This review discusses the complex genetic factors contributing to androgenetic alopecia, highlighting the variability in genetic risk across different populations and the emerging understanding of personalized treatment strategies, but reports no new clinical findings.

This study found that mature dermal adipocytes have high plasticity, undergoing dedifferentiation and redifferentiation, which plays a significant role in hair cycling and wound healing.

In this study, researchers found that extrafollicular progenitors marked by Hic1 are the main contributors to reparative fibroblasts in wound repair, with potential to modulate healing outcomes through genetic and pharmacological interventions.

This study observed that the loss of H3K9me3, via the ablation of Suv39h1, Suv39h2, and Setdb1 in embryonic mouse epidermis, disrupts skin development processes such as keratinocyte differentiation and hair follicle formation, highlighting H3K9me3's crucial role in epidermal morphogenesis.

The study investigated immune cell patterns around the hair follicle infundibulum in androgenetic alopecia, revealing significant differences in immune signatures between patients with AGA and control donors, specifically noting an enrichment of CD4 cells in the patient group.

This study analyzed proteomic changes in Jiangnan cashmere goats' secondary hair follicles and found that the PLIN2 gene significantly impacts hair follicle growth cycles by affecting dermal papilla cell proliferation, offering insights into breeding strategies to enhance cashmere yield.

In this study, researchers found that both Wnt/β-catenin and Hedgehog signaling pathways must be activated in wound fibroblasts to promote hair follicle neogenesis in mice, suggesting these pathways are crucial for regenerative healing strategies.

This study observed that gerbils exhibit a different wound healing mechanism compared to mice, with lower TGF-B1 expression and distinct tissue responses, yet achieve similar healing outcomes.

This study identified key genes and miRNAs involved in feather morphogenesis in Zhedong White geese, highlighting a negative correlation between FOXO3 and miR-144-y.

This study identified four immune-related signaling molecules (LGR5, PTN, JAG1, and DKK1) associated with keloid, suggesting their potential role in its pathogenesis and as targets for new treatments.

This study provides a detailed analysis of cell subpopulations in a mouse model of wound-induced hair follicle regeneration, revealing specific cellular dynamics and heterogeneity that may influence hair follicle neogenesis.

In this case series, low-dose oral metformin was associated with improvements in symptoms and gene expression changes in Black female patients with treatment-resistant central centrifugal cicatricial alopecia, suggesting a potential therapeutic role for metformin in managing this condition.

This study explored the molecular mechanisms determining the identity of keratinocytes and corneal epithelial cells, finding that miRNAs from the Gtl2-Dio3 region, which regulate key signaling pathways, play a significant role in cell identity through the Hox/Gtl2-Dio3 miRNA axis.

This research re-analyzed single-cell gene expression data from a mouse model, confirming that certain genes involved in the EDA-EDAR and WNT pathways are crucial for skin appendage development, suggesting that their restoration may mitigate the effects of hypohidrotic ectodermal dysplasia in children.

This study identifies a polygenic basis for atypical recurrent flank alopecia in Cesky Fousek dogs through genome-wide association analysis and gene expression profiling, highlighting several metabolic pathways involved in the condition.

In a conditional knockout mouse model, this study found that loss of the transcription elongation factor SPT6 in basal keratinocytes led to psoriasis-like skin inflammation and delayed wound healing, suggesting SPT6 plays a crucial role in maintaining epidermal immune quiescence by suppressing proinflammatory NF-κB signaling.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

This study suggests that activating retinoic acid signalling can inhibit Wnt signalling and induce regression in certain skin tumors, providing potential therapeutic strategies for tumor regression.

This study found that the dermal papilla of the hair follicle regulates stem cell quiescence and regeneration by modulating Shh and Wnt signaling pathways, highlighting the importance of signaling cross talk in regeneration.
