Parkin activation
WebRotenone, a component of pesticides, is widely used in agriculture and potentially causes Parkinson's disease (PD). However, the regulatory mechanisms of rotenone-induced PD are unclear. Here, we revealed a novel feedback mechanism of p38-Parkin-ROS regulating rotenone-induced PD. Rotenone treatment led to not only the activation of p38 but also … WebTBK1 can activate the synthesis of IFN regulatory factor (IRF)-3 and type I IFN, 94 and the autophosphorylation of TBK1 is an important step for mitophagy upon the ubiquitination of mitochondrial fragments. 95 In addition, the phosphorylation of optineurin (OPTN) by TBK1 promotes the binding efficiency of OPTN to ubiquitin (Ub) chains, which enhances …
