Higher levels of small, dense LDL cholesterol are linked to a greater risk of heart attack in young adults.

This study found that the ID2 gene was highly expressed in bulge-derived keratinocytes when exposed to contact sensitizers and may serve as a marker to distinguish sensitizers from irritants during in vitro testing.

This study suggests that Sonic hedgehog from hair follicles may support the proliferation of dentate neural stem cells in mice through transport by platelets during the perinatal period.

This study found that the absence of unliganded vitamin D receptor significantly impairs cWnt and hedgehog signaling pathways necessary for hair cycle initiation in VDR-null mice.

In this study, D6D knockout mice showed severe deficiency in AA and DHA, leading to unexpected effects on skin health, fertility, and immune cell development.

This review discusses the antimicrobial and protective effects of hesperidin and hesperetin against various toxicities, with potential mechanisms explored, but it reports no new research findings.

This case report details a rare instance of granulomatosis disciformis chronica et progressiva affecting both skin and lymph node tissue in a 31-year-old man.

This study found that KLF4 expression in mouse hair follicle stem cells is important for effective cutaneous wound healing, with its knockdown leading to reduced stem cell populations and delayed healing.

This study found that disrupting Sdf1-Cxcr4 signaling promoted tissue regeneration in wild-type mice, hinting at potential strategies to induce such regeneration in mammals.

This study identified lymphatic vessels as crucial components of the hair follicle stem cell niche, coordinating connections and contributing to hair follicle regeneration in mice.

This study found that mechanical disruption of the desmosomal cadherin Dsg3 in hair follicle stem cells activates them from quiescence, highlighting its role as a key regulator of stem cell quiescence and epithelial niche integrity.

This review discusses the physiological roles of the epidermal differentiation complex and its potential involvement in psoriasis, but it reports no new experimental findings.

This report describes two South Australian Poll Hereford calves with a syndrome of congenital dyserythropoietic anaemia, dyskeratosis, and progressive alopecia, observing specific blood and bone marrow abnormalities.

This study found that bulge cells marked by CD200+ in human hair follicles show high colony-forming efficiency, suggesting successful enrichment of keratinocyte stem cells.

This review explores the efficacy and safety of treatments for dissecting cellulitis of the scalp, revealing a predominance of case reports and series, and concludes that randomized controlled trials are needed for better evidence-based therapies.

This case study reports an unusual presentation of primary cutaneous diffuse large B-cell lymphoma–leg type occurring on the upper lip of an 81-year-old woman, highlighting the need for timely recognition of atypical manifestations.

This report discusses the characteristics of circle hairs, a type of body hair growth disorder, and emphasizes the value of trichoscopy for diagnosis.

Hair transplantation can lead to rare scalp complications, requiring careful follow-up and treatment.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

This study identified a distinct CD49fhigh mesenchymal stem cell subpopulation in the dermis that supports hair follicle development and maintenance via Notch signaling activation.

A 4kb fragment of the desmocollin 3 promoter targets gene expression to specific skin and hair follicle areas.

This study found that dermal white adipose tissue surrounding human hair follicles enhances proliferation, pigmentation, and hair shaft elongation in an ex vivo setting.

In this study, gamma/delta T cells were observed in skin after allergic or irritant reactions to heavy metal salts, suggesting a role in skin defense against these metals.

This study used single-cell and spatial transcriptomic profiling to identify specific molecular markers in human follicular dermal papilla cells, enhancing understanding of their role in hair follicle development.

This study developed a new measurement procedure using isotope dilution-liquid chromatography-tandem mass spectrometry for accurate quantification of DHEAS in human serum or plasma, demonstrating high selectivity, sensitivity, and low measurement uncertainty, making it suitable for routine standardization and clinical evaluation.

Wnt signaling affects the development and growth of Langerhans cells in mice.

This study suggests that D2O increases hair length in nude mice by extending the hair cycle duration, particularly the hair-existing phase, which is associated with increased mast cell density.

This study found that Dermal Fibroblast Progenitors have repressed chromatin profiles which hinder their ability to reform skin in allograft assays despite their differentiation potential.

This case report identifies an association between trichothiodystrophy and a urologic malformation with primary hypercalciuria, adding to the spectrum of TTD-related abnormalities.

This study indicates that CD4 protein may have a functional role in basal cell-like keratinocytes through TCR/CD3-independent signaling, affecting their proliferation, differentiation, and migration.
