This article reviews the complex structure and molecular composition of hair keratins, highlighting their self-assembly process and implications for keratin extraction techniques, but reports no new experimental results.

This study reports that trichocyte intermediate filaments from rat vibrissae and human hair follicles may contain a hollow region at their core, suggesting unique structural properties.

This study identified molecular elements controlling the expression and stabilization of THH protein in hair follicle cells, revealing key mechanisms that support hair shaft development in mice.

This study found that Plinest injections improved skin hydration and elasticity in the face, neck, and décolleté and were well-tolerated, with high patient satisfaction over a 4-month follow-up.

In this study, researchers found that supramolecular peptide self-assembling materials derived from Pacific oysters exhibit promising effects for skin wound healing in vitro and in vivo, demonstrating procoagulant, antioxidant, anti-inflammatory, and regenerative properties that suggest potential as a natural treatment option.

This article reviews the potential uses of PDRN in regenerative and aesthetic medicine, noting promising results in various treatments but highlighting the need for further long-term studies to confirm their safety and effectiveness.

This study found that the transcription factor Trps1 acts as a novel regulator of the Wnt signaling pathway and early hair follicle progenitors in developing vibrissa follicles in mice.

This study found that CTHRC1 is crucial for sweat gland function and vascular network integrity in mice, and its administration improved sweat gland performance by reconstructing nearby blood vessels.

This article reviews the classification and complexity of keratin protein groups in hair follicles, but reports no new experimental results on their transcriptional events.

This study suggests that a position effect disrupting TRPS1 expression may be linked to hypertrichosis in both Ambras syndrome in humans and a similar phenotype in Koa mice.

This study developed a new competitive 5alpha-reductase inhibitor with an IC(50) of 0.84 microM using a novel chemical structure.

This study found that the stability of the coiled-coil structure in human hair keratin is maintained by ion-pairing and hydrophobic interactions, which are disrupted as pH approaches 7.0.

In this study, researchers found that substance P and calcitonin-gene-related peptide have distinct roles in the regulation of hair growth in mice, suggesting potential therapeutic targets for hair growth manipulation.
