Abstract
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.
