This study found that elevated STAT5 levels are linked to improved hair-inducing capabilities in human dermal papilla cells, and reducing STAT5 impairs hair follicle induction.

This study found that treating human dermal fibroblast cells with ginsenoside Rd increased the expression of mRNA associated with the dermal-epidermal junction, suggesting potential as an anti-aging cosmetic ingredient.

This study found that TGFbeta is a key pathway causing age-related loss of dermal fat's antimicrobial function, suggesting that targeting TGFBR might help restore skin defense against infections in older age.

This study found that terminally differentiated effector memory Vδ1T-cells and their cytotoxic activation markers were elevated in alopecia areata patients, suggesting these cells may contribute to its early pathogenesis.

The researchers reported that nicotinic acid normalized excessive sebaceous lipogenesis without affecting basal lipogenesis and suggested potential anti-acne benefits.

This study reports that 71% of patients treated with the gamma-secretase inhibitor PF-03084014 for desmoid tumors experienced dermatologic side effects, such as follicular lesions and pruritic eruptions, which were managed with topical or systemic treatments.

In this study, Mpzl3-/- mice developed severe seborrhea-like dermatitis with skin inflammation, indicating MPZL3's role in the skin condition's development, independent of adaptive immunity.

Different cells affect hair follicle blood vessels, endothelial cells react differently to inflammation and oxidized fats, and prasugrel better protects heart vessels during a procedure than clopidogrel.

Prasugrel is better than clopidogrel at preventing heart damage and improving blood flow in small heart vessels during heart artery procedures.

This study found that the absence of Hes1 in hair follicles delays secondary hair germ activation and shortens the anagen phase, impacting HFSC self-renewal and long-term hair regeneration.

This study developed molecular signatures for dermal papilla cells and their niche, uncovering novel signaling regulators and genes linked to hair disorders, which may inform future hair development research.

This review examines current knowledge on human epithelial hair follicle stem cells, their markers, and outlines challenges in translating findings from murine studies to human research, but does not report new experimental results.

This article discusses the potential genetic basis of central centrifugal cicatricial alopecia in women of African ancestry but does not provide new research results.

In this study, researchers found that TCDD exposure accelerated differentiation and altered gene expression in human epidermal cells, indicating the epidermal barrier as a target of TCDD-activated AHR.

This study proposes the miR-22-5p-LEF1 axis as a novel pathway that may regulate hair follicle stem cell proliferation.

This study identified 16 novel high sulfur KAP genes and two KAP pseudogenes on chromosome 21q23, showing expression in a specific region of the hair fiber cuticle.

This study reports that Lef1 plays a crucial role in promoting bulge stem cell differentiation towards hair fate by activating β-catenin and downstream signaling pathways during hair follicle development.

This study proposes a new method to selectively isolate keratin-associated proteins and keratin from human hair, suggesting that KAPs may support keratin fibers in hair structure.

This study found that skin microbiota, particularly in wild-type mice, promotes wound-induced hair follicle neogenesis and wound healing, highlighting the potential downsides of routine antibiotic use on skin regeneration.

This article reviews innovations in hair cosmetics, focusing on esthetic procedures and products in the Indian market, and reports no new experimental findings.

This study identified two types of calcium in human scalp hair, with one type highly variable between individuals, potentially impacting the analysis of environmental and medical factors related to hair calcium.

This study identified overexpression of certain immune-related genes and underexpression of genes in specific signaling pathways in premature androgenetic alopecia, suggesting potential new therapeutic targets.

In this study, overexpression of Wnt5a in mice was associated with the elongation of the telogen stage and inhibition of hair growth initiation, suggesting Wnt5a's role in maintaining hair follicle quiescence.

This study found that inhibiting AP1 transcription factor activity in the suprabasal epidermis of mice alters keratinocyte gene expression, reducing barrier integrity and mimicking human keratoderma.

This study found that platelet-rich plasma may influence the proliferation of human hair dermal papilla cells by affecting gene expression related to the cell cycle.

This study found that higher concentrations of copper (II) ions in human hair increase protein oxidative modification, contributing to hair damage regardless of UV exposure and pigmentation level.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

This study found that hair proteome profiling and genetically variant peptide identification in hairs remained effective after an explosive blast, indicating potential for forensic human identification despite damage.

This study found that integrin-linked kinase is crucial for various epidermal functions, including differentiation and barrier formation, and also plays a previously unreported role in melanocyte development and function.

In this study, researchers found that androgenetic alopecia is associated with increased gene expression related to inflammation, stress, and fibrosis, particularly affecting the hair follicle stem cells and showing similarities to diseases like psoriasis.
