LARP7 upregulates SIRT1 deacetylase activity and inhibits Th1/Th17 cytokine response in psoriatic mice.
Objective: To investigate the possible role of La ribonucleoprotein 7 (LARP7) in psoriasis through a mouse model and uncover its underlying mechanism.
Methods: The back skin of C57BL/6 mice was smeared with IMquimod (IMQ) cream for 7 days to induce psoriasis. Immunoblot kit was used to detect the deacetylase activity of SIRT1 (member of sirtuin family). Hematoxylin and eosin staining was used to assess the degree of psoriasis in mouse. Flow cytometry assays were performed to confirm effects on Th1/Th17 cell differentiation. Enzyme-linked-immunosorbent serologic assays were used to detect the level of secreted cytokines.
Results: LARP7 upregulated SIRT1 deacetylase activity. LARP7 alleviated psoriasis symptoms in mice by upregulating SIRT1 deacetylase activity. In addition, LARP7 regulated Th1/Th17 cell differentiation in psoriatic mice. We further found that LARP7 inhibited Th1/Th17 cytokine.
Conclusion: LARP7 upregulated SIRT1 activity and inhibited Th1/Th17 cytokine response in psoriatic mice.
期刊介绍:
Founded in 1972 by Professor A. Oehling, Allergologia et Immunopathologia is a forum for those working in the field of pediatric asthma, allergy and immunology. Manuscripts related to clinical, epidemiological and experimental allergy and immunopathology related to childhood will be considered for publication. Allergologia et Immunopathologia is the official journal of the Spanish Society of Pediatric Allergy and Clinical Immunology (SEICAP) and also of the Latin American Society of Immunodeficiencies (LASID). It has and independent international Editorial Committee which submits received papers for peer-reviewing by international experts. The journal accepts original and review articles from all over the world, together with consensus statements from the aforementioned societies. Occasionally, the opinion of an expert on a burning topic is published in the "Point of View" section. Letters to the Editor on previously published papers are welcomed. Allergologia et Immunopathologia publishes 6 issues per year and is included in the major databases such as Pubmed, Scopus, Web of Knowledge, etc.
