This study used electron microscopy to identify a distinct dendritic cell in the human epidermis, similar to the melanocyte, with unique structural features and variable melanin content.

This study found that hemoglobin α is upregulated in epidermal keratinocytes after UV exposure and may function as an antioxidant, particularly for hair follicle stem cells.

This letter to the editor discusses an observed case of hair repigmentation linked with etretinate therapy but reports no new research findings.

This study found that overexpression of erythropoietin disrupted hair growth in mice by affecting dermal fat lipogenesis and lipolysis, leading to poor hair follicle development and truncal alopecia.

This study found that polymorphous light eruption (PLE) may include a wide range of conditions, requiring careful differentiation from similar skin disorders such as benign summer light eruption.

This research found that escin, when applied topically, enhances blood flow in human skin and promotes changes in endothelial cell signaling pathways, suggesting potential benefits for improving cutaneous microcirculation.

In this study, whole-genome sequencing of Lanping black-boned sheep identified ERBB4 and ROR1 genes as potentially important in their distinctive hyperpigmentation, enhancing understanding of their genetic evolution from Lanping normal sheep.

This study presents a two-photon imaging method to visualize low-threshold mechanoreceptor axon terminals in live mouse forepaw skin, enabling repeated high-resolution imaging to study sensory circuits during development and adulthood.

A man with a rare skin condition and a new gene mutation developed high calcium levels due to his treatment.

This case report describes a 3-year-old male with X-linked ichthyosis and associated neurologic abnormalities, identifying an unusual cortical development malformation and suggesting that abnormal hair banding may assist diagnosis.

This study identified Sciellin, a new protein precursor to the cornified envelope in keratinocytes, with unique solubility properties hinting at its potential role in envelope assembly.

This paper presents two cases of rare intraorbital ophthalmic artery aneurysms associated with arteriovenous malformations and discusses their clinical presentation, pathogenesis, and management, but reports no new clinical outcomes.

In this study, overexpressing TSPO in the mouse hippocampal dentate gyrus led to significant anxiolytic and antidepressant-like effects, partly through increased allopregnanolone biosynthesis.

This review highlights how the development of forensic DNA phenotyping systems like IrisPlex, HIrisPlex, and HIrisPlex-S has advanced criminal investigation by accurately predicting physical traits such as eye, hair, and skin color from DNA, thereby improving the precision and relevance of forensic applications.

This study reported that high ornithine decarboxylase expression and decreased keratin K1 and K10 expression may serve as useful markers for early stages of tumor development in mouse skin.

This review discusses central serous chorioretinopathy, detailing its etiology, associated factors, diagnostic imaging, and therapeutic options, but provides no new clinical findings.

This study found that mitochondrial oxidative phosphorylation in epithelial cells is necessary for proper enamel formation and odontoblast differentiation in developing incisor teeth in K320E-Twinkle Epi mice.

In this study, researchers identified compound heterozygous variants in the MBTPS1 gene associated with ectodermal dysplasia features in a 14-year-old female, broadening the known disorder spectrum linked to these genetic mutations.

This case report highlights a 33-year-old male initially misdiagnosed with Neuromyelitis Optica, whose symptoms may improve with biotin treatment due to late onset biotinidase deficiency.

This article reviews the impact of H2O2-redox homeostasis on hair follicle pigmentation via tyrosinase and associated mechanisms, discussing primarily findings from murine models without providing new clinical results for humans.

Among families with pediatric brain disease, this study identified over 200 novel genetic causes, revealing potential treatment points using drug repurposing or nutritional supplementation.

This report describes a case of widespread Porokeratotic eccrine and hair follicle nevus in a 15-year-old woman with keratitis-ichthyosis-deafness syndrome, involving both eccrine ostia and hair follicle infundibula.

This case report suggests that using encapsulated retinol in polylysine may effectively treat actinic keratosis with minimal irritation, potentially providing a safer alternative for frequent use.

This study observed that transgenic mice with overexpression of HE4 developed keratitis and severe corneal opacity, suggesting that HE4 may significantly influence keratopathy and inflammatory responses in the eye.

This case report describes a giant pigmented tumor of the scalp in a 47-year-old woman and suggests a possible dual origin involving neural crest differentiation.

Polarizing light microscopy can easily and reliably diagnose congenital keratinizing disorders like Netherton syndrome.
