报道了氯喹(CQ)对人冠状病毒229E (HCoV-229E)感染人胎儿肺细胞株L132的抗病毒作用。CQ显著降低了低于临床使用浓度的病毒复制。我们证明了CQ影响p38丝裂原活化蛋白激酶(MAPK)和细胞外信号调节激酶(ERK)的激活。此外,p38 MAPK抑制剂SB203580抑制HCoV-229E感染和病毒复制诱导的CPE。我们的研究结果表明,CQ影响参与HCoV-229E复制的MAPKs的激活。
The antiviral effects of chloroquine (CQ) on human coronavirus 229E (HCoV-229E) infection of human fetal lung cell line, L132 are reported. CQ significantly decreased the viral replication at concentrations lower than in clinical usage. We demonstrated that CQ affects the activation of p38 mitogen-activated protein kinase (MAPK) and extracellular signal-regulated kinase (ERK). Furthermore, p38 MAPK inhibitor, SB203580, inhibits CPE induced by HCoV-229E infection and viral replication. Our findings suggest that CQ affects the activation of MAPKs, involved in the replication of HCoV-229E.
