This study found that cutaneous squamous cell carcinomas in mice infected with murine papillomavirus preferentially arise from Lgr5+ progenitor cells, while squamous cell dysplasia does not.

This synopsis reviews key dermatological advancements discussed at the British Association of Dermatologists meeting in 2011 and reports no new clinical results.

This review outlines recent advancements in understanding how micro-RNAs (miRNAs) influence hair regeneration, highlighting their role in stimulating hair growth and potential therapeutic approaches, while also addressing the challenges of clinical translation due to miRNAs' complex roles and delivery issues.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.

This case report emphasizes the need to consider Sertoli-Leydig cell tumors in the differential diagnosis of adnexal masses in patients with Peutz-Jeghers syndrome, noting that these tumors can present unusually with bilateral adnexal involvement.

In this case report, a 74-year-old woman initially diagnosed with androgenetic alopecia was later found to have secondary alopecia neoplastica due to morpheaform basal cell carcinoma of the scalp, illustrating the importance of recognizing subtle clinical features to prevent delayed treatment and potential local destruction.

Mindfulness reduces anxiety and depression in skin disease patients; dermatologists and psychiatrists often lack confidence in treating psychodermatological conditions.

Aldesleukin can treat certain cancers and increase HIV patient CD4+ counts but often causes severe side effects.

Some medications can improve skin conditions, while lifestyle factors like smoking and drinking may worsen them; treatments like monoclonal antibodies and imiquimod cream show promise for certain skin diseases.

This study found that activating hair follicle resident T cells in a human organ culture can induce an alopecia areata-like immune response, and that the drug farudodstat partially reduced this effect.

In this study, the researchers used a human hair follicle model to demonstrate that T cell stimulation can induce an alopecia areata–like phenotype, with cell proliferation and immune privilege collapse; however, the DHODH inhibitor farudodstat partially mitigated these effects by reducing T cell proliferation.

This review discusses the potential role of vascular endothelial cells as signaling niches influencing epithelial stem cell states in the skin, emphasizing the need for further exploration in this area.

This study identifies a specific cell population, PDGFRα+/Sca1+/CD34+ mesenchymal cells, which play a crucial role in regenerating hair follicles by promoting the downgrowth phase of the hair cycle, offering insights into organ morphogenesis and stem cell niches essential for adult hair regeneration.

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

In this retrospective study, patients with cutaneous squamous cell carcinoma located in highly sun-exposed areas had a higher risk of local recurrence compared to those with tumors in less sun-exposed areas, though metastasis rates did not differ between the groups.

In this study, researchers observed a high degree of plasticity in somatosensory axons innervating Merkel cells in adult mouse skin, with both epithelial and neural components exhibiting dynamic remodeling, highlighting intricate epithelial-neural interactions in maintaining homeostasis.

This study in adult mice found that somatosensory axons innervating Merkel cells in the skin are highly plastic, with significant remodeling in response to epithelial turnover, and that Merkel cells play a role in limiting axonal branching and promoting their maturation.

This review discusses the calcineurin/NFAT pathway's role in cutaneous squamous cell carcinoma, noting its involvement in tumor development, skin cell behavior, and the tumor microenvironment; it reports no new results.

The abstract reports that non-cultured cellular grafting has become a prevalent and cost-effective method for treating stable vitiligo, with safety and effectiveness confirmed by two decades of studies. It critiques strict legislative oversight, suggesting it might unnecessarily increase costs and limit patient access.

This study observed that stem cells from the hair follicle dermis share similarities with bone marrow-derived mesenchymal stem cells and have potential to form neural-like cells under specific conditions.

This review highlights recent advancements in microfluidics for 3D tissue model generation and discusses its applications in tissue engineering and high-throughput drug screening without reporting new experimental results.

This bibliometric analysis examines the research landscape of T cells in atherosclerosis and identifies key trends and emerging research areas, highlighting the field's stabilization over the past decade.

This study found that MDSC exosomes promoted partial hair regrowth and modulated immune responses in mice with alopecia areata, suggesting potential as a treatment for autoimmune diseases.

This study identified key cells and pathways needed for the development of touch receptor patterns in mouse skin, notably that certain keratinocytes are crucial for innervation patterns, while Merkel cells and BMP signaling have distinct roles.

This review provides an overview of how advancing imaging technologies, such as tissue clearing and intravital microscopy, are enhancing our understanding of tumor architecture and interactions between cancer cells and the tumor microenvironment, aiding both fundamental cancer research and the development of therapies.

This review discusses recent advances in imaging techniques for monitoring stem cells in vivo and reports no new results; it suggests directions for future development in endoscopic molecular imaging tools.

This review highlights the promise of small extracellular vesicles (sEVs) as biomarkers for sepsis, emphasizing their potential to improve early detection and guide therapeutic decisions by reflecting the immune status and pathogen presence in patients.

This study compared RNA-seq results from horse plucked-hair and skin-biopsy samples, finding that plucked hairs were enriched with hair-follicle keratinocytes, while biopsies showed enrichment for other cell types.

This letter discusses how differentiating features in clinical and radiological findings can help distinguish pulmonary Langerhans cell histiocytosis and Birt-Hogg-Dube syndrome from lymphangioleiomyomatosis, noting overlapping symptoms but specific distinctive traits.
