1 型单纯疱疹病毒 (HSV-1) 感染会导致严重的病情,并伴有严重的并发症,包括因眼部感染不受控制而导致的角膜失明。针对 HSV-1 感染的重要细胞防御机制是自噬。宿主细胞的自噬反应被认为是受HSV-1调节的。在这项研究中,我们对多种 HSV-1 靶向细胞类型以及各种感染条件下的自噬进行了详细分析,以概括高效的感染模型。我们发现,在一种细胞类型中,自噬受到轻微抑制,而在其他细胞类型中,自噬在生产性感染期间基本保持基本水平不变。这项研究完善了 HSV-1 介导的自噬调节的概念,意味着抑制或预防先天免疫途径的激活。
Herpes simplex virus-1 (HSV-1) infection causes severe conditions, with serious complications, including corneal blindness from uncontrolled ocular infections. An important cellular defense mechanism against HSV-1 infection is autophagy. The autophagic response of the host cell was suggested to be regulated by HSV-1. In this study, we performed a detailed analysis of autophagy in multiple HSV-1-targeted cell types, and under various infection conditions that recapitulate a productive infection model. We found that autophagy was slightly inhibited in one cell type, while in other cell types autophagy maintained its basal levels mostly unchanged during productive infection. This study refines the concept of HSV-1-mediated autophagy regulation to imply either inhibition, or prevention of activation, of the innate immune pathway.
