research Hair Anatomy for the Clinician
Understanding hair follicle anatomy helps diagnose hair disorders.
research Polysaccharides from Traditional Chinese Medicines: Extraction, Purification, Modification, and Biological Activity
Substances from Chinese medicines show promise for immune support and disease prevention, but the way they are processed affects their effectiveness.
research The Pathobiology of Skin Aging
The document reviewed the complex phenomenon of skin aging, identifying it as a degenerative disease influenced by intrinsic and environmental factors, leading to issues like atrophy, fragility, defective repair, and reduced immunity. It highlighted the roles of stem cell dysfunction and genetic and epigenetic factors in skin aging, which also affected the microbiome and cancer development. Key changes in aged skin included altered keratinocyte and melanocyte distribution, reduced collagen and elastin, fibroblast structural changes, and increased matrix metalloproteinases, contributing to collagen breakdown. Aged skin also showed reduced immune function and increased susceptibility to infections. The review emphasized the need for future research to develop strategies to mitigate skin aging effects and improve public health strategies.
research Mutations in Three Genes Encoding Proteins Involved in Hair Shaft Formation Cause Uncombable Hair Syndrome
Mutations in three genes cause Uncombable Hair Syndrome, leading to frizzy hair that can't be combed flat.
research The Role of AUTS2 in Neurodevelopment and Human Evolution
The AUTS2 gene is linked to neurological disorders and may affect human brain development and cognition.
research Trichohyalin Mechanically Strengthens the Hair Follicle
Trichohyalin makes hair follicles stronger.
research Biochemical Evidence That Small Proline-Rich Proteins and Trichohyalin Function in Epithelia by Modulation of the Biomechanical Properties of Their Cornified Cell Envelopes
Small proline-rich proteins and trichohyalin help make epithelial tissues tougher and more flexible.
research Identification of Drug-Specific Public TCR Driving Severe Cutaneous Adverse Reactions
Researchers found a specific immune receptor in patients that causes severe skin reactions to a drug.
research A Novel Epithelial Keratin, hK6irs1, Is Expressed Differentially in All Layers of the Inner Root Sheath, Including Specialized Huxley Cells of the Human Hair Follicle
A new keratin, hK6irs1, is found in all layers of the hair follicle's inner root sheath.
research An Integrative View of Mammalian Seasonal Neuroendocrinology
The article concludes that better understanding gene regulation related to seasonal changes can offer insights into the mechanisms of seasonal timing in mammals.
research Keratin K15 as a Biomarker of Epidermal Stem Cells
Keratin 15 is not a reliable sole marker for identifying epidermal stem cells because it's found in various cell types.

research Gene Expression During Drosophila Wing Morphogenesis and Differentiation
Key genes are crucial for Drosophila wing development and could be insecticide targets.
research Human Epidermal Transglutaminase
The study from 1983 focused on human epidermal transglutaminase, an enzyme crucial for epidermal terminal differentiation. It required calcium or strontium and a free sulfhydryl group, similar to liver transglutaminase, but unlike plasma transglutaminase, it did not need proteolytic activation. The enzyme's activity increased significantly after treatment with organic solvents, heat, and chaotropic reagents, although these treatments did not change its molecular weight or immunologic properties. The research aimed to develop monoclonal antibodies for detailed structural analysis and to explore safe methods for modulating the enzyme's function in human epidermal diseases.
