a potential therapy for scarring hair loss diseases like cicatricial alopecia.

This review discusses the bidirectional interactions between human mast cells and CD8 T cells in the skin, particularly in the context of disorders like psoriasis, atopic dermatitis, and vitiligo, and reports no new findings.

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.

This review discusses the complex causes and treatment challenges of chronic inflammatory skin diseases, emphasizing the need for biomarkers to predict treatment responses; it reports no new clinical results.

This study developed a technique to limit genetic recombination to regulatory T cells to investigate whether self-tolerance is maintained in non-lymphoid tissues, an area previously not well understood.

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 clinical features, diagnosis, and treatment options for alopecia areata of the beard and reports no new clinical results.

In this study, researchers found that alopecia areata patients show a significant reduction in suppressive regulatory T-cells and an increase in inflammatory T-cell populations, suggesting an immunological imbalance contributing to the disease.

Lichen Planus is a less common condition affecting skin and mucous membranes, with various types and associated risk factors, challenging to diagnose, significantly impacts life quality, and may have a risk of cancerous changes in oral lesions.
