In laboratory settings, this study suggests that Serenoa repens and N-acetyl glucosamine with milk proteins may promote hair follicle vascularization through specific cellular interactions and actions.

This study suggests that hair loss disorders like Marie Unna hereditary hypotrichosis may result from mutations that disrupt post-transcriptional regulation of HR protein expression by PCPB2 interacting with Hr mRNA.

This review summarizes the roles of matricellular proteins in skin stem cell niches, highlighting their contribution to stem cell fate, self-renewal, and potential implications for wound healing and aging.

This study suggests that some keratin-associated proteins with antecedents found in non-haired animals may have roles beyond hair characteristics, possibly contributing to the evolution of hair follicles.

In vivo using the C3H mouse model, this study observed that BST2 expression occurs before hair loss in alopecia areata and is followed by an increase in epidermal γδ T cell numbers.

This study identified two single-nucleotide polymorphisms and three haplotypes in the KRTAP7-1 gene across yak, taurine, and zebu cattle, with the BOVIN-KRTAP7-1*A haplotype most prevalent.

This obituary honors Susan Lee Lindquist for her pioneering work in cellular protein folding and genetics, highlighting her significant contributions to science and mentorship in her nearly 40-year career.

This study suggests that human hard keratin proteins may be biocompatible materials, unlikely to cause rejection or allergic reactions based on their antigenicity in BALB/c mice.

In this study, a "frequent profile" of hair proteins was observed in 180 of 182 individuals, showing consistent electrophoretic bands characteristic of keratins, with rare deviations in two samples.

This study suggests that keratin expression in keratoacanthomas resembles that in the upper part of hair follicles, implying a potential origin, but it is indistinguishable from squamous cell carcinomas in terms of keratin reactivity.

This study introduced a method to isolate and separate microfibrillar proteins from human hair, identifying previously undetected glycine- and tyrosine-rich proteins.

This study found that combining mesenchymal stromal cells from adipose tissue and hair follicles with soy protein and β-chitin scaffolds significantly reduced wound healing time and improved skin regeneration in vivo.

In this study, azelaic acid was found to enhance UVB protection in bulge cells and, when combined with minoxidil, may promote hair growth through increased Sonic hedgehog protein expression in hair follicles.

In this study, no significant differences in cellular stress response or growth capabilities were found between FUE and FUT hair restoration techniques.

The mutation causes hairless mice due to mislocalized and dysfunctional HR protein.

This study identified nine novel KRTAP5 family genes associated with human hair formation, demonstrating preferential expression in hair roots and suggesting their role in hair development.

This study concludes that SPARC is likely a secondary response during the hair cycle's transitional phases, indicating tissue-remodeling processes similar to those in wound repair, rather than initiating these transitions.

A liquid protein diet caused hair loss in a young woman.

This review discusses recent research on the Dickkopf protein family's involvement in non-cancerous diseases and considers their potential as biomarkers and therapeutic targets without presenting new experimental results.

In this study, researchers linked SARS-CoV-2 infection to telogen effluvium in some COVID-19 patients by observing the accumulation of viral proteins in hair follicle cells, which may trigger stress responses and cell death, suggesting hair follicles as a potential target in COVID-19.

This study found that specific immune cell phenotypes, particularly CD25 on CD4 Treg cells, were causally linked to androgenic alopecia, suggesting potential targets for immune-based therapies.

This study found that lipids are highly correlated with hair curvature while proteins are not, reporting the largest number of hair lipids and identifying novel proteins and chaperones relating to different hair types for the first time.

This paper reviews strategies for modifying the structure and protein delivery of electrospun nanofibrous materials, emphasizing their potential to guide tissue repair and highlighting current challenges and future research directions in this emerging field.

This study suggests that while some evidence indicates potential efficacy of placental products for hair growth and inhibiting hair loss, the current scientific evidence is scarce and of low quality.

This paper reviews the benefits of using silk proteins as natural ingredients in cosmetics, highlighting their potential for improving skin and hair health due to properties like antimicrobial activity, UV resistance, and enhanced moisture absorption.

This study identified 193 plasma proteins associated with prostate cancer risk, validating 20 high-risk proteins including KLK3, and pinpointed potential drug targets like HSPB1, RRM2B, and PSCA through genetic analysis, offering new insights for biomarkers and treatments.

This study found that topical application of TGF-β mimic promoted enhanced wound healing and tissue regeneration in mice, suggesting its potential as a therapeutic option for improving wound healing.

In a keratinocyte-specific knockout mouse model, this study found that deleting GRK2 disrupted hair follicle homeostasis, causing cyst-like structures, abnormal growth patterns, and eventual hair loss, suggesting potential links to immune-mediated alopecias.

This study assessed three lactic acid bacteria-fermented proteins and found that F-WPI and F-SPI could normalize osteoclastogenesis markers in vitro, while F-SPI enhanced osteoblastogenesis markers, suggesting potential as dietary supplements for osteoporosis prevention, though further research into mechanisms is needed.

This study suggests that hemoglobin α expression in the epidermis is induced by oxidative stress and may function as an antioxidant, contributing to skin barrier function.
