This study found that dihydrotestosterone alters the balance of Wnt pathway regulators in dermal papilla cells, hindering hair follicle stem cell differentiation and contributing to hair follicle miniaturization.

This case report identifies a novel LIPH gene mutation linked to autosomal recessive woolly hair/hypotrichosis in a Japanese boy, expanding the spectrum of known mutations associated with this condition.

This study suggests that enhancing endocannabinoid tone with an EMT-inhibitor may have anti-inflammatory effects and slightly increase sebaceous lipid production, which could be beneficial for dry skin conditions.

In this animal study, zinc deficiency in mice was linked to disrupted hair cycles and impaired hair regrowth, which were reversed by zinc supplementation.

This study explored the role of nine specific miRNAs in human hair follicles, revealing significant miRNA/mRNA correlations for miR-24, miR-31, and miR-106a and identifying target genes involved in hair biology.

In this study, researchers explored the effects of various medications on eye health, noting that systemic and local ophthalmic drugs can lead to both widespread and specific ocular side effects, with serious adverse events most associated with neurotropic, immunotropic, and antitumor medications.

In this review, researchers reported that anorexia nervosa leads to widespread medical complications across all body systems, particularly at low body weights, and these complications are primarily treated through nutritional rehabilitation with a multidisciplinary team approach.

This study found that a decrease in estradiol levels in women is associated with increased hair shedding due to weakened anchoring of telogen hairs.

This article discusses the rationale, design, and significant findings of the long-running Rotterdam Study but reports no new clinical results.

This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

This review discusses sex differences in the neuroendocrine response to stress, focusing primarily on rodent studies, and highlights open questions about the roles of gonadal hormones and sex chromosomes.

This review discusses the effects of visible light on human skin, highlighting its role in pigmentation, thermal damage, and the treatment of several skin conditions, while noting limited sunscreen protection against it; no new clinical results are reported.

The researchers reported that hair follicle development and commensal microbe colonization promote the accumulation of regulatory T cells in neonatal skin, with the Ccl20-Ccr6 pathway playing a key role in this process.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

Myrtle has various health benefits and potential for medicine development.

This review discusses various nanoparticles and nanoemulsions being investigated for transdermal drug delivery and reports no clinical results; it highlights potential applications in treating alopecia, wound healing, psoriasis, and melanoma.

This review discusses various strategies to enhance drug delivery through the skin barrier, highlighting liposomes as promising carriers for increased dermal concentrations in topical therapies, but reports no new research results.

This review discusses the application of liposomes in dermatology, highlighting their therapeutic value for drug stabilization, skin penetration enhancement, and treatment of hair follicle-associated disorders, but reports no new clinical results.

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

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.

This article reviews the history and impacts of direct-to-consumer advertising of prescription drugs in the U.S. and reports no new research findings; it discusses implications for health policy debates.

This study found that activation of the TRPV3 ion channel inhibits human hair growth by affecting hair follicles and outer root sheath keratinocytes.

This study found that SARS-CoV-2 hijacks the host factor IGF2BP1 to stabilize its RNA and enhance translation, and identified Cepharanthine and Trifluoperazine as potential treatments against the virus.

This review discusses the essential roles and complex regulation of PP2A in various physiological processes and reports no clinical results; the authors highlight the need for further mouse model research to explore PP2A's therapeutic potential.

In this study, researchers found that TCDD exposure accelerated differentiation and altered gene expression in human epidermal cells, indicating the epidermal barrier as a target of TCDD-activated AHR.

This study found that silencing clock genes BMAL1 or PER1 in human hair follicles increased melanin content and melanocyte activity, suggesting these genes influence pigmentation.

In this study, increased corticosterone from chronic stress prolonged hair follicle stem cell quiescence in mice, inhibiting regeneration, but restoring Gas6 expression overcame this inhibition.

This article reviews the hormonal and medication-related factors associated with acne development but does not present new research findings.

This study found that Sonic Hedgehog secreted by hair follicle transit-amplifying cells is essential for dermal adipogenesis and hair follicle growth by acting on adipocyte precursors.

This review discusses the potential role of steroid 5α-reductase inhibitors in treating neuropsychiatric disorders related to dopaminergic hyperreactivity but reports no new clinical results.
