Monocyte-derived dendritic cells play a key role in UVB-induced skin sensitivity and inflammation.

This study found that exosomes from human umbilical cord mesenchymal stem cells reduced oxidative stress and inflammation in UVB-induced skin injury in cell and mouse models, suggesting their potential for treating UV-damaged skin by influencing Nrf2 and NF-κB pathways.

This study found that co-culturing adipose-derived stem cells with hair follicle-derived melanocytes, combined with narrowband UVB, significantly improved pigmentary response in treating stable, resistant vitiligo compared to non-UVB treatments.

This study demonstrates that extracellular ATP induced by UV radiation promotes melanin production in human melanocytes, suggesting ATP-induced purinergic signaling may influence skin pigmentation.

This study measured caffeine content in ethanolic extracts of robusta coffee beans, finding 221.58 mg of caffeine per gram of extract, which aligns with known levels for Coffea canephora.

This study demonstrated that exosomes from human hair follicle mesenchymal stem cells can enhance collagen production, promote cell proliferation and migration in human dermal fibroblasts, and reverse signs of UV-induced skin aging in mice, potentially via a miR-125b-5p/TGF-β1/Smad signaling pathway.

This study found that p21 is much more highly expressed in normal melanocytes compared to melanoma cells, suggesting a potential target for preventing melanoma progression through cell cycle repair processes.

In this study, patients with generalized vitiligo treated with a combination of oral compound glycyrrhizin and UVB light showed the most effective repigmentation and disease stabilization compared to other treatment groups.

This study found that Bcl-xL deficiency in mice increased apoptosis and resistance to skin tumor development, highlighting Bcl-xL's role in early skin carcinogenesis through anti-apoptotic functions.

This study introduced Scd3-Cre mice, which enabled sebocyte-specific manipulation, revealing that sebaceous lipid depletion impaired water repulsion, thermoregulation, and the ocular surface, resembling Meibomian gland dysfunction.

This case report identified UVB photosensitivity and testicular failure as previously unreported components of low-sulfur hair syndrome in a 16-year-old male.

This study found that deleting the transcription factor Twist1 in keratinocytes significantly reduced UVB-induced skin carcinogenesis in mice, suggesting a potential target for preventing cutaneous squamous cell carcinoma.

In this study, 15d-PGJ2 administered in a topical cream inhibited oxidative and inflammatory skin changes caused by UVB radiation in hairless mice, suggesting it as a promising treatment approach.

A 12-year-old with ichthyosis linearis circumflexa showed significant improvement after 30 sessions of narrowband UVB phototherapy, as reported in this case study.

This study observed significant skin changes, including epidermal thickening and pleomorphic keratinocytes, in rats after subchronic UVB irradiation, highlighting specific reactions in the dorsal skin.

In this study using SKH-1 mice, researchers observed that acute UVB exposure increased expression of retinoid metabolism proteins and decreased retinol storage enzyme levels, suggesting enhanced retinoic acid synthesis in the epidermis.

This study found that cis-urocanic acid can engage in non-enzymatic reactions with reactive sulphur species, forming new metabolites, and suggests sulphide donors may protect against UVB-related toxicity.

This study found that Gynostemma pentaphyllum hydrodistillate and Damulin B exert significant anti-photoaging effects in UVB-irradiated models by reducing oxidative stress, improving ECM integrity, and enhancing skin hydration and elasticity.

This study found that UVB exposure led to visible tanning and distinct DNA methylation changes in pigmentation genes in tan-capable skin but not in non-tan skin, highlighting GNAS as a potentially UVB-responsive gene.

This study found that deleting the Twist1 gene in skin keratinocytes significantly reduced UVB-induced skin cancer and hyperproliferation in mice and suggested Twist1 as a target for skin cancer prevention.

This study found that combining UVB irradiation with anti-CD154 antibody improves the survival of hair follicle allografts in a humanized mouse model, suggesting a synergistic effect for allogeneic hair transplantation.

This study found that acute UVB exposure in mice increases the synthesis of retinoic acid in the epidermis, which is necessary for normal repair from UVB light.

This review updates the protective effects and molecular mechanisms of melatonin against ultraviolet-induced damage in human skin, reporting no new clinical findings.

This study developed a precise and reliable UV spectrophotometric method for determining finasteride concentration in bulk and tablets, demonstrating strong linearity and accuracy.

In this study involving children with alopecia areata, researchers found that adding narrowband UVB 311 nm therapy to standard treatment significantly improved hair regrowth in those with coexisting atopic dermatitis compared to those without the condition.

In this case report, narrowband-UVB phototherapy successfully treated a rare instance of Graham Little-Piccardi-Lassueur syndrome, a variant of lichen planopilaris, as investigated through non-invasive imaging techniques.

This study found that MF patients with darker skin types show slower initial improvement with NB-UVB phototherapy, highlighting disparities in treatment efficacy that warrant further investigation.

In this case report, a nine-year-old child with vitiligo and alopecia areata was successfully treated with upadacitinib and UVB, resulting in a significant reduction in the affected areas, suggesting a promising treatment approach for similar pediatric cases.

This study developed a highly sensitive fluorescent assay for measuring enzyme activity in single hair follicles, allowing the efficient analysis of over 100 samples per day.

This study developed and validated a simple, precise, and cost-effective UV spectrophotometric method for quantifying Minoxidil in bulk and pharmaceutical forms, reporting high accuracy with recovery rates between 99.57% and 100.55%, and a correlation coefficient of 0.9993.
