Phytomedicine, which uses plant-based compounds, is emerging as a promising approach to managing such inflammatory diseases. Limonin, a phytochemical found in citrus fruits and known for its bitter taste, possesses significant pharmacological properties. In this study, we evaluated the anti-psoriatic effects of limonin using a psoriasis-induced mice model. BALB/c mice were treated with imiquimod to induce psoriasis and then administered limonin at doses of 20 and 40 mg/kg/day for 6 days. Tacrolimus ointment served as a positive control. We assessed the hematological profile to determine limonin's impact on leukocytes in the psoriasis model. Additionally, histomorphometric analysis of ear and skin tissues was conducted to evaluate the therapeutic effects of limonin. We further investigated the antioxidant properties of limonin by measuring levels of antioxidants and oxidative stress markers. The anti-inflammatory effects were evaluated by quantifying inflammatory cytokines and signaling proteins. In vitro, the cytotoxicity and anti-inflammatory potential of limonin were assessed using murine macrophage RAW264.7 cells. Our findings showed that limonin significantly reduced leukocyte counts, decreased inflammatory cell infiltration, and improved skin histoarchitecture in psoriasis-induced mice. Limonin also effectively scavenged free radicals and reduced levels of inflammatory cytokines and proteins without causing cytotoxicity in RAW264.7 cells. Overall, our in vivo and in vitro results confirm that limonin is a potent anti-inflammatory agent that effectively ameliorates imiquimod-induced psoriasis.</p>","PeriodicalId":18876,"journal":{"name":"Naunyn-Schmiedeberg's archives of pharmacology","volume":" ","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142864678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This was supported by increased reactive oxygen species production, upregulation of pro-apoptotic genes, downregulation of anti-apoptotic genes, and elevated caspase 3 and 7 activity, collectively promoting apoptosis.

This study sheds light on the influence of persecution and expulsion of Jewish and dissident German pharmacologists during the Nazi era (1933-1945) on their scientific work and publication behaviour. The analysis is based on the German-language book 'Verfolgte deutschsprachige Pharmakologen (persecuted German-speaking pharmacologists) 1933-1945' by Trendelenburg and Löffelholz (2008), which contains short biographies of 71 persecuted pharmacologists. We analysed their publication activity from 1900 to 1980, the topics of the publications and the emigration data. Most persecuted pharmacologists emigrated, with two peaks of emigration around 1933 and 1938. Most pharmacologists emigrated to the USA, followed by Great Britain. Five of the scientists who emigrated to Great Britain were elected to the British Pharmacological Society's Pharmacology Hall of Fame, and one of them was a Nobel Laureate. Very few of the emigrated pharmacologists returned to Germany. After the Nazis came to power in 1933, the share of papers by persecuted pharmacologists in Naunyn-Schmiedeberg's Archives of Pharmacology dropped sharply. At around 1936, several of the persecuted pharmacologists began to publish increasingly in the American competitor journal, the Journal of Pharmacology and Experimental Therapeutics. The persecuted pharmacologists who emigrated to Great Britain had a major influence on the British Journal of Pharmacology, founded in 1946, as initially, they accounted for a high proportion of publications. We further analysed the papers published in Naunyn-Schmiedeberg's Archives of Pharmacology by persecuted pharmacologists between 1933 and 1945. About half of these papers were submitted from abroad, indicating that despite the persecution and repression, papers from persecuted pharmacologists previously working at German institutes were still published during this period. Most of the papers by persecuted pharmacologists published from German institutes during this period were published under regime-critical or politically persecuted institute directors. Persecuted pharmacologists covered a huge spectrum of scientific topics, highlighting their immense scientific impact. After World War II, Naunyn-Schmiedeberg's Archives of Pharmacology lost much of its previous thematic diversity for decades. Overall, our analyses highlight the enormous loss to German pharmacology due to the persecution, exclusion and expulsion of 'non-Aryan' pharmacologists.
