Dichapetalin-type triterpenoids inhibits macrophage interferon expression by regulating the cGas-STING pathway, suggesting potential application in immunosuppression.
Background: Dichapetalin-type triterpenoids (DTs) derived from Dichapetalum longipetalum (Turcz.) Engl. have attracted extensive attention due to their novel structure, as well as potent anti-tumor and anti-inflammatory activities. In this study, the immunosuppressive effect of Dichapetalin-type triterpenoids on mouse peritoneal macrophages (MPMs) was studied.
Methods: MPMs were stimulated with HSV-1 or LPS for the inflammation model. The cytokines and inflammatory mediators were detected by RT-PCR. Western blotting was carried out to determine the phosphorylation of TBK1 and IRF3.
Results: Our results showed that DTs inhibited the expression of IFN-β in MPMs infected with HSV-1, and also inhibited the expression of Il-1β and Il-6 in LPS-stimulated MPMs. In addition, compound 1 (dichapetalin A) down regulated the phosphorylation of Tbk1 and Irf3 in HSV-1-infected MPMs.
Conclusion: Taken together, this study suggests that DTs isolated from the Dichapetalum longipetalum (Turcz.) Engl. inhibits macrophage activation through the cGas-STING pathway in MPMs, which would be potential for the treatment of autoimmune diseases.
期刊介绍:
The journal Immunopharmacology and Immunotoxicology is devoted to pre-clinical and clinical drug discovery and development targeting the immune system. Research related to the immunoregulatory effects of various compounds, including small-molecule drugs and biologics, on immunocompetent cells and immune responses, as well as the immunotoxicity exerted by xenobiotics and drugs. Only research that describe the mechanisms of specific compounds (not extracts) is of interest to the journal.
The journal will prioritise preclinical and clinical studies on immunotherapy of disorders such as chronic inflammation, allergy, autoimmunity, cancer etc. The effects of small-drugs, vaccines and biologics against central immunological targets as well as cell-based therapy, including dendritic cell therapy, T cell adoptive transfer and stem cell therapy, are topics of particular interest. Publications pointing towards potential new drug targets within the immune system or novel technology for immunopharmacological drug development are also welcome.
With an immunoscience focus on drug development, immunotherapy and toxicology, the journal will cover areas such as infection, allergy, inflammation, tumor immunology, degenerative disorders, immunodeficiencies, neurology, atherosclerosis and more.
Immunopharmacology and Immunotoxicology will accept original manuscripts, brief communications, commentaries, mini-reviews, reviews, clinical trials and clinical cases, on the condition that the results reported are based on original, clinical, or basic research that has not been published elsewhere in any journal in any language (except in abstract form relating to paper communicated to scientific meetings and symposiums).
