In this study, we examined the immunomodulatory properties of orally administered triptolide, a major diterpenoid triepoxide disjunct from a twining vine Tripterygium wilfordii. SJL/J mice were ready with PLP139151 peptid e and orally treated with triptolide (100 ?g/kg per day) from the day of EAE induction (preventive regime) and after the onset of clinical signs (therapeutic regime). Triptolide delayed disease onset, trim down clinical symptoms, slump the relapse rate, and suppressed in?ammation and demyelination in CNS thread paper of EAE mice when compared to vehicle-treated animals. Molecular analysis revealed a pronounced increase of change shock protein 70 (Hsp70) mRNA and protein in the CNS tissue of triptolide-treated animals. Cytokine and chemokine expression analysis from EAE tissues and in vitro macrophages observe a decrease of key pro-in?ammatory mRNAs. Triptolide inhibited I?B? phosphorylation and NF-?B thermonuclear translocation by stabilization of NF-?B/I?B? complex, possibly due to a direct animal(prenominal) interaction between NF-?B and Hsp70 proteins. Lymph node cell proliferation hindrance in EAE con?rmed the immunosuppressant ef?cacy of triptolide.
