This study found that DNA is present at low levels in human hair shafts, with higher amounts near the root, and that its levels decrease after surfactant washing and colorant treatments.

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 study found that age is the most significant risk factor for hemorrhagic cystitis after hematopoietic stem-cell transplantation, with additional risk factors including cyclophosphamide-based prophylaxis and, among male recipients, prostatic hyperplasia.

This report describes three cases of hypertrichosis lanuginosa acquisita occurring after cytotoxic chemotherapy for cancer, suggesting a possible relationship which is discussed alongside a review of existing literature.

This meta-analysis found an increased prevalence of hypothyroidism in patients with lichen planopilaris compared to controls, though the exact relationship between the two conditions remains unclear.

This review discusses the current understanding of frontal fibrosing alopecia's pathogenesis, highlighting genetic susceptibility, immune response involvement, and possible links to steroid hormones, but reports no new clinical results.

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, researchers found that cytokine dysregulation linked to genetic background is present in both patients and healthy but genetically related individuals in two autoimmune skin diseases, Pemphigus vulgaris and Alopecia areata, suggesting that protective immune mechanisms may prevent disease manifestation in predisposed individuals.

This study highlights the genetic complexities in alopecia areata, emphasizing the role of microRNAs and their association with other immune-related diseases, which could inform targeted treatment strategies.

This chapter reviews trichoscopic-pathologic correlations in Frontal Fibrosing Alopecia and reports no new clinical results; the authors discuss genetics, clinical patterns, and unusual variants associated with this condition.

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 among patients with Down syndrome, those with alopecia areata may have increased antiperoxidase antibodies, possibly linked to hypothyroidism.

Alopecia areata is an autoimmune disease with genetic links, treatable with certain medications, and can affect mental health.

This article reviews potential causes of frontal fibrosing alopecia but does not provide new clinical findings.

This study highlights lichen planopilaris as a form of scarring hair loss with symptoms like shedding and itching, and notes successful treatment options such as topical and oral antiinflammatory medications to preserve hair follicles by early intervention.

Certain immune system genes are linked to a higher risk of psoriasis and psoriatic arthritis, while others may offer protection.

This study suggests that a specific subpopulation of umbilical cord-derived mesenchymal stem cells, CMD, may enhance wound healing and tissue quality in chronic skin ulcers, with promising results in both murine and equine models.

In this study, researchers conducted a large genome-wide association meta-analysis and found 30 significant genetic loci linked to the risk of dermatophytosis, shedding light on the roles of keratin biology, skin barrier defects, immune dysfunction, and obesity in the disease.

This review highlights advances in understanding alopecia areata as a systemic disease involving genetic, immune, and environmental factors, noting new treatments like Janus kinase inhibitors but acknowledging challenges in long-term safety and accessibility.

This study found that eyebrow follicles, as opposed to buccal swabs or nails, are the most reliable tissue for post-HSCT germline genetic testing due to lower donor DNA contamination.

In this study of women with breast cancer undergoing chemotherapy and scalp cooling, 12% experienced incomplete hair regrowth at 6 months, with tamoxifen therapy identified as a significant risk factor for persistent chemotherapy-induced alopecia.

This study found that both desmoglein-specific and non-desmoglein autoantibodies may play active roles in Pemphigus vulgaris pathogenesis, with HLA genetics influencing autoimmune specificity.

Genetic factors affecting skin health and body weight may increase the risk of dermatophytosis.

In this study, researchers identified genetic factors associated with frontal fibrosing alopecia, noting a protective effect of a specific CYP1B1 gene variant, which may offer insights into the disease's pathogenesis and future risk mitigation strategies.

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.

This study found that in atrophic acne scars, inflammation infiltrates the pilosebaceous unit over time, affecting resident stem cells and hindering the normal regeneration of the epidermis and adnexal structures, leading to scarring.

Frontal fibrosing alopecia is a scarring hair loss condition mainly affecting postmenopausal women, with unclear causes.

This study reports that while primary treatment for uveal melanoma has a very high success rate, treating distant metastases, particularly in the liver, remains challenging. Tebentafusp, dependent on HLA-A expression, is the first drug to extend patient survival.

This case report highlights how chronic bacterial folliculitis may contribute to persistent inflammation in lichen simplex chronicus and emphasizes the value of DIF and IHC in diagnosing obscure cases.

This review summarizes recent genetic research on hidradenitis suppurativa, highlighting potential therapeutic targets and genetic mutations, but reports no new clinical findings.
