In this study, researchers found that knockdown of ABCA5 in primary human hair follicle keratinocytes disrupted cholesterol homeostasis and transportation, suggesting its potential role in hair growth disorders by affecting intracellular cholesterol compartmentalization and LXR-mediated transcriptional activity.

This study identified histologic lesions and a defect in adhesion molecules causing hair loss in mice with the bal mutation, linked to a mutation in the desmoglein 3 gene.

This study presents a case of idiopathic alopecia mucinosa achieving complete remission with minocycline treatment and reviews the existing literature on the condition.

This dissertation reports that horizontal basal cells in the olfactory epithelium undergo symmetric divisions balanced by population asymmetry, which supports their renewal and differentiation during tissue homeostasis and regeneration.

This study found that inducing Atoh1 expression in transgenic mice is sufficient to generate new Merkel cells in the epidermis, with variations by skin location, developmental age, and hair cycle stage.

This study observed that transgenic mice expressing keratin K10 under bovine K6beta control developed severe oral abnormalities, suggesting keratin composition changes can affect the physiology of epithelial cells, especially in the oral mucosa.

This study found that the NuMA protein's microtubule-binding domain is essential for proper spindle orientation and differentiation in keratinocytes, affecting skin and hair development in mice.

This study suggests that analyzing the composition and modifications of hair proteins may provide new biomarkers for assessing hair health, diseases, and aging.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study shows that alpha 6 + /MHCI - cells have gene expression profiles similar to hair follicle stem cells, suggesting they may be enriched for stem cells.

This study found that MAP-2 is intensely expressed in the companion layer of the hair follicle, suggesting its potential importance to follicle integrity and possible involvement in some types of alopecia.

In this study, injecting Nε-(carboxymethyl) lysine into skin tissue weakened hair shaft and follicle formation, likely by inhibiting cell proliferation and migration needed for hair follicle morphogenesis.

This study found that mice lacking the 1αOHase enzyme, which is responsible for producing a key vitamin D metabolite, showed impaired epidermal differentiation and delayed recovery of skin barrier function after disruption.

This study found that persistent activation of Wnt signaling in mouse models leads to cyst formation in hair follicles, resembling acne, and that these cysts can be partially reduced by certain acne treatments.

This case report describes a 10-year-old girl with monilethrix, detailing hereditary autosomal dominant traits and distinctive nodular hair shaft abnormalities observed in her family through clinical examination and microscopic analysis.

The authors present a case of punctate follicular porokeratosis, suggesting it as a distinct clinical entity distinguished by keratotic lesions originating specifically from hair follicles.

This study found that aminomethylpyrazole compound 10l inhibited hair growth in a mouse model and showed a low risk for photo-irritation, though it was slightly less effective than eflornithine.

This study found that myristoleic acid promotes dermal papilla cell proliferation and anagen signaling through autophagy, cell cycle progression, and activation of the Wnt/β-catenin and ERK pathways.

In this study, mannosylerythritol lipids from soybean oil notably increased fibroblast and papilla cell viability, suggesting potential as a hair growth agent.

This study found that keratin 15 expressing cells from the hair follicle contribute to the development and long-term persistence of cutaneous papillomas in transgenic mice, with a subset showing the Ha-ras mutation.

This review discusses hair abnormalities in various epidermolysis bullosa subtypes and reports no new clinical findings.

This study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.

In this study, researchers observed that alopecia areata patients showed higher Th1 and Th2 responses against specific melanogenesis-related protein epitopes, suggesting a role in disease activity and potential targets for diagnostics and therapies.

This study discusses calcinosis cutis and alopecia totalis, highlighting the need for thyroid disease screening in children with alopecia areata, especially those with a history of Down syndrome or signs of potential thyroid dysfunction.

In this study, the antibody A3 identified quiescent post-progenitor epithelial and mesenchymal cells in developing rat hair follicles, suggesting it may help track the differentiation of these cells.

This study reported that canine dermal papilla cells showed a distinct growth pattern and strong collagen IV and laminin staining compared to dermal fibroblasts.

This study observed that albino rats, despite not producing melanin, have melanocytes localized in specific skin areas of their hair matrix, suggesting that gene expression analysis of their skin should consider regional differences in melanocyte presence.

This study suggests that interfollicular epidermal keratinocytes with stem-like features may serve as an alternative to follicular keratinocytes for hair regeneration by supporting hair follicle morphogenesis in vivo.

This study suggests that the phenotype of melasma in women is influenced by structural and cellular changes across the epidermal-melanin unit, not just melanocyte hypertrophy, highlighting potential roles for dermal damage repair and fibroblast senescence.
