This review discusses the role of the complement pathway in alopecia areata and reports no new clinical results; the authors suggest that targeting this pathway could offer treatment options.

This research describes methods to activate melanocyte stem cells during hair follicle regeneration and to isolate melanocytes from neonatal mouse skin, with the aim of studying melanogenesis for potential clinical applications.

In this case report, a rare instance of a primary cutaneous granular cell tumor with prominent overlying terminal hair growth in an adult is described, highlighting the importance of recognizing atypical presentations to accurately diagnose similar uncommon neoplasms.

In this study, high-resolution ultrasound imaging revealed that DHT administration in male C57BL/6 mice leads to increased epidermal and dermal thicknesses and decreased skin elasticity, simulating structural changes associated with Androgenetic Alopecia.

Three molecular subtypes of advanced skin T-cell lymphoma were identified, with potential biomarkers for predicting treatment response and disease progression.

This study observed that TBX3 mRNA expression levels were region-specific and correlated with pigmentation patterns in dun Mongolian horses, providing insights into the genetic mechanisms behind their distinctive Bider markings.

This study highlights the distinct distribution patterns of extracellular matrix components in the scalp skin of male and female androgenetic alopecia patients, with increased elastin staining intensity observed in male cases.

In this study, researchers examined androgen receptor activity in the adult mouse brain and found specific expression in key brain areas, which could inform understanding of cognitive side effects in humans undergoing androgen deprivation therapy for prostate cancer.

In this study, researchers observed that applying negative pressure to nude mice led to a significant increase in hair follicle growth and angiogenesis, suggesting potential for hair regeneration through mechanisms involving SOX-9, LHX-2, and β-catenin mediation.

This study found that decreased expression of the protein transglutaminase 3 with age may lead to reduced zinc levels in hair cuticles, contributing to hair thinning.

This study highlights that a novel radially aligned nanofiber scaffold with dual growth factor gradients significantly enhances wound healing, promoting cell migration, epidermal regeneration, and angiogenesis, ultimately leading to improved wound closure, immune regulation, and tissue remodeling compared to other groups.

Hair keratin protein might help heal mouth wounds faster.

This study assessed three lactic acid bacteria-fermented proteins and found that F-WPI and F-SPI could normalize osteoclastogenesis markers in vitro, while F-SPI enhanced osteoblastogenesis markers, suggesting potential as dietary supplements for osteoporosis prevention, though further research into mechanisms is needed.

This study suggests that hemoglobin α expression in the epidermis is induced by oxidative stress and may function as an antioxidant, contributing to skin barrier function.

This study observed that EZH2 expression scores in the epidermis, dermis, and hair follicles decrease with gestational age in human fetuses, and these scores were significantly higher in adults, indicating that lower EZH2 levels may be required for full skin differentiation and maturation before birth.

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 concluded that lenalidomide significantly induces the proliferation and migration of melanocyte stem cells, enhancing their differentiation into functional melanocytes in a mouse model.

This case report describes the presentation of a 32-year-old Iranian immunocompetent female diagnosed with Merkel Cell Carcinoma, highlighting the importance of early diagnosis and management to mitigate complications.

This study observed a tendency for patients with frontal fibrosing alopecia to have more androgen receptors in their scalp than healthy controls, though this difference was not statistically significant.

This study found that the immunological characterization of ichthyoses as psoriasiform or atopic patterns could help improve treatment, highlighting the need for targeted therapies to address itch and skin inflammation.

In this study, canine hair follicle stem cells were shown to be multipotent, capable of differentiating into various cell types like adipocytes in vitro.

This study examined Bcl-2 and COX-2 expression in Lichen Planus cases, highlighting their roles in apoptosis protection and inflammation, with results analyzed statistically.

This study found that mutations in the PADI3 gene, which is important for hair shaft formation, may contribute to central centrifugal cicatricial alopecia among patients.

This study found that claudins CLDN1 and CLDN3 are crucial for maintaining proper hair follicle structure in mice, and their dysregulation may lead to telogen hair loss.

This study found that their novel 3D-imaging method, ASAXA-μCT, identified shrinkage of sweat glands as a key factor in skin aging, which leads to dermal defects, decreased elasticity, and increased wrinkling and sagging.

This study found that Quantitative Mass Spectrometry Imaging offers precise localization and quantification of active compounds in skin tissues, demonstrating benefits over traditional LC-MS in drug penetration studies.

This study investigates the potential role of the corticotropin-releasing hormone system in the pathogenesis of lichen planus but does not report new clinical results, emphasizing the need for further exploration.

This study observed that keratin sponges showed comparable biocompatibility to a commercial positive control in mice, but keratin gels had slightly inferior biocompatibility.

This study successfully improved methods for isolating, culturing, and purifying rat hair follicle stem cells, demonstrating their high purity, strong proliferation, and potential for adipogenic and osteogenic differentiation in vitro, which could support advancements in tissue engineering.

This study observed that Platycarya strobilacea S. et Z. extract enhanced hair growth and improved hair follicle length and immune response in mice compared to control groups.
