摘要
背景:银屑病是一种慢性皮肤病,与持续的炎症和皮损有关。通过使用抗炎药物,外用疗法一直是缓解银屑病的有效方法。试验表明,磷脂酰丝氨酸(PS)具有抗炎作用。因此,本研究旨在评估外用 PS 对改善咪喹莫特(IMQ)诱导的银屑病模型的潜在影响。此外,我们还使用环孢素 A 作为抗银屑病的对比药物:牛皮癣模型的建立是通过在小鼠背侧皮肤上局部涂抹 IMQ,每天一次,连续五天。使用银屑病面积和严重程度指数(PASI)来评估外用 PS 的疗效。随后,使用贝克评分系统、马森三色染色法、免疫组化法和实时 PCR 分析法对皮肤样本进行分析:结果:IMQ诱导的斑块型银屑病导致皮损部位的真皮厚度、角化过度、PASI评分和炎症细胞因子显著增加(P)。与未经处理的小鼠相比,外用 PS 和环孢素 A 能显著降低 PASI 评分和真皮厚度,同时还能减轻红斑和鳞屑。此外,生物分子评估显示,PS 能明显抑制 IMQ 诱导的皮损中 IL-17、IL-23 和 TNF-α 细胞因子的基因表达:结论:外用 PS 可通过抑制炎症明显缓解银屑病。结论:外用 PS 可通过抑制炎症显著缓解银屑病,建议在控制皮肤银屑病的实验和临床研究中进一步探讨 PS 的有益作用。
Phosphatidylserine Topically Attenuates Imiquimod-induced Psoriasis Through Inflammation Inhibition in Mice.
Background: Psoriasis is a chronic skin condition that is associated with persistent inflammation and skin lesions. Topical therapy has been a promising approach to the alleviation of psoriasis through the application of anti-inflammatory agents. Phosphatidylserine (PS) administration has shown anti-inflammatory effects in the trials. Consequently, the objective of this study was to evaluate the effects of topical PS on the potential improvement of an imiquimod (IMQ)-induced psoriasis model. Additionally, cyclosporine A was utilized as a comparative anti-psoriatic agent in our study.
Methods: The psoriasis model was established by topically applying IMQ to the dorsal skin of mice once daily for five consecutive days. The efficacy of topical PS was assessed using the Psoriasis Area and Severity Index (PASI) score to evaluate skin lesions. Subsequently, the skin samples were analyzed using Baker's scoring system, Masson's trichrome staining, immunohistochemistry, and real-time PCR analysis.
Results: IMQ-induced plaque-type psoriasis resulted in a significant increase (P<0.05) in dermal thickness, hyperkeratosis, PASI score, and inflammatory cytokines at the lesion site. The topical PS and cyclosporine A significantly (P<0.05) reduced PASI score and dermal thickness, while also alleviating erythema and scaling when compared to untreated mice. Furthermore, biomolecular assessments revealed that PS significantly (P<0.05) inhibited the gene expression of IL-17, IL-23, and TNF-α cytokines in the IMQ-induced lesions.
Conclusion: Topical PS may pointedly alleviate psoriasis through the inhibition of inflammation. The beneficial effects of the PS recommend further investigation in both experimental and clinical studies in the control of skin psoriasis.
期刊介绍:
Drug Research (formerly Arzneimittelforschung) is an international peer-reviewed journal with expedited processing times presenting the very latest research results related to novel and established drug molecules and the evaluation of new drug development. A key focus of the publication is translational medicine and the application of biological discoveries in the development of drugs for use in the clinical environment. Articles and experimental data from across the field of drug research address not only the issue of drug discovery, but also the mathematical and statistical methods for evaluating results from industrial investigations and clinical trials. Publishing twelve times a year, Drug Research includes original research articles as well as reviews, commentaries and short communications in the following areas: analytics applied to clinical trials chemistry and biochemistry clinical and experimental pharmacology drug interactions efficacy testing pharmacodynamics pharmacokinetics teratology toxicology.
