This review highlights the various causes and treatment options for alopecia, noting that while non-scarring types often see successful hair regrowth, scarring forms require early intervention to manage inflammatory destruction of hair follicles.

This study examines various methodological factors affecting hair cortisol concentration analysis, finding inconsistent results on the impact of factors like resuspension solution, hair weight, extraction duration, and hair-cutting method.

This study found that DK peptides demonstrated potent inhibition of 5α-reductase, suggesting they may be promising candidates for treating hair loss.

This study observed that the degradation product PTeCA significantly increased in hair treated with oxidative cosmetics, suggesting it could be a reliable marker for detecting such treatments, with a proposed PTCA cut-off value using PTeCA as the gold standard.

This study identified four genetic loci on chromosomes 6, 10, 16, and 18 that may contribute to susceptibility for alopecia areata and suggested shared genetic factors with psoriasis.

This study found that nitrate, rather than ammonium, significantly enhances phosphate starvation responses in plants through a regulatory cascade involving NIGT1, SPX, and PHR1 proteins.

This study indicates that reduced activity of the matriptase-prostasin proteolytic cascade is likely the cause of human autosomal recessive ichthyosis with hypotrichosis, as demonstrated using a novel mouse model.

In this study, researchers found that the absence of type I or type II keratins in mice leads to severe skin barrier defects, highlighting keratins' crucial role in epidermal structure and function.

This study suggests that Nox4 is a key factor in the hypoxia-induced enhancement of adipose-derived stem cell functions through reactive oxygen species generation.

OCT4 helps hair stem cells renew and fight aging, potentially aiding hair regrowth.

This study found that a topical gel formulation containing rice water demonstrated in vitro antioxidant activity and elastase inhibition, suggesting its potential as an anti-aging skincare ingredient.

In this study, a novel electrospun dressing patch made with radially oriented PHBV nanofibers and loaded with berberine was shown to significantly accelerate diabetic wound healing in mice, achieving 100% wound closure in 18 days while also demonstrating improved mechanical and anti-inflammatory properties.

In this study, researchers developed a biomimetic anti-inflammatory nanosystem (MM-CEP/NLCs) that significantly reduced the severity of acute lung injury in vivo by targeting and accumulating in lung inflammation sites, showcasing its potential for treating inflammation.

This study identified five FDA-approved drugs—cepharantine, clofazimine, metergoline, imatinib, and efloxate—as potential candidates for repurposing to interfere with viral entry in COVID-19 treatment.

This study found that stage-specific epigenetic changes, particularly involving the gene PDGFC, may affect wool fiber development in Zhongwei goats, potentially serving as a biomarker for fur goat selection.

This study found that platelet-rich growth factor significantly reduced the release of proinflammatory cytokines in an in vitro rheumatoid arthritis model.

This study found that dermal sheath stem cell characteristics are lost with aging in humans, affecting skin rejuvenation and structure, and identified specific proteins like Activin A influencing keratinocyte and fibroblast activity.

This study found that the S. epidermidis A/C lineage is more pathogenic due to its metabolic and genomic versatility, which allows it to adapt quickly from a commensal to a pathogenic lifestyle.

This study found that the water extract of Eclipta prostrata L. may protect skin cells against UVB-induced damage, likely due to its antioxidant properties and absorption of UVA and UVB radiation.

In this study, researchers developed a pH-sensitive dendritic polyglycerol nanogel to measure pH inside hair follicles using an ex vivo porcine ear model, finding that the pH increases from 6.5 at the skin surface to 7.4 in deeper follicle areas, without observed toxicity.

This study found that Morus alba root extract activates β-catenin in hair follicle dermal papilla cells, promoting the transition to the anagen phase and enhancing hair growth factor secretion.

This study identified a target relationship between miR-148a, miR-10a, and BMP7, suggesting these microRNAs influence dermal papilla cell proliferation and may regulate hair follicle growth.

In this study, in vitro and in vivo models showed that chrysin enhanced the efficacy of docetaxel and reduced its adverse effects in non–small cell lung cancer treatment.

In this study, fluoxetine was found to decrease proliferation and adipogenic differentiation of human adipose-derived stem cells, suggesting it may reduce fat accumulation by increasing autophagy-related gene expression.

This study found that lysophosphatidic acid increases mesenchymal stem cell proliferation and migration through signaling pathways and reactive oxygen species, implicating potential applications in stem cell expansion.

In this study, researchers used transcriptomics and modeling to uncover previously unknown cell populations and marker genes in developing hair follicles, providing insights into early cell fate establishment and offering tools for further research on skin appendages.

This study found that 3D-printed polyamine-modified hydrogels facilitate M2 macrophage polarization and exosome secretion, enhancing skin cell compatibility and promoting wound healing and hair follicle induction in an animal model through specific signaling pathways, suggesting potential for skin disorder therapies.

This study found that extracellular vesicles derived from hair follicle mesenchymal stromal cells demonstrated similar potential to those from adipose tissue in promoting cell proliferation and migration, enhancing angiogenesis, and protecting cells under stress, suggesting promise for chronic wound treatment.

This study found that crosstalk between fibroblasts and endothelial cells significantly contributes to hypertrophic scar formation by enhancing fibroblast activity through cytokine secretion, with pathway analyses suggesting molecular targets for potential therapeutic interventions.

This study provides evidence that Fernblock® upregulates antioxidant pathways in cultured keratinocytes, potentially protecting against damage from fine pollutant particles.
