This article reviews the genetic and potential environmental factors in alopecia areata's pathogenesis and suggests a polygenic model but reports no new clinical findings.

This study found that elevated serum cortisol levels and other immunological changes are significantly involved in the active phases of psoriasis eruptions.

This study found significantly higher levels of the protein ULBP3 in patients with alopecia areata incognita compared to other hair loss conditions and healthy controls, suggesting ULBP3's potential as a diagnostic marker for AAI.

This symposium discussed why regenerative capacity varies among species and diminishes with age, exploring how these insights could inform regenerative medicine approaches, without presenting new experimental results.

This article discusses a case of patchy alopecia areata that spares greying hairs but reports no new findings; it refers to existing literature for context.

This review discusses the evolution of alopecia areata treatments towards more targeted therapies and reports no new clinical results, emphasizing cooperation between clinicians and scientists in understanding the disease's pathophysiology.

This article reviews how biomaterials and stem cells could advance regenerative medicine but does not report new results, emphasizing the potential of combining novel biomaterials with stem cells for effective therapies.

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.

This review discusses recent advances in the understanding of alopecia areata, focusing on immunity and genetics, and presents potential targets for therapy without reporting new clinical results.

This review discusses the mechanisms of zinc transport, its role in human health, and the effects of zinc imbalance, without reporting new results.

This review explores the potential role of caveolin-1 in cicatricial alopecia, particularly frontal fibrosing alopecia, and discusses possibilities for targeted therapies without providing new research results.

In this case study, the progression of alopecia universalis in a Japanese man was linked to the involvement of Th1 and Th17 cells, suggesting an autoimmune mechanism.

This report describes a case of alopecia areata returning as AA universalis in a 63-year-old woman after receiving the SARS-CoV-2 vaccine, following a 32-year remission.

This review suggests that the gut microbiome and metabolome may play a significant role in alopecia areata and emphasizes the potential of targeting these factors for improved prevention, diagnosis, and treatment strategies for this skin condition.

This review discusses the impact of immune-modifying therapies on COVID-19 vaccine responses, noting that a complete vaccine course can improve initially inadequate humoral responses among treated individuals compared to a single dose.

This review discusses the role of dermal macrophages in stress-induced hair regeneration and reports no new clinical findings, highlighting the need for further research into macrophage dynamics for potential hair loss therapies.

This article reviews the autoimmune mechanism and potential environmental triggers of alopecia areata, focusing on cytokines, but does not provide new research findings.

This genome-wide association study identified several genetic markers, including specific SNPs and HLA genotypes, associated with alopecia areata susceptibility in the Taiwanese population, highlighting key pathways involved in immune response and offering insights into the genetic origins of this autoimmune condition.

In this study, the researchers synthesized copper-doped mesoporous silica nanoparticles and observed that they enhance tumor microenvironment regulation and, when paired with disulfiram, effectively kill cancer cells while also showing synergistic anti-tumor effects with immune checkpoint inhibitors.

This study reports that a novel gain-of-function mutation in TMEM173, combined with polymorphisms in TMEM173 and IFIH1, results in a distinct clinical phenotype with features of SAVI, including alopecia and photosensitivity.

This narrative review proposes the concept of "repigmentation competence" for vitiligo lesions, suggesting that therapy responses are influenced by lesion-specific biological factors related to immune, regenerative, regulatory, and microenvironmental processes, and highlights the emerging role of combination therapies targeting these pathways.

This study found that individualized homeopathic medicine can significantly improve outcomes in patients with alopecia areata, including complete hair regrowth and reduced SALT scores within 5 to 12 months, without relapse, and shows promise for alopecia universalis through targeted miasmatic and constitutional remedies.

Hair graying may help prevent cancer by protecting stem cells.

This review highlights recent advancements in understanding and treating alopecia, emphasizing genetic and immune factors involved in different forms, and discusses emerging therapies such as gene-editing and exosome-based treatments, though achieving complete hair regrowth remains a challenge.

In this study, researchers found that a cold atmospheric plasma-activated hydrogel containing interleukin-2 significantly enhanced hair regeneration in a depilated mouse model, promoting larger hair follicles and faster hair growth phase transition, suggesting it as a potential treatment for hair loss.

This study reviewed evidence on the role of specific genes (FKBP12, SAMAHD1, TRF2, CD155, and GATA3) in predicting how breast cancer patients might respond to adjuvant chemotherapy, aiming to monitor these markers in blood or tissue samples.

This study observed that dandruff-affected scalp skin has increased T-cell infiltration in the epidermis and a reduction in the hair follicle's physiological immune privilege, particularly in the suprabulbar outer root sheath area, indicating a distinct immune microenvironment compared to healthy scalp.

In this report, the authors describe a case where a child developed alopecia areata after receiving the fifth dose of a rabies vaccine, suggesting that the vaccine may predispose to this autoimmune hair loss by affecting immune regulation.

This study found increased infiltration of specific immune cells, such as γδ T cells and CD8+ T cells, in the bald scalp of male androgenetic alopecia patients, and identified four key immune-related genes potentially involved in hair loss development through interferon-γ signaling pathways.

This review summarizes recent genetic findings in alopecia areata research and their implications for developing new treatments, without reporting new clinical results.
