This study using scRNA-seq on 96 skin biopsies from 51 healthy individuals revealed distinct cell signaling pathways in different skin sites, including unique pathways in facial and palmoplantar skin, which may explain their varying susceptibilities to skin disorders.

This study found that the addition of SPACE peptide significantly enhanced the penetration of amniotic membrane stem cell metabolites in mice, with only very mild irritation observed.

This study demonstrated immunological cross-reactivity between mycobacterial heat-shock protein 65 and human epidermal cytokeratin 1/2, suggesting that this cross-reactive epitope might play a role in skin diseases.

This study purified trichohyalin protein from pig tongue epithelium, characterizing its unique properties and structure, which may facilitate future functional research.

This study found that certain tandem repeats predict darker hair color across diverse ancestry groups and can contribute to a polygenic score for hair color, independent of SNP variation.

This study found that substance P and calcitonin-gene-related peptide have different roles in regulating hair growth in mice, with substance P promoting anagen progression and calcitonin-gene-related peptide inhibiting it.

In this study, researchers identified Tenascin-C as a marker for touch dome keratinocytes, which maintain themselves and can develop into Merkel cells following injury, showing they share molecular traits with various epidermal keratinocytes.

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, the researchers found no significant link between CAG repeat numbers in the androgen receptor gene and female pattern hair loss in a Chinese population.

Gene expression in wool follicles changes with growth cycles, offering insights into wool and human hair growth.

Keratin-associated proteins may have roles in various mouse tissues, not just hair.

In this study, cubosome and hexosome carriers with antimicrobial peptides showed varied efficacy, with cubosomes protecting peptides from degradation and enhancing bactericidal effects in some cases, while hexosomes lacked antimicrobial activity.

This article explores the potential applications of polyglutamic acid in cosmetics, discussing its benefits for skincare and haircare, but reports no new experimental results.

ATP-sensitive potassium channels are important for hair growth.

This study found that immunity to self-prion peptides could be induced in Lewis rats, but in older rats, it was associated with severe skin inflammation and hair loss.

This article reviews the genetic and protein interactions involved in hair growth, highlighting regulatory sequences, expression patterns, and potential genetic modifications, but presents no new experimental findings.

KRTAP10 proteins help form the hair shaft's tough outer layer by interacting with specific hair keratins.

This study suggests that the C-terminal of AHF is crucial for its binding to keratin bundles and modulating the keratin meshwork in hair follicles.

This study found that 'smart' peptide hydrogels improved wound healing in a rat model of partial thickness burns, achieving greater wound closure and faster debridement compared to a standard treatment.

This study investigated a patient with spinal and bulbar muscular atrophy who had 68 CAG repeats, revealing early onset and unique symptoms not previously documented in the condition.

This study found that trichocytic cytokeratins, typically found in hair, are also present in nails, filiform papillae of the tongue, and the epithelial reticulum of the thymus.

This study investigated peptidergic nerve fibers in sinus hair follicles of various mammals and found that CGRP fibers were more densely distributed than SP fibers across different regions of the follicles.

In this study, specific genetic polymorphisms in the KRT71 gene were associated with hairless and curly phenotypes in Sphynx and Devon Rex cats.

This review discusses the role of matriptase and its inhibitor HAI-1 in epithelial homeostasis and cancer development, highlighting their imbalance's link to cancer progression without presenting new experimental results.

This review suggests that topically applied peptides may offer a promising alternative for managing pain in chronic wounds, with additional potential benefits of anti-inflammatory and regenerative activities, but acknowledges the challenges of delivering these peptides across damaged skin barriers.
