Inhibiting ACSL1-Related Ferroptosis Restrains Murine Coronavirus Infection #MMPMID34960652Xia H; Zhang Z; You FViruses 2021[Nov]; 13 (12): � PMID34960652show ga
Murine hepatitis virus strain A59 (MHV-A59) was shown to induce pyroptosis, apoptosis, and necroptosis of infected cells, especially in the murine macrophages. However, whether ferroptosis, a recently identified form of lytic cell death, was involved in the pathogenicity of MHV-A59 is unknown. We utilized murine macrophages and a C57BL/6 mice intranasal infection model to address this. In primary macrophages, the ferroptosis inhibitor inhibited viral propagation, inflammatory cytokines released, and cell syncytia formed after MHV-A59 infection. In the mouse model, we found that in vivo administration of liproxstatin-1 ameliorated lung inflammation and tissue injuries caused by MHV-A59 infection. To find how MHV-A59 infection influenced the expression of ferroptosis-related genes, we performed RNA-seq in primary macrophages and found that MHV-A59 infection upregulates the expression of the acyl-CoA synthetase long-chain family member 1 (ACSL1), a novel ferroptosis inducer. Using ferroptosis inhibitors and a TLR4 inhibitor, we showed that MHV-A59 resulted in the NF-kB-dependent, TLR4-independent ACSL1 upregulation. Accordingly, ACSL1 inhibitor Triacsin C suppressed MHV-A59-infection-induced syncytia formation and viral propagation in primary macrophages. Collectively, our study indicates that ferroptosis inhibition protects hosts from MHV-A59 infection. Targeting ferroptosis may serve as a potential treatment approach for dealing with hyper-inflammation induced by coronavirus infection.|*Ferroptosis[MESH]|Animals[MESH]|Coenzyme A Ligases/*antagonists & inhibitors/genetics/*metabolism[MESH]|Coronavirus Infections/*therapy[MESH]|Cytokines/metabolism[MESH]|Disease Models, Animal[MESH]|Genes, Viral[MESH]|Lung Injury/pathology[MESH]|Macrophages[MESH]|Mice[MESH]|Mice, Inbred C57BL[MESH]|Murine hepatitis virus[MESH]|Quinoxalines[MESH]|RAW 264.7 Cells[MESH]|Spiro Compounds[MESH]|Toll-Like Receptor 4[MESH]
