This case report describes a unique instance of late-onset Björnstad syndrome in an 18-year-old female, mimicking androgenetic alopecia, and indicates potential improvement with JAK inhibitor baricitinib, highlighting the need for considering this syndrome in similar cases of patterned hair loss in young individuals.

This article reviews the potential uses of PDRN in regenerative and aesthetic medicine, noting promising results in various treatments but highlighting the need for further long-term studies to confirm their safety and effectiveness.

This abstract does not provide specific study results or findings, but it notes that the publisher is not responsible for the supplemental content's accuracy and functionality, directing any queries to the article's corresponding author.

This study found that the extract of Bidens pilosa L. improved dry eye symptoms associated with androgen deficiency in rats by enhancing tear production, stabilizing the tear film, and reducing lacrimal gland inflammation.

This study found that cPPARγ and dnPPARγ isoforms are differentially expressed in healthy human skin, suggesting that PPARγ modulators may have compartment-specific effects depending on isoform presence.

This study developed a novel method to analyze the effects of COL7A1 mutations using mRNA from peripheral blood mononuclear cells, aiding genetic diagnosis and potential therapies for dystrophic epidermolysis bullosa.

This review covers the mechanisms and reported clinical effects of Photobiomodulation therapy, particularly in the fields of plastic surgery and dermatology, without presenting new clinical results.

This study suggests that simple absolute threshold monitoring rules for compliance using the biomarker DHT perform similarly to more complex methods in the Prostate Cancer Prevention Trial.

This review discusses the diverse roles of PPARβ/δ in skin health and disease, including its involvement in skin wound healing and inflammatory skin conditions, without presenting new experimental results.

Photobiomodulation effectively stimulates hair growth and reduces hair loss.

This review highlights LTBP1 as a critical integrator in disease processes, showing its dual role in cancer progression and suppression, its pathological influence in fibrosis, and its contribution to various disorders, suggesting its potential as a biomarker and therapeutic target.

This case report describes perifollicular melanocyte regeneration in the affected skin of a patient with bullous pemphigoid, highlighting an underreported aspect of the condition in skin of color patients, and emphasizing the need for increased awareness and earlier diagnosis in this demographic.

This study developed a microneedle system using black phosphorus nanosheets and baicalin for treating androgenetic alopecia, finding it effectively enhanced drug penetration and follicular targeting while showing synergistic efficacy and safety in preclinical tests, including in vivo model efficacy against testosterone-induced hair loss.

In this study, researchers found that BST2 expression is significantly upregulated in skin sections of mice with alopecia areata, implicating BST2's role in the disease pathogenesis through the action of epidermal γδ T cells and macrophages.

This review suggests that PDRN shows promise as a safe and versatile regenerative agent for wound healing and other dermatological applications, based on its dual mechanisms and clinical evidence of efficacy.

This study found that the Bioengineered Exosomal Hair Growth Factors Complex (BEHC™) enhanced human follicle dermal papilla cell proliferation and reduced inflammatory markers in vitro, while significantly decreasing hair shedding and increasing hair density among participants with androgenetic alopecia in an open-label clinical study.

This research observed that mutations in the PTCH gene are common in both sporadic and hereditary basal cell cancers, suggesting a critical role of the PTCH signaling pathway in skin tumor development.

Methylated gene parts may cause finasteride-resistance in some enlarged prostate patients.

This study found that dermatology patients with tattoos or piercings may have a higher risk of body dysmorphic disorder tendencies and lower acceptance of their illness.

This study suggests that measuring cortisol levels in hair may serve as a useful biomarker for assessing mood in individuals with bipolar disorder over recent months.

DNCB is highly effective for treating alopecia areata with minimal long-term side effects.

This study found that PDCD4 protein expression is reduced in various skin cancers compared to normal skin, suggesting its potential role in preventing or treating certain skin cancers.

In this study, the anti-wrinkle effect of bone morphogenetic protein receptor 1a extracellular domain was significantly greater than that of retinoic acid in a mouse model, suggesting potential for BMP antagonists in skin or hair treatments.

Mutations in the ACTB gene cause Becker’s nevi and may lead to muscle issues in Becker’s nevus syndrome.

This study found that the mitotic arrest deficient protein MAD2B negatively affects TCF4-induced growth and proliferation of dermal papilla cells, which are vital for hair follicle development.

This study identified a new gene, mrp4, in mice, which suggests it may have a unique role in the growth and development of hair follicles in the ears and tails.

In this study, treatment with recombinant DKK2 was shown to significantly stimulate hair progenitor cell growth and enhance hair shaft elongation in ex vivo human hair follicle cultures by activating the Wnt/ẞ-catenin signaling pathway, suggesting a potential role for DKK2 in promoting hair growth.

This study suggests that finasteride may upregulate BTG2 and CD244 gene expression through differential methylation, indicating potential as a treatment avenue for medulloblastoma.

This study found that the protein p63 requires morphogenetic signals to regulate gene expression effectively during skin cell differentiation, highlighting its complex role in therapeutic reprogramming for conditions like epidermolysis bullosa.
