This review evaluates dihydrotestosterone's role in androgenic alopecia and proposes a model suggesting that chronic scalp tension and inflammation contribute to hair follicle miniaturization, identifying fibrosis, calcification, and tension as treatment targets.

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

This review discusses the structure and regenerative potential of hair follicles, highlighting their role in wound healing, stem cell populations, and keratin-based biomaterials, but it reports no new clinical results.

This study found that androgen/androgen receptor signaling accelerates premature senescence in dermal papilla cells, highlighting a potential target for treating androgenetic alopecia.

This review examines the debated link between iron deficiency and nonscarring scalp alopecia in women, offering no new clinical results but emphasizing the need for further research and well-designed trials.

This article discusses hair loss in postmenopausal women as often being multifactorial, reviewing various conditions affecting this group, but reports no new research findings.

This review proposes a classification system for childhood hair loss based on clinical appearance, age of onset, and associated symptoms, but reports no new clinical results.

This study found enhanced remyelination in the corpus callosum of late pregnant rats compared to virgin and postpartum rats, suggesting a pregnancy-associated promyelinating effect mediated, in part, by the GABA A receptor system.

This article is a discussion piece that examines the clinical symptoms of hyperandrogenic women with COVID-19, without reporting new research findings.

The study suggests that a 3D culture system using the RAD16-I peptide scaffold can help restore the original phenotype of hair follicle dermal papilla cells and support their osteogenic and adipogenic differentiation.

In this study, Treg depletion impaired skin wound healing in mice, potentially by altering the cytokine environment and expanding certain T-cell populations, disrupting the normal healing process.

This study found that in squamous cell carcinomas, the inhibition of the tumor-suppressor function of TAp73β by ΔNp63α occurs through promoter squelching, not direct protein interaction.

This review discusses the developmental regulation of wound healing mechanisms in mammals, focusing on the role of the Wnt and TGF‐β signaling pathways, and reports no new clinical findings.

This article reviews the structure and regulation of the ITGB6 gene and discusses its role in integrin αvβ6 expression, with no new experimental results reported.

This review discusses the function and pathology of hair follicles and highlights the potential of using dogs as a model to study human hair and stem cell disorders, but presents no new experimental results.

This review introduces an integrated view of hair follicle behavior, highlighting a Yin Yang model of regulation and suggesting glycans as key elements in hair follicle growth control, without reporting new clinical findings.

In this study, a low-methionine diet significantly improved the health and physical traits of cystathionine β-synthase-deficient mice, contrasting with negative effects on mice with partial deficiency.

This study identified that rose, thyme geraniol, palmarosa, and tolu balsam essential oils activate TRPV1, with citronellol and geraniol as newly recognized agonists.

This study found that Sp6 overproduction in ameloblast-lineage cells increased cell proliferation and ameloblastin expression, suggesting that Sp6 promotes amelogenesis by inhibiting follistatin gene expression.

This review classifies engineered nanomaterials by composition and application in biomedicine, highlighting diverse uses like regenerative medicine and potential occupational side effects, but reports no new clinical results.

This source reports that thymosin beta 4 accelerated dermal wound repair in phase 2 clinical trials for pressure ulcers, stasis ulcers, and epidermolysis bullosa wounds and was well tolerated.

This study found a higher prevalence of metabolic syndrome in patients with lichen planus, especially those with mucosal involvement, which is associated with increased cardiovascular and diabetes risk.

In this study, inactivating the TAF4 subunit of transcription factor TFIID in mouse epidermis disrupted gene expression linked to skin and hair function, and increased tumor risk.

In this study using genetic mouse models, researchers discovered that senescent melanocytes in nevi secrete osteopontin, which activates hair stem cells, enhancing hair growth; this process is mirrored in human hairy nevi, suggesting a potential therapeutic target for regenerative disorders.

This review examined dermatologic symptoms associated with COVID-19 in 2,560 patients, with chilblains/pernio-like lesions being the most common, suggesting these symptoms may aid in early identification of cases.

This study found that in psoriasis patients, the K17 protein probably functions as an autoantigen, with the HLA-Cw*06:02 risk genotype strongly linked to the T cell response size.

This study found that a cocktail of three proteins from embryonic skin can enable adult fibroblasts to regenerate hair follicles by altering gene expression and activating regenerative signaling pathways.

In this study, researchers found that a polyphenolic extract from Annurca apples, high in procyanidin B2, increased hair growth, density, and keratin content in healthy subjects after 2 months of use, and stimulated keratin biosynthesis in vitro.

This study found that Undariopsis peterseniana extract may promote hair growth by activating specific cellular pathways, suggesting potential for treating alopecia.

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.
