This study suggests that Merkel cell polyomavirus T antigen-positive cells resembling Merkel cell carcinoma may originate from epithelial cells in human hair follicles, potentially informing future transgenic mouse models for this cancer.

This study found that incorporating collagenase type I into a noncultured hair follicle cell suspension technique improved cell yield and enhanced repigmentation in patients with stable vitiligo compared to dermabrasion alone.

This study found poor agreement among dermatopathologists in identifying and grading fibrosis in traction alopecia, suggesting the need for better diagnostic methods for early fibrosis detection.

This study suggests obstructive sleep apnea may increase the risk of male-pattern baldness in men with a family history of hair loss, and links low serum transferrin saturation levels to both conditions.

In this study, transverse sectioning of scalp biopsy samples showed higher diagnostic accuracy than vertical sectioning for noncicatricial alopecia, although both techniques are important for accurate diagnosis.

This study found that vitamin C deficiency in SMP-30/GNL-KO mice affected gene expression related to hair growth and cell growth, resulting in delayed hair growth compared to those with adequate vitamin C.

This study found that the transcription factor CAP1 negatively regulates KRT83 expression in Tan sheep, possibly influencing their curly hair phenotype.

In this study, BeauTop treatment significantly increased hair growth in people with androgenetic alopecia compared to placebo, showing effectiveness without adverse reactions.

This article reviews the promising ease of drug administration via transdermal and other topical routes, highlighting their potential for high patient compliance and reduced side effects but provides no new clinical results.

In this study, topical phenylephrine significantly reduced hair shedding and increased the force needed to pluck hair in women undergoing cosmetic procedures, suggesting its potential utility for traction alopecia.

This report presents a 6-year-old girl with Turner syndrome, suggesting a possible association between Turner syndrome, psoriasis, alopecia areata, and trachyonychia.

This letter to the editor presents two new cases of traumatic panniculitis with localized hypertrichosis and provides clinical considerations, but it does not report experimental findings.

This study reports that using LED polarized magnification in hair transplant recipient sites can reduce eye strain and improve ease of site creation, but offers no graft placement advantage over traditional methods.

This study suggests that keratinocytes in skin and mucous membranes might be involved in prion disease transmission due to their expression of PrPc, potentially serving as an entry point for prions.

The researchers reported that applying proteolytic enzymes to mice skin negatively affected hair follicles, leading to degeneration and potential impairment of stem cells from the bulge area.

The method effectively maps lead and zinc in hair, aiding understanding of heavy metal exposure risks.

This study found that human induced pluripotent stem cells differentiated precisely to express certain markers during a specific window could enable successful hair follicle generation when transplanted.

This study explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.

This review highlights recent advances in the design of nanocarrier systems for transdermal drug delivery, detailing their potential to improve treatment precision for dermatologic conditions despite challenges like formulation stability and scalability.

This review explores how molecular profiling in atopic dermatitis has led to new therapeutic developments, detailing approved and potential treatments, and discusses similar advances in alopecia areata; it reports no new results.

This study investigated transcription factors in human trophectoderm cells during development, finding that GATA2 and GATA3 are essential for transforming stem cells into induced trophoblast stem cells, which display characteristics similar to placental progenitor cells, offering new methods for modeling placental-associated diseases.

This study found that the BP-3 extract from Boesenbergia rotunda, rich in panduratin A, demonstrated strong anti-adipogenesis and lipolysis effects on preadipocyte cells at non-toxic concentrations, and when formulated into a serum reduced thigh circumference and improved skin firmness in a human trial.

This study found that adapalene-loaded microemulsions significantly enhanced the drug's penetration through guinea pig skin compared to an aqueous suspension, with factors like surfactant ratios and the water-oil phase balance affecting the transfollicular drug delivery efficiency.

This study found that transplanting adipose tissue into the rat dorsum supported long-term skin expansion by enhancing thickness, vascularization, and cell proliferation, with adipose-derived cells actively contributing to skin regeneration and growth factor expression.

This review discusses the use of zinc supplementation in dermatology for various skin conditions and reports no new clinical results, providing references for its application.

This study found that patients with alopecia areata had higher serum levels of miRNA-205 and TGF-β1, but lower levels of lncRNA HOTAIR, suggesting a potential target for therapy.

This study reports that psoriasis prevalence among transgender individuals is similar to that in the general population, with possible links to gender-affirming hormone therapy needing more research.

This study revealed that chronic restraint stress in mice led to significant alterations in metabolic pathways and gene expression associated with hair growth inhibition, using metabolomics and transcriptomics analyses.

This article discusses the potential of novel microneedle transdermal systems for enhanced drug and vaccine delivery through the skin, but reports no clinical results and emphasizes ongoing trials.
