This study found that the extraction-resistant structures in hair, feathers, and hagfish teeth are due to ε-(γ-glutamyl)lysine cross-linked proteins, emphasizing their role in maintaining the integrity of these materials.

This study found that fractional laser treatment significantly enhances the penetration and targeting of certain permeants, such as imiquimod and FD, to skin follicles, but not hydroquinone.

This study reports that a low concentration of chitosan induces callose deposition and slows root hair growth in Arabidopsis, suggesting an evolutionary conservation of this response to mild biotic stress across plant types.

This case report describes an 8-year-old German shepherd dog with pemphigus vulgaris whose symptoms were not adequately controlled by immunosuppressive therapy, but showed transient remission with heparin alone or combined with prednisolone.

This study found that Gp₄G increased hair length, papilla cell numbers, and versican deposition in treated animals, potentially through alterations in hair follicle phases and nucleotide concentrations.

This study found that mice lacking REDD1 experienced an expansion of dermal white adipose tissue through both hypertrophy and hyperplasia, suggesting a potential therapeutic target for skin adipogenesis regulation.

In this case study, two middle-aged patients with pruritic scalp erosions were diagnosed with localized pemphigus vulgaris, which resolved without relapse after treatment with low-dose oral prednisone and intralesional triamcinolone acetonide.

This source highlights the utility of cationic polymers in haircare products for protecting against hair damage from chemical treatments and grooming, and describes how microfluorometry can measure polymer deposition and penetration on hair fibers.

This study investigated the histogenetic relationship between basal cell carcinoma and hair follicles, revealing specific staining patterns of a monoclonal antibody in different skin tissues.

In this study, researchers observed that a noncanonical mechanism involving the γ-secretase-dependent, RBPj-independent Notch intracellular domain improves survival in Msx2-Cre mice by delaying hair follicle destruction and reducing disease severity.

This study found that a topical transethosomal system may enhance the skin penetration and deposition of naftifine compared to a marketed cream, potentially overcoming the stratum corneum barrier.

This review explores how various skin cell types contribute to photoaging driven by UV radiation, detailing their interactions and molecular mechanisms like oxidative stress and ECM degradation, ultimately offering insights for future anti-photoaging strategies.

In this study, topical piperonylic acid was found to improve wound healing in mice by activating EGFR and modulating gene expression related to the healing process.

This study found that hair follicles contribute significantly to caffeine absorption shortly after topical application, with a faster absorption rate compared to the stratum corneum.

This study demonstrates that extracellular ATP induced by UV radiation promotes melanin production in human melanocytes, suggesting ATP-induced purinergic signaling may influence skin pigmentation.

This study found that nanostructured lipid carriers with more soybean phosphatidylcholine provided better skin retention and follicular targeting for diphencyprone compared to other formulations and controls.

This review discusses the potential role of extracellular vesicles in modulating hair follicle dynamics and reports no new clinical results; future investigations may inform treatment strategies for skin disorders.

This study found that Er–YAG laser treatment significantly enhanced skin absorption and follicular delivery of antialopecia drugs, suggesting a potential laser-assisted approach to treat alopecia.

This study found that minoxidil applied to a damp scalp may increase drug penetration in vitro, potentially improving treatment effectiveness.

Hair follicles could be used for targeted drug delivery, with liposomal systems showing promise for this method.

This study found that high doses of ethyl acetate extract from Tridax procumbens can have specific toxic effects in rats, including organ damage and significant changes in some serum biochemical parameters.

A woman with X-linked chronic granulomatous disease developed lupus-like skin lesions, improved with treatment, suggesting a unique skin condition in carriers.

In this study, researchers identified key genes such as EDNRB2, GPNMB, TRPM1, TYR, and DCT that regulate melanin deposition in the breast muscles of black-boned chickens, contributing to their unique pigmentation during embryonic development.

This study found cutaneous keratinic amyloid deposition in dogs and identified cytokeratin 5 as an amyloid precursor protein, revealing new insights into the etiology of cutaneous amyloidosis.

In an animal study, researchers observed that a Chromolaena odorata layered-nitrile rubber transdermal patch significantly improved wound contraction, protein, hexosamine, and uronic acid levels, and collagen deposition in healing excision wounds in rats compared to a control group with an empty patch.

This review discusses recent advances in skin penetration mechanisms, specifically focusing on the enhanced understanding of the follicular pathway and its implications for transdermal therapies, immune system targeting, and nanoparticle safety.

This study found that chitosan nanofibrillar scaffolds accelerated skin wound healing in mice by enhancing cell adhesion, proliferation, and regeneration of epidermis and dermis compared to other forms.

This review discusses the influence of oestrogens on various skin components and highlights their modulatory roles and receptor pathways, but it reports no new clinical results.

This study found that combining platelet-rich plasma with adipose-derived mesenchymal stem cells significantly improved diabetic wound healing in rats by enhancing angiogenesis and modulating the Notch signaling pathway.

This study found that the ARL15 gene affects adipocyte differentiation and adiponectin secretion, and suggests that ARL15 haploinsufficiency may predispose individuals to lipodystrophy.
