This study observed that Merkel cells and their associated somatosensory axons in mouse skin exhibit significant plasticity, remodeling dynamically to maintain homeostasis. Axonal branching patterns were notably influenced by Merkel cells, suggesting epithelial-neural interactions play a key role in axonal plasticity and patterning.

This review discusses the developmental plasticity between teeth and taste buds in cichlid fishes and reports no new experimental findings, highlighting potential implications for craniofacial organ patterning and regeneration.

In this study, researchers found that significant transcriptomic changes occur in the skin of Dezhou donkey foals as they age from newborns to one year old, involving gene expression shifts that may enhance skin barrier function and hair follicle development, while reducing collagen synthesis.

Hox genes control hair follicle stem cell regeneration in different body regions.

This review found no significant evidence supporting postpartum telogen effluvium as a distinct condition, suggesting its incidence is uncertain and possibly negligible.

This study reports that Wise is expressed in specific patterns during the morphogenesis of chick embryos, particularly in regions associated with known signaling molecules like Wnt, Bmp, and Shh.

This study identified a new mouse mutation associated with noninflammatory proliferative skin disease and hair abnormalities, drawing parallels to human conditions like Netherton's syndrome and monilethrix.

This report describes the successful treatment of dermatophytosis due to Trychophyton spp. in a 2-month-old kitten using ketoconazole cream, fish oil, multivitamin syrup, and sulfur soap, resulting in significant improvement in the skin condition after four weeks.

This report identified longitudinal grooves in the hair shafts of four children, diagnosing them with uncombable-hair syndrome.

This study found that tribuloside, a flavonoid from Tribulus terrestris L., enhances melanin production in human melanocytes, zebrafish, and human skin samples without causing toxicity, potentially through inhibiting PDE to increase cAMP levels and promote the melanin biosynthesis pathway.

This source underscores the need for a multidisciplinary effort to raise awareness of Demodex and demodicosis, suggesting that prioritizing research, diagnostics, and treatment development could enhance global health outcomes and improve quality of life for affected individuals.

This study investigated the molecular mechanisms of hair follicle morphogenesis in Ordos fine-wool sheep, identifying differential genes related to primary and secondary hair follicles, and providing important insights for improving wool quality and breeding strategies.

This abstract provides no results; it is a website notification about cookies and general access to JAMA content.

In this case study, an 18-year-old woman's triangular alopecic patch diagnosed as temporal triangular alopecia was considered non-progressive and had no impact on her quality of life, so no treatment was initiated.

This study found that sheep possess a polymorphic KAP8-2 gene that shares high sequence identity with the KAP8-2 gene in goats and reindeer.

This study found that the formation of the fibre cuticle surface in Merino sheep is similar to the epidermal stratum corneum process and not from a modified plasma membrane as previously thought.

In this study, the authors reported a case of alopecia X in a German Spitz dog and found that treatment with orchiectomy and melatonin resulted in partial hair regrowth and improved the dog's dermatological condition.

The study characterized the transcriptional changes in porcine SKP cells transitioning to fibroblast-like cells, indicating potential roles for specific signaling pathways in this cell fate transition.

This study identified a novel keratin-associated protein, KAP24.1, which is specifically expressed in the human scalp and located in the hair cuticle.

This report highlights a case where dermoscopic observation of corkscrew hairs in a young woman led to the diagnosis of trichotillomania, emphasizing its role in distinguishing this psychiatric disorder from other forms of non-scarring alopecia and highlighting the importance of timely intervention.

This study found that, in mice, different precursor populations give rise to Merkel cells in hairy versus glabrous skin, but their formation is controlled by a common genetic program involving FGFR2 signaling.

This study found that Demodex infestation was present in 21% of healthy volunteers, with higher rates in older individuals and more common in PUM personnel than students.

This case report describes a male cat with demodicosis primarily attributed to Demodex cati, suggesting the generalized disease may have been exacerbated by pruritus related to flea infestation.

In this study, gamma benzene hexachloride washes successfully resolved skin disease in guinea pigs affected by Trixacarus caviae, after confirmation via skin scrapings.

This study identified novel genetic variations in the KRTAP22-2 gene among eight sheep breeds but found no association between these genotypes and wool fibre traits, indicating possible species-specific differences compared to goats.

This study reported six pediatric cases of temporal triangular alopecia and highlighted the use of trichoscopy to distinguish it by detecting a distinctive carpet of vellus hair, helping to differentiate TTA from other hair loss conditions.

In this study, researchers identified loss of function variants in the HR gene as likely causes of the distinct roaning hair coat seen in lykoi cats.

This entry does not provide an abstract or new research findings, so no specific results are available for summary.

Some human genetic markers work for genetic studies in pig-tailed and stump-tailed macaques, which can help in their conservation.

This case report describes a unique presentation of porokeratotic eccrine ostial and dermal duct nevus with lesions on the dorsum of the hand and a focal lichenoid infiltrate, differing from typical palm and sole involvement.
