Acyclovir (ACV) and its derivatives have been highly effective for treating recurrent, lytic infections with Herpes Simplex Virus, type 1 (HSV-1), but searches for additional antiviral drugs are motivated by recent reports of resistance to ACV, particularly among immunocompromised patients. In addition, the relative neurotoxicity of ACV and its inability to prevent neurological sequelae among HSV-1 encephalitis survivors compel searches for new drugs to treat HSV-1 infections of the central nervous system (CNS). Primary drug screens for neurotropic viruses like HSV-1 typically utilize non-neuronal cell lines, but they may miss drugs that have neuron specific antiviral effects. Therefore, we compared the effects of a panel of conventional and novel anti-herpetic compounds in monkey epithelial (Vero) cells, human induced pluripotent stem cells (hiPSCs)-derived neural progenitor cells (NPCs) and hiPSC-derived neurons (N = 73 drugs). While the profiles of activity for the majority of the drugs were similar in all three tissues, Vero cells were less likely than NPCs to identify drugs with substantial inhibitory activity in hiPSC-derived neurons. We discuss the relative merits of each cell type for antiviral drug screens against neuronal infections with HSV-1.
阿昔洛韦(ACV)及其衍生物在治疗单纯疱疹病毒1型(HSV-1)的复发性溶细胞感染方面一直非常有效,但由于最近有对ACV耐药的报道,尤其是在免疫功能低下的患者中,因此人们开始寻找其他抗病毒药物。此外,ACV的相对神经毒性以及它无法预防HSV-1脑炎幸存者的神经后遗症,促使人们寻找治疗中枢神经系统(CNS)HSV-1感染的新药。针对HSV-1等嗜神经病毒的主要药物筛选通常使用非神经元细胞系,但可能会遗漏具有神经元特异性抗病毒作用的药物。因此,我们比较了一组传统和新型抗疱疹化合物在猴上皮(Vero)细胞、人诱导多能干细胞(hiPSC)衍生的神经祖细胞(NPC)和hiPSC衍生的神经元中的作用(共73种药物)。虽然大多数药物在所有三种组织中的活性谱相似,但与NPC相比,Vero细胞识别在hiPSC衍生神经元中具有显著抑制活性药物的可能性较小。我们讨论了每种细胞类型在针对HSV-1神经元感染的抗病毒药物筛选中的相对优点。
