This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

In this study, researchers found that disrupting the PRL gene in mice led to earlier hair molting, especially in females, suggesting that PRL inhibits murine hair cycle events.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This review assesses the benefits and limitations of various supramolecular hydrogels, including polymeric and peptide-based types, for wound healing, but reports no new clinical results.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

This study introduced a novel in vitro assay for tracking melanosome transfer between melanocytes and keratinocytes, facilitating the quantification of melanin transfer and supporting the role of filopodia as a conduit.

This study found that overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

This study found that overexpression of Hoxc13 in GC13 mouse models affects hair follicle differentiation by interacting with medulla-specific genes, particularly Foxq1, suggesting a regulatory pathway for medulla differentiation.

This study reports that overexpressing the BMP antagonist noggin in mice inhibits eyelid opening by reducing apoptosis and delaying cell differentiation in the eyelid epithelium.

This article discusses the foundational concepts of nanotechnology and its contributions to dermatology and medicine, but does not present new research findings.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.

This review discusses the complex causes and treatment challenges of chronic inflammatory skin diseases, emphasizing the need for biomarkers to predict treatment responses; it reports no new clinical results.

This study found that a new topical nitric oxide gel significantly accelerated burn wound healing in mice by enhancing re-epithelialization, hair follicle regeneration, collagen deposition, and angiogenesis compared to controls.

This article reviews major types of genetic hair shaft defects and associated syndromes, emphasizing understanding histologic features and diagnostic methods, but reports no new clinical findings.

This paper discusses the variability in COVID-19 susceptibility and severity, emphasizing factors like biological differences and suggesting potential precision medicine approaches, but it reports no new clinical results.

This study found that dual inhibition of BACE1 and BACE2 in mice affects melanosome maturation and causes dose-dependent hair depigmentation without altering retinal morphology.

Graft-versus-host disease is a complication where donor immune cells attack the recipient's body, often affecting the skin, liver, and gastrointestinal tract.

This study found that the JMJD3/NF-κB-Notch1 pathway plays a crucial role in regulating keratinocyte migration and skin wound healing, with Notch1 affecting key genes involved in cell migration.

This study found that in scarring alopecia, stem cells are differentially localized, suggesting that both inner and outer root sheath stem cells, rather than just follicular bulge stem cells, are involved.

This article discusses the etiology, clinical features, diagnosis, histopathology, and treatment of alopecia areata but reports no new clinical findings; it emphasizes the palliative nature of current treatments.

This study found that mouse FLRG protein, a secreted glycoprotein, is expressed in certain tissues and plays a role distinct from follistatin during wound healing, suggesting different functions in vivo.

This study revealed that during fetal development, MITF and Mart-1 expressing melanocytes progress from the dermis to the epidermis and hair follicles, with MITF possibly marking follicular stem cells.

This study found that most pathogenic HR mutants associated with atrichia with papular lesions had abolished corepressor activity due to defective interactions with histone deacetylases.

This study observed that nuclear β-catenin expression in non-small-cell lung carcinomas correlates with increased proliferation and loss of key cell-cycle checkpoints, suggesting an oncogenic advantage.

This review discusses current and potential treatments for alopecia areata, focusing on immunosuppressive and immunomodulatory approaches, but provides no new clinical results.

In this study, spiny mice showed superior cardiac recovery after myocardial infarction compared to other mouse strains, with enhanced myocardial preservation and functional stabilization.

This study demonstrates that transfected epidermal stem cells using a novel 3D transfection system significantly enhanced wound healing and may serve as an effective therapeutic agent and gene delivery method for wound treatment.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

This study found that GLI2 plays a key role in activating follistatin, an activin/BMP antagonist, in response to hedgehog signaling in human epidermal cells, with implications for hair follicle development and basal cell carcinoma.

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.
