Artesunate Attenuates Pro-Inflammatory Cytokine Release from Macrophages by Inhibiting TLR4-Mediated Autophagic Activation via the TRAF6-Beclin1-PI3KC3 Pathway

Abstract

AS inhibited LPS-induced cytokine release from macrophages by inhibiting autophagic activation. This effect was tightly related to blockade of the TRAF6-Beclin1-PI3KC3 pathway via decreasing K63-linked ubiquitination of Beclin1 and then interrupting the formation of Beclin1-PI3KC3 core complex of the PI3K-III complex. Our findings reveal the mechanism of AS's anti-inflammatory effect and is significant for future targeted investigations of sepsis treatment.
