This study examined vicuña skin and hair follicle structures, finding a high density of secondary hairs in fleece areas compared to belly and legs, and identified various types of cutaneous glands potentially important for chemical communication.

Animal hair fibers like wool and mohair are strong when dry, but vicuna fibers are very brittle.

In this study, experimentally induced weight loss in merino sheep led to a decrease in wool fiber diameter and increased expression of certain high sulfur and glycine-tyrosine proteins, potentially impacting wool quality and industry preferences.

This study reports that hair fibers degrade most in acidic sandy clay, while silicone oil treatment is effective for conserving various hair types and artifacts.

This study found that ectopic expression of FGF5s in transgenic Chinese Merino sheep increased wool length and greasy fleece weight compared to non-transgenic controls.

This review examines genetic variation in the ovine KRTAP1.1 gene and its potential impact on wool quality, reporting no new findings but suggesting opportunities for developing gene markers for wool and pelt traits.

This study presents a DNA-analytical method that can reliably identify and differentiate cashmere, fine wool, yak, and camel hair fibers in both untreated and processed samples.

This review discusses the use and sustainability challenges of luxury animal hair fibers in the fashion industry and reports no new research findings.

Improving knowledge and practices in animal fibre production is crucial to meet market demands and potentially revive natural fibres.

This review discusses dermatological issues in llamas, detailing common findings, parasites, and disorders, but reports no new clinical results; it highlights the need for recognizing normal skin variations and discusses potential treatments like zinc therapy for certain conditions.

In this study, amitraz was found to be an effective and well-tolerated treatment for resolving sarcoptic mange in alpacas, demonstrating no relapse over a 10-month follow-up.

This study on Indian dromedary camel breeds investigated the KRTAP7 protein, finding all four breeds shared an identical gene sequence, with 13 phosphorylation and glycosylation sites influencing hair characteristics, alongside predicted interactions with other biosynthesis-related proteins.

In this study, the expression of Gnαs was significantly higher in black mice compared to white mice, suggesting its potential involvement in coat color formation in mice.

This study found that in Liaoning cashmere goats, overexpression of the PIP5K1A gene enhances skin fibroblast proliferation, while interference with this gene reverses melatonin-induced proliferation, and PIP5K1A regulates certain miRNA expressions, suggesting a role in improving cashmere yield and quality.

This study identified a gene variant in the TRPV3 gene that may explain the suri alpaca phenotype, characterized by longer and less crimped fleece, suggesting this variant's involvement in the development of these hair characteristics compared to the huacaya phenotype.

This study identified polymorphisms in HGT-KRTAP7-1 and KRTAP8-1 genes in Argentine llamas that may impact fiber characteristics by altering amino acid residues critical for keratin-associated protein properties.

This review discusses selection signatures and selective sweeps in fiber-producing animals and recommends further genomic investigations to identify genes related to important fiber traits, without providing new results.

In this exploratory in vitro study, treatment with spermidine increased cell viability and altered gene expression in human epidermal keratinocytes, suggesting potential benefits to cellular health and function, though effects on mitochondrial markers were not significant.

This research found that variations in the KRTAP gene family are likely responsible for the diverse hair phenotypes seen among mammals, influenced by gene repertoire differences, expression, and evolutionary factors.

In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

This study explored the genetic basis of fiber diameter in alpacas, identifying candidate genomic regions including four significant areas on VPA6, VPA9, VPA29, and an unassigned scaffold, using whole genome association analysis and a custom SNP microarray.

This study found that sarcoptic mange significantly decreased vicuña and guanaco populations in San Guillermo National Park, Argentina, likely originating from mange-infected llama introduced nearby, raising the risk of local extinction.

This study reports that a sarcoptic mange outbreak, likely originating from mange-infected llamas from a governmental program, dramatically reduced vicuña and guanaco populations in San Guillermo National Park, Argentina.

This study reported that most androgenetic alopecia patients in Trujillo were male, aged 31–39, with a family history of the condition, showing specific hair loss patterns and a disease duration of 1–5 years.

In these studies, researchers found that Peruvian camelids reach mature skin follicle development early, with specific cuticular characteristics useful for distinguishing fleece types, while Bolivian llamas have a mature follicle apparatus present at birth.

This study identified genomic regions and genes associated with wool, live weight, body condition, and reproduction traits in Uruguayan Merino sheep, highlighting potential genetic factors influencing these characteristics.

In this study of Zhexi Angora rabbits, researchers found that the fine-wool group exhibited lower fiber diameters and a higher hair follicle density than the coarse-wool group, and they identified key candidate genes potentially regulating wool quality through RNA-seq and genome resequencing techniques.

This study found that a single application of 0.1% aqueous benzalkonium chloride solution effectively treated dermatomycosis caused by Trichophyton species in guinea pigs.

In this study, researchers assessed wool quality in sheep and found that the Gentile di Puglia breed, a Merino-derived Italian breed, exhibits finer wool through higher secondary follicle density compared to the non-merinized Sarda breed, suggesting its potential for sustainable wool production.
