This study describes how manipulating the actin cytoskeleton, particularly through the gelsolin family proteins, may enhance regenerative healing in mammals, suggesting potential therapeutic pathways for improved wound repair.

Fibronectin is essential for hair follicle regeneration and may help rejuvenate aged skin.

This study shows that microdiffraction experiments reveal structural layers in keratinous tissues, each with different keratin types, potentially explaining their dual role as mechanical support and chemical barriers.

This study demonstrates the use of microscopy-guided laser ablation to create a highly structured 3D hydrogel-based organotypic skin model with folliculoid structures, potentially useful for studying hair follicle development or bioactive substance screening.

This study found that trichohyalin is expressed in various normal and pathological epithelia beyond hair follicle cells, where it is uniquely associated with filaggrin, suggesting a specific role in aggregating K6/K16-containing intermediate filaments.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

This study describes the use of a genetically engineered mouse model, mTurquoise2-Col4a1, to fluorescently label collagen IV and observe basement membrane dynamics during skin development, revealing its stability and pliability during rapid growth phases.

This study characterized the mouse profilaggrin gene, finding it structurally identical to its human counterpart, and noted differences in protein-coding regions that could impact epidermal differentiation.

This study developed a bilayer bionic skin scaffold that mimics the skin's structure to resist microbial invasion and enhance wound healing, with in vivo animal studies showing improved collagen deposition, neovascularization, and hair follicle formation.

This study developed a model showing that keratin elasticity in skin may be influenced by electrostatic and bridging interactions between keratin filaments, contingent on the balance of charges in the surrounding medium.

This study presented 3D images of human dermis, revealing fewer elastic fibers near hair follicles compared to other regions, which may aid future skin engineering efforts.

In this study, researchers mapped cysteine accessibility in wool keratins and KAPs, revealing that certain cysteines in keratin end domains and Types I and II rod domains are accessible and likely involved in forming disulfide bonds.

In this study, AMACO was found to be non-essential for the formation or function of anchoring cords in mice, despite its presence in the structure.

This issue information abstract introduces a collection of articles, including one on hair keratins' unique filament formation, without reporting new experimental findings itself.

This study observed unique ultrastructural changes in a 4-year-old girl with pili trianguli et canaliculi that may affect hair shaft surface characteristics due to inner root sheath alterations.

This study found that wool fiber surfaces damaged in processing tended to have cellular debris adhering to them, while undamaged surfaces did not show this interaction.

In this study, researchers used synchrotron X-ray imaging to examine rat vibrissa follicles, finding that despite variations in vibrissa length and follicle size, certain sensory structures remain consistent, suggesting specialized roles in sensory processing depending on the vibrissa type.

This study revealed the complex three-dimensional innervation of touch domes in cat forepaw skin, highlighting the extensive branching and unmyelinated endings associated with Merkel cell–axon complexes.

This study found that microporous electrospun scaffolds with a 70:30 collagen I to poly(ɛ-caprolactone) ratio significantly accelerated wound closure and dermal regeneration in full-thickness critical-sized skin defects.

This study re-examined the structure of lanceolate endings in rat vibrissae, suggesting that their apical cones may function as a transducer site for detecting hair movements.

This study found that the protein Formin 2 helps regulate cell-to-cell transport in thale cress by stabilizing actin filaments at plasmodesmata, with its absence leading to increased permeability and vulnerability to viral infections.

This study found that in murine dermis, fibroblast state switching between proliferation and ECM deposition plays a crucial role in tissue architecture and wound healing.

This study reported detailed three-dimensional ultrastructural observations of human hair and hair follicles using a modified preparation method, including morphological differences in hair bulb cell layers and surface projections on root sheath cells.

This study found that the Arabidopsis thaliana protein Formin 2 localizes to plasmodesmata and is crucial for regulating their permeability by anchoring actin filaments, which affects virus susceptibility.

This review discusses the roles of filaggrin and trichohyalin in keratinocyte differentiation and reports no new results; the authors introduce possible hybrid granules in tongue epithelia.

This study demonstrates that FMOD deficiency in mice alters TGF-β ligand and receptor expression during wound healing stages, leading to delayed wound closure and increased scar size.

This article reviews various microscopy techniques and their applications in dermatology but reports no new experimental results.
