This study found that overexpressing the BMP inhibitor Noggin in transgenic mice led to a significant loss of nontylotrich hair follicles, suggesting a critical role for BMP signaling in hair follicle morphogenesis and cycling.

In this study, finasteride doses as low as 0.2 mg per day significantly reduced both scalp skin and serum DHT levels in men with androgenetic alopecia.

This review discusses treatments for chemotherapy-induced alopecia, highlighting scalp cooling for hair loss prevention and 2% topical minoxidil for regrowth acceleration as effective options, but reports a need for more rigorous trials to validate promising new therapies.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.

This review found that patients with alopecia areata may have lower levels of vitamin D, zinc, and folate, but conflicting evidence precludes definitive clinical recommendations for micronutrient supplementation.

This review discusses the pathophysiology of sleep disturbance in children with atopic dermatitis and highlights the need for further research on management strategies, but provides no new clinical results.

In this study, topical CUR61414 was effective in inhibiting basal cell carcinomas in mice, but no clinical activity was observed in human trials.

This article discusses the bi-compartmental organization of hair follicle stem cell niches for balancing stem cell cycling and organ growth and proposes similar structures may exist in other adult stem cell niches but reports no new experimental results.

This case series reported that three pediatric patients with hidradenitis suppurativa showed decreased frequency and severity of disease flares after treatment with oral finasteride, with no significant adverse effects.

This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

This study found that amplifying Wnt signaling, either genetically or through topical application of liposomal Wnt3a, improved skin wound healing in a mouse model.

This article proposes a mechanistic model for how platelet-rich plasma therapy may stimulate hair growth in androgenetic alopecia by promoting vascularization and activating specific signaling pathways, but it reports no new experimental results.

This study suggests that CD8+ cytotoxic T lymphocytes play a crucial role in the development of alopecia areata, based on observations in rodent models that mimic human autoimmune disease.

This review discusses the role of peroxisome proliferator-activated receptors and their agonists in dermatology but reports no new clinical results.

The researchers found that inhibiting soluble epoxide hydrolase, either genetically or pharmacologically, delayed the onset of chemically induced seizures related to GABA antagonism in experimental models.

This study found that the creation of hair follicle lumens in mice is driven by the outward migration of keratin 79-positive cells, suggesting a novel mechanism for generating hollow cores in hair follicles.

This study found that RANK-RANKL signaling regulates hair renewal and epidermal homeostasis in mice, revealing its role in initiating hair growth cycles and maintaining skin cell activity.

This study found that high-dose oral zinc significantly influences hair growth in mice, showing both inhibition and promotion effects depending on the timing and duration of administration.

This review discusses the basic biology of apoptosis and its relevance to skin diseases, without presenting new research findings.

This review discusses the complex causes and treatment challenges of chronic inflammatory skin diseases, emphasizing the need for biomarkers to predict treatment responses; it reports no new clinical results.

This study suggests that cerebrospinal fluid levels of the neurosteroids allopregnanolone and pregnanolone correlate negatively with PTSD and negative mood symptoms, with potential sex-specific differences in synthesis enzyme blocks.

This study demonstrated that EdnrB signaling promotes melanocyte stem cell proliferation and differentiation, enhancing hair and epidermal melanocyte regeneration, especially under conditions of active Wnt signaling.

This review discusses the potential role of Wnt signaling in aging-related heart diseases and reports no clinical results.

This study reports that C3H/HeJ mice and DEBR rats serve as effective models for screening potential treatments for human alopecia areata, despite certain challenges in predictability and cost.

This study identified novel genetic associations with skin phenotypes such as age-spots, freckles, and hair characteristics in Japanese women, providing insights into the genetic basis of these traits.

This study found that activating Nrf2 in human hair follicles significantly reduced oxidative stress, lipid peroxidation, and protected against hair growth inhibition, suggesting a protective role for Nrf2 against redox insult in this context.

This review discusses the development and application of multiphoton microscopy in dermatology, highlighting its advantages and potential future research directions without reporting new clinical results.

This study found that testosterone and 5α-dihydrotestosterone induced apoptosis in dermal papilla cells from nonbalding scalp regions, suggesting a high androgen stimulus can trigger cell death related to androgenetic alopecia.

This review discusses how androgens may regulate wound healing and inflammation, noting that testosterone appears to inhibit healing and promote inflammation, but it reports no new clinical results.

This study identified that the enzyme CYP2B12 is skin-specific and likely plays a role in the metabolism of arachidonic acid, a key component in lipid signaling within sebaceous glands.
