This study demonstrates that keratin K2 is crucial for proper keratinocyte structure and function in specific mouse skin areas, and its deficiency leads to cellular aggregates and skin abnormalities.

This study found that Nrf2 activation protected keratinocytes from UVB damage but also caused thickening, inflammation, and cysts, limiting its therapeutic potential for skin protection.

In this study, it was observed that NIPAL4 mutations linked to autosomal recessive congenital ichthyosis lead to abnormal skin barrier function due to cytotoxic effects disrupting lipid structure and organization, which topical treatments only partially ameliorated.

This review discusses the multiple factors contributing to skin aging, including cellular changes and environmental influences, and highlights its recognition as a disease with significant implications beyond cosmetic concerns, without reporting new research results.

This review explores the immunological aspects of epidermal differentiation in loricrin knockout mice, offering insights into keratinization and potential intrinsic factors affecting immune function, but provides no new clinical findings.

The researchers found that corneodesmosin is crucial for maintaining skin barrier integrity and hair follicle architecture in mice, with its deletion leading to severe skin and hair abnormalities.

This review discusses advances and challenges in skin tissue engineering, focusing on developing 3D constructs for functional skin substitutes, and reports no new clinical results.

The document explains various skin conditions and their treatments.

This study found considerable variation in hair shaft proteomic profiles among Caucasian, African-American, Kenyan, and Korean subjects, with individual and site-specific differences observed.

This study used proteomic profiling to reveal significant individual and site-specific differences in human hair shaft proteins, which may improve the differentiation of hair based on ethnic origin and individual identity.

This study emphasizes the need for personalized hair care strategies based on in-depth diagnostics, taking into account scalp type, environmental factors, and the microbiome, suggesting that this holistic approach could improve hair condition.

This review discusses the mechanisms by which isotretinoin and hormonal therapy treat acne through their effects on sebaceous glands, reporting no new clinical results.

This review discusses common skin disorders in older women and their treatments, but it reports no new clinical results.

This study found that ablating centrosomes in developing epidermis alters keratinocyte division without majorly affecting differentiation, suggesting early epidermal development is driven by high proliferation and cell delamination.

In this study, Alox15 knockout mice exhibited disrupted skin integrity and increased inflammation, suggesting that Alox15-mediated resolvin D2 production is crucial for maintaining skin homeostasis by suppressing inflammation.

This study found that inhibiting AP1 transcription factor activity in the suprabasal epidermis of mice alters keratinocyte gene expression, reducing barrier integrity and mimicking human keratoderma.

This study found that centrosome ablation in developing epidermis triggers cell surveillance pathways, resulting in thinner skin and halted hair follicle growth, while later stages of epidermal growth may operate independently of basal progenitor division orientation.

Some treatments can improve skin's defense against damage, but overuse may cause other skin problems.

This study explores the correlation between sirtuins' expression, histone deacetylation, and redox status in young and old monozygotic twins to understand their role in age-related mechanisms.

This study suggests a potential link between proteasome function and nucleotide excision repair in animal models with defects in the NER pathway, with implications for ageing.

These guidelines review the management of complications and specific forms of congenital ichthyosis and report no new results; they summarize expert and evidence-based recommendations for clinicians.

This study found that defective cross-linking in hair cuticles is observable in a minority of mouse hair mutants, suggesting different proteins are involved in cross-linking across cell types.

This review discusses the unique dermatologic needs and conditions affecting women of color, noting specific skin and hair conditions but reports no clinical results.

This review highlights recent genetic research advancements in understanding hereditary hair diseases but reports no new study results, emphasizing the identification of genes related to both monogenic and polygenic hair disorders.

This chapter defines skin integrity as a blend of intact structural elements and adaptable functional capacity, highlighting its importance in maintaining skin health across various conditions but reports no new research findings.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

This review discusses the formation and structure of the cornified cell envelope in the epidermis, highlighting biochemical pathways and genetic factors, but presents no new experimental results.

Genetic mutations cause various hair diseases, and whole genome sequencing may reveal more about these conditions.

This review explores how adipose-derived stem cells contribute to skin homeostasis and highlights recent advances in their clinical applications in dermatology, but it reports no new clinical results.
