This study used rapid-freezing immunocytochemistry to successfully map the ultrastructural localization of hair keratins in human scalp hair, primarily finding them in macrofibrils in the cortex and endocuticle.

This study identified differentially expressed microRNAs between back and belly skin in Rex rabbits, highlighting their potential roles in skin development processes.

In this study, researchers found that activating RORA in hair follicle stem cells reduced the expression of cytoskeleton-related genes, affecting cell migration and adhesion, which may aid in understanding hair follicle development and potentially inform alopecia treatments.

This study found that keratin filament networks in SG1 cells of mice undergo dynamic changes during cornification, impacting the barrier function of the stratum corneum.

In this study, researchers observed that mechanosensory neurons initially develop similar morphologies across different skin regions but diverge post-natally, adapting to the type of skin they innervate, with bone morphogenetic protein signaling crucial for forming Meissner corpuscles in glabrous skin.

This study identified a new cis-regulatory element in the mouse Hr gene that influences its expression in skin and brain cells, highlighting a complex molecular network involved in hair follicle formation.

This study found that α-melanocyte-stimulating hormone may modulate inflammation in skin connective tissue by inhibiting proinflammatory effects in fibroblasts.

This study identified the presence of recognizable organelles, such as lysosomes and mitochondria, in both the keratinized fiber and the hardened inner root sheath of the Romney wool follicle.

This study reports that Ca 2+ binding alters the dynamics and surface properties of PKD-like domains in Clostridium histolyticum collagenases, enhancing their stability and potentially aiding in collagen-targeting vehicle development.

This study cataloged several long non-coding RNAs and microRNAs in cashmere goat dermal papilla cells, suggesting these non-coding RNAs may play a role in hair follicle stem cell activation and hair growth.

This study found that the wavy coat trait in Nakano cataract mice is polygenic, involving major and minor genes, and resembles human curly scalp hair associated with the PRSS53 gene alteration.

In this study, researchers identified thousands of mRNA, lncRNA, circRNA, and miRNA transcripts involved in different hair follicle stages of Rex rabbits and highlighted significant gene expression changes and pathway enrichments, providing insights into the regulatory mechanisms of hair development in these animals.

This study reports that the differential expression patterns of three retinaldehyde dehydrogenases suggest a regulated need for retinoic acid synthesis in various organs during late mouse organogenesis.

This study reports that expressed mouse type Ia and type IIa trichocyte keratins were successfully assembled into intermediate filaments in vitro, while also suggesting that disulfide bond cross linking enhances their stability.

This study observed that Ptprq mutant mice exhibit significant abnormalities in hair bundle structure and vestibular dysfunction, suggesting similar issues may contribute to hearing loss and vestibular problems in humans with PTPRQ mutations.

This study identified the rough coat mutation in mice, but found that LOXL is not the causal gene, although its downregulation might contribute to related phenotypic changes.

In this study, researchers investigated changes in ribosomal RNA modifications associated with stress-induced cellular senescence in human skin cells, identifying potential biomarkers and targets for interventions to mitigate skin aging.

This study identified that mouse MILL1 and MILL2 are glycoproteins distinct from human MICA/B, primarily due to their association with β2-microglobulin and TAP-independent surface expression.

This study found that calcitonin‐gene‐related peptide immunoreactive sensory axons in rats are predominantly involved in tissue maintenance rather than nociceptive functions.

Cats' hairy skin has different touch receptors connected by myelinated fibers.

Scalp hair follicle cells help protect and heal skin in certain skin conditions.

This study observed that deleting ARNT in keratinocytes of mice reduced zigzag hair production and altered hair follicle differentiation, likely by affecting the expression of specific cyclin-dependent kinase inhibitors.

This study confirmed the localization of CK19 and vimentin in skin cells, with CK19 linked to hair growth and vimentin stabilizing fibroblast structure.

This study characterized hair from a patient with a ribosomopathy and identified distinct differences, including reduced hair thickness and lipid content, compared to family members.

This study found that the mammalian hairless gene encodes a corepressor protein that interacts with thyroid hormone receptors, providing insights into hair loss syndromes in humans and mice.

In this study using Angora rabbits, researchers found that the FRZB gene inhibits hair follicle development by modulating the Wnt/β-catenin signaling pathway, affecting the expression of various genes related to this pathway and altering cell proliferation and apoptosis.

This study concludes that SPARC is likely a secondary response during the hair cycle's transitional phases, indicating tissue-remodeling processes similar to those in wound repair, rather than initiating these transitions.
