How-ever, the causal relationship between atopic dermatitis and psychiatric disorders remains unclear. This study employed bidirectional 2-sample Mendelian randomization to investigate the potential causal relationships between atopic dermatitis and 8 psychiatric conditions: depression, anxiety, autism spectrum disorder, attention deficit hyperactivity disorder, suicidality, bipolar disorder, obsessive-compulsive disorder, and schizophrenia. Genetic instruments were derived from large-scale genome-wide association studies of European ancestry. Forward Mendelian randomization analysis indicated that atopic dermatitis causally increases the risk of anxiety (inverse variance weighting p = 0.016; odds ratio = 1.110, 95% confidence interval: 1.019-1.208). Reverse Mendelian randomization analysis revealed a significant causal effect of bipolar disorder on increasing the risk of atopic dermatitis (inverse variance weighting p = 0.005; odds ratio = 1.062, 95% confidence interval: 1.018-1.107). No significant causal relationships were found for other psychiatric conditions. Sensitivity analyses confirmed the robustness of these findings, with no evidence of horizontal pleiotropy. These results highlight the need for integrated dermatological and psychiatric care, emphasizing early mental health screening for atopic dermatitis patients and dermatological evaluation for individuals with bipolar disorder. Future research should explore underlying biological mechanisms and validate findings across diverse populations.</p>","PeriodicalId":6944,"journal":{"name":"Acta dermato-venereologica","volume":"105 ","pages":"adv43133"},"PeriodicalIF":3.5,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12105540/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144075288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While several wavelengths of LEDs have been reported to inhibit melanin production by targeting melanin synthesis-related enzymes, melanosomes, and paracrine factors stimulating melanogenesis from keratinocytes, the effects of green LED (GLED) remain largely unexplored. This study aimed to investigate the effects of GLED on cell viability, melanin production, and melanin-related gene expression using B16 melanoma cells and 3-dimensional (3D) skin models. Furthermore, its efficacy in improving skin pigmentation was evaluated through a human intervention study with GLED-equipped facial masks. The melanin synthesis inhibitory effects of 505 nm GLED were evaluated using B16 mouse melanoma cells, a 3D skin model containing melanocytes, and a human intervention study with 505 nm GLED-equipped masks. 505 nm GLED irradiation reduced melanin production in melanogenesis-induced B16 mouse melanoma cells by suppressing the gene expression levels of microphthalmia-associated transcription factor and tyrosinase. Furthermore, GLED irradiation also reduced melanin content in 3D skin models without affecting cell viability. Finally, a human intervention study demonstrated that GLED irradiation on human facial skin effectively decrease pigmentation.
