This study identified dual epithelial and mesenchymal traits in dermal sheath cells during wound repair, suggesting they could be targeted to enhance healing.

This study developed and analyzed a mathematical model for alopecia areata involving interactions among immune cells and cytokines, establishing conditions under which hairless patches can become stable and pervasive, particularly with certain biological rate levels and chemotactic sensitivities.

This study found that patients with alopecia areata and their healthy family members had elevated levels of Th1- and Th17-related cytokines, suggesting a genetic link in cytokine dysregulation.

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 review discusses recent advances in understanding alopecia areata's disease mechanisms and highlights JAK molecules as promising therapeutic targets, but reports no new clinical results; controlled trials are needed.

This study found that forming inclusion complexes of DPCP with HPβCD using the 3D ground mixture method enhances its anti-inflammatory activity at lower doses compared to complexes with β-CD.

This review examines the pathophysiological mechanisms and emerging targeted treatments for alopecia areata, particularly highlighting the efficacy of oral JAK inhibitors over other less effective alternatives.

This case study reports the first known instance of successful rapid hair regrowth in a psoriasis patient with alopecia universalis after starting deucravacitinib, suggesting potential for TYK2 inhibitors in managing alopecia areata.

In this open-label trial, Tofacitinib was well tolerated and improved IFN and cytokine scores, as well as overall skin pathology, in individuals with Down syndrome and immune skin conditions.

This case study reports the first extensively interpreted instance of dystrophic telogen effluvium potentially linked to pegylated interferon and ribavirin therapy for chronic hepatitis C, characterized through clinical and trichogram analysis.

This review discusses current and emerging treatments for discoid lupus erythematosus, suggesting that new biologic and small-molecule therapies may improve disease control when combined with traditional management.

In this study, researchers demonstrated that CD4 T cells from skin-draining lymph nodes in mice with alopecia areata can transfer the disease to recipient mice, revealing a critical role for CD4 T cells in disease development and suggesting potential therapeutic targets.

This study examines the genetic underpinnings of chronic dermatological conditions like acne, androgenetic alopecia, and alopecia areata, concluding that a deep understanding of these mechanisms can advance patient-specific treatments and inform cosmetic practices related to skin and hair health.

Reducing CD8+ T cell growth can stabilize alopecia areata.

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.

This source reports that for treating keloids and hypertrophic scars, combination pharmacotherapy targeting multiple sites is generally more effective than using a single drug, though outcomes of individual therapies vary and the development of satisfying treatments is ongoing.

This study found that patients with alopecia areata had significantly higher levels of circulating DNA for certain cytokines compared to healthy controls, suggesting that increased circulating DNA may be linked to hair follicle damage in these patients.

This study found that subcutaneous injection of a CXCL12 neutralizing antibody significantly promoted hair growth in androgenic alopecia and inhibited hair loss in alopecia areata in mouse models, suggesting its potential as a promising treatment for hair loss.

This study identified shared gene expression changes and immune cell infiltration patterns that may contribute to hair loss in alopecia areata and cutaneous lupus erythematosus, but also highlighted factors that might preserve hair in psoriasis patients.

In this study, researchers found that the loss of SETDB1 in epidermal keratinocytes led to altered chromatin states, increased ERV expression, and activation of immune responses, while inhibiting these effects with certain antiviral drugs reduced skin inflammation and hair loss in a mouse model.

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 study found that ILC1-like cells can induce alopecia areata symptoms in both ex vivo human hair follicles and in vivo mouse models, challenging the view that alopecia areata is solely CD8+ T cell-driven.

In this study, Wang et al. (2022) found that in patients with cutaneous lupus erythematosus, chronic lesions contained more senescent progenitor cells, marked by p16 and p21, than subacute lesions, suggesting a link between disease chronicity and cellular senescence.

This review outlines the proposed theories behind the development of alopecia areata, emphasizing the autoimmune process involving lost immune privilege in hair follicles, and stresses the need to pinpoint specific pathogenic mechanisms for potential treatments.

This review discusses potential biomarkers for alopecia and their significance, and while it highlights areas for future research, it reports no new clinical results.

Lichen Planopilaris causes irreversible hair loss due to immune attacks on hair stem cells, but modulating PPAR-γ might help treat it.

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.

This study reported that CCT oligodeoxynucleotide induced patchy hair loss in male mice with specific genetic traits, suggesting gender and genetic preferences in immune response.

A man's skin cancer improved and some of his hair grew back after treatment with a special light therapy and a medication.

Researchers developed a new way to measure gene activity in single hair follicles and found that a specific gene's activity changes with different amounts and times of treatment.
