This review summarizes the current understanding of microRNAs in skin biology, highlighting their roles in processes like wound-healing and aging, without presenting any new experimental results.

This article reviews the role of microRNAs as epigenetic modulators in dermatology but reports no new clinical findings.

This study identified overexpression of certain immune-related genes and underexpression of genes in specific signaling pathways in premature androgenetic alopecia, suggesting potential new therapeutic targets.

In this study, researchers investigated the penetration and cellular responses to nanoplastics in human skin models with compromised barriers, finding that nanoplastics can penetrate the skin, accumulate in cells, and trigger inflammatory responses through specific signaling pathways.

This study observed that hair follicles in hair loss patients had increased levels of Propionibacterium acnes, potentially linked to elevated immune response gene expression in miniaturized hair follicles.

This study found that alopecia in captive Rhesus macaques may be linked to chronic hypersensitivity dermatitis with CD4+ cell inflammation, possibly influenced by altered housing and reduced pathogen exposure.

IL-1 receptor absence in mice leads to skin cysts and changes in immune response after UVB exposure.

This study in SPF lambs found that primary and secondary orf virus infections trigger similar skin responses, but the primary infection caused a more severe and prolonged reaction.

This study suggests that human embryonic stem cells may improve skin graft quality and functionality by enabling the identification and amplification of early ectodermal progenitors, pending confirmation from preclinical studies.

This study found that dengue virus infection caused inflammation and cell death in human hair-follicle dermal papilla cells, which may contribute to increased hair shedding observed during the epidemic in Taiwan.

This study found distinct differences in protein expression and wound healing pathways between Acomys cahirinus and Mus musculus, highlighting potential targets for reducing fibrotic response in mammals.

This study found that mixtures used in permanent hair dyes had irritant effects on reconstructed human epidermis, while individual ingredients alone did not.

This study found an association between hydroxyl radical-modified SOD and alopecia areata, suggesting these modifications may lead to antibody induction in the condition.

This study found that repeated immunization against melatonin in Australian feral goats temporarily increased cashmere production and altered growth cycles, but these effects diminished after the first year.

This study reports that two mouse models of scarring alopecia exhibit similar patterns of hair loss progression despite histological differences in inflammatory cell localization and MHC class I expression.

This study suggests that an in ovo injection of CHIR-99021 promoted feather growth and follicle development in goose embryos by activating the Wnt signaling pathway.

This study found that injecting xeno-free, three-dimensional cell masses from human adipose-derived stem cells improved blood perfusion and preserved limb function in mice without causing tumors or toxicity, suggesting potential for treating severe ischemic diseases.

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.

Polyethylene alanine caused hair loss in young lab animals but not in adults, with hair regrowth occurring within 20 days.

This study found that oral probiotic supplementation over 12 weeks may improve hair growth, skin condition, metabolic health, and stress responses in Chinese adults with hair loss and a high risk of metabolic syndrome.

This review summarizes the link between acne pathogenesis and skin barrier dysfunction, noting that more severe acne correlates with greater skin barrier damage, but reports no new clinical results.

This genome-wide association study identified several genetic markers, including specific SNPs and HLA genotypes, associated with alopecia areata susceptibility in the Taiwanese population, highlighting key pathways involved in immune response and offering insights into the genetic origins of this autoimmune condition.

This study reports that a novel gain-of-function mutation in TMEM173, combined with polymorphisms in TMEM173 and IFIH1, results in a distinct clinical phenotype with features of SAVI, including alopecia and photosensitivity.

This study uncovered how Staphylococcus hominis transports an odor precursor molecule, potentially leading to new ways to control body odor production in humans.

This study evaluated the physicochemical characteristics, safety, and efficacy of six herbal and six synthetic shampoos and found that all products performed well in various tests, with no skin irritancy observed, suggesting that both types can be considered safe for use.

This study prepared and evaluated a polyherbal hair oil using plant-based ingredients, finding that it met standard parameters and effectively addressed hair problems such as growth and dandruff, with FDA approval for clinical use.

This study observed that a polyherbal hair oil made from virgin coconut oil and extracts of nine different herbs demonstrated effectiveness in promoting hair growth with a cooling effect and no reported side effects, based on various evaluated properties.

This article reviews recent imaging and genetic tool advances that enable in vivo study of hair regeneration and assessment of skin parameters, but it reports no new clinical results.

This study highlights the potential benefits of herbal soaps and shampoo bars as eco-friendly alternatives to conventional cosmetics, noting their antibacterial, antifungal, and antioxidant properties as well as sustainability advantages such as reduced plastic use and avoidance of synthetic chemicals.

In this study, researchers developed a GelMA-based gradient pH hydrogel that effectively reduced bacterial load and promoted fibroblast and endothelial cell proliferation, macrophage polarization, neovascularization, and hair follicle regeneration, offering a promising treatment for bacterially infected skin wounds.
