Alopecia areata is complex, with genetic and immune factors, and animal models are key for future treatment research.

This study identified a 69 bp deletion in the KRT75 gene as the cause of the frizzle feather trait in chickens, affecting feather curling.

This study found that male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

In this study, the researchers identified the SPEF2 and PRLR genes as potential candidates associated with feather rate phenotypes in Shouguang chickens through combined genome-wide association and differential expression analyses.

This study suggests that the keratins found in reptile and bird skin appendages evolved independently from mammalian hair keratins, highlighting convergent evolution in these species.

A man's chest hair turned white after a shingles infection, possibly due to virus-damaged pigment cells.

This article discusses the impact of COVID-19 on skin health, highlighting various cutaneous manifestations and the need for dermatologists to adapt their practices during the pandemic, but it reports no new results.

This study identified a 195 bp duplication in crested chickens that causes large crest feathers and can be associated with cerebral hernia in some breeds, but not all.

This study found that 5-aminolevulinic acid significantly improved chicken sperm motility and increased mitochondrial membrane depolarization, while decreasing ATP levels.

In this study, hemp seed-derived exosomes (E40) showed potential for counteracting DHT-induced inhibition of feather follicle development in chicken embryos by modulating critical signaling pathways, suggesting a therapeutic approach for alopecia.

In this study, researchers examined chicken feather follicle tissues from differently colored chickens and found that the genes SLC45A2 and GPNMB are involved in promoting melanin deposition, which enriches understanding of the genetic mechanisms affecting feather color.

The researchers reported that scaffoldin, a protein identified in chicken embryos, likely plays a role in forming periderm granules and contributes to the soft cornification of embryonic epidermis.

This study demonstrated how cellular flows and tissue mechanics guide the topological transformations in avian skin, essential for feather follicle development from scales.

This study found that dietary yeast cell wall supplementation in broiler chickens increased certain immune responses compared to antibiotic treatments following immunization with sheep red blood cells.

This study found that a mutation in the BMP12/GDF7 gene is associated with the Naked neck trait in chickens, reducing neck feathering due to altered signaling pathways.

This study found that alkaloids isolated from Cucumis metuliferus fruit pulp demonstrated antiviral activity against IBDV in chicken embryo fibroblast cells and NDV in 10-day-old embryonated chicken eggs, while being non-cytotoxic.

This article reviews the interaction between sex hormone pathways and morphogenesis-related signaling in epithelial organ development, using a chicken model to propose testable hypotheses, but reports no new clinical results.

Skin problems are common in Bangladesh due to arsenic, prompt treatment of diabetic foot ulcers is crucial, maternal transmission causes most neonatal herpes, treatments for pediatric vasculitis are effective, the chickenpox vaccine works, more frequent UVB therapy helps psoriasis, certain jobs increase hand dermatitis risk, monoclonal antibodies treat psoriasis well, lifestyle affects psoriasis, alefacept improves psoriasis, imiquimod cream partially clears basal cell carcinoma, and iron may not help chronic hair loss.

This study supports the use of the chicken chorioallantoic membrane as an effective pre-clinical model for burn wound research and the screening of new therapeutic agents.

This article discusses the characteristics of human hair, its damaging processes, and the potential repair effects of immuno-cosmeceuticals, but it reports no new clinical results.

This review summarizes the roles of Wnt signaling in wound healing but presents no new clinical findings, suggesting potential for Wnt-based therapies to enhance tissue regeneration.

In this study, researchers found that the glabrous skin of the rat forelimb contains sparse Meissner corpuscles and Merkel complexes, with more slowly adapting afferents in the palm and rapidly adapting afferents in the digit extremity.

This source outlines common health issues in weanling gerbils, including skin infections often tied to beta-hemolytic Staphylococcus aureus, and obesity-related conditions like diabetes, as well as respiratory infections and musculoskeletal problems, without detailing specific new study results.

This study in mice found that overexpressing Sonic Hedgehog in basal cells caused skin anomalies and a lack of certain hair fibers, underscoring its key role in hair follicle development.

A specific hair protein variant increases the spread of breast cancer and is linked to worse survival rates.

In this study using zebrafish, four bisbenzylisoquinoline derivatives were found to protect hair cells from aminoglycoside-induced damage without reducing antibiotic efficacy, potentially leading to therapies for patients undergoing such treatments.

This study found that specific SNPs in the sheep FAT1 gene are significantly associated with wool quality traits, suggesting potential markers for improving wool crimp, fibre length, and fibre diameter in breeding.

This article reviews the generation of complex integument patterns through genetic, chemical, and environmental influences, with applications in tissue engineering, but reports no new experimental results.

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

This study reveals that β-catenin and retinoic acid are key regulators in the gene networks controlling the fate of skin appendages, such as scales and feathers.
