虽然大多数疾病缓解药物(DMD)通过抑制炎症来调节多发性硬化症(MS),但它们可能会抑制抗病毒免疫,导致进行性多灶性白质脑病(PML)。DMD醋酸格拉替雷(GA)已用于PML高风险的MS患者。我们通过使用Theiler小鼠脑脊髓炎病毒(TMEV)感染诱导的MS模型,研究GA用于病毒感染是否安全。用GA治疗TMEV感染的小鼠既不增强病毒载量也不抑制抗病毒免疫应答,但它导致Foxp 3/Il 17 a比率和IL-4/IL-10产生增加。这是第一项研究表明GA对已证实病毒感染的MS患者是安全的。
While most disease-modifying drugs (DMDs) regulate multiple sclerosis (MS) by suppressing inflammation, they can potentially suppress antiviral immunity, causing progressive multifocal leukoencephalopathy (PML). The DMD glatiramer acetate (GA) has been used for MS patients who are at high risk of PML. We investigated whether GA is safe for use in viral infections by using a model of MS induced by infection with Theiler’s murine encephalomyelitis virus (TMEV). Treatment of TMEV-infected mice with GA neither enhanced viral loads nor suppressed antiviral immune responses, while it resulted in an increase in the Foxp3/Il17a ratio and IL-4/IL-10 production. This is the first study to suggest that GA could be safe for MS patients with a proven viral infection.
