在这项研究中,我们研究了自噬和凋亡在新城疫病毒(NDV)感染的鸡细胞和组织中的作用。透射电镜显示,ndv感染和饥饿诱导的鸡胚成纤维细胞(CEF)细胞比模拟感染的CEF细胞具有更高的自噬体形成。ndv感染的CEF细胞显示微管相关蛋白1轻链3-I (LC3-I)向LC3-II的转化增强,p62/SQSTM1降解增强。在紫外线灭活的NDV感染细胞中,LC3-I到LC3-II的转化以及裂解的caspase 3和聚adp核糖聚合酶(PARP)的减少表明自噬体的形成是NDV复制所必需的。氯喹(chloroquine, CQ)抑制自噬可增强细胞凋亡,导致caspase 3和PARP的切割增加,AnnexinV/碘化丙啶染色增加。雷帕霉素诱导自噬可导致ndv感染的脾和肺组织中除Beclin 1、抗凋亡因子和促炎因子外的所有自噬相关基因上调。随后,ndvv感染的脾脏和肺部的细胞凋亡比模拟感染的器官减少。泛caspase抑制剂zad - fmk通过抑制凋亡促进LC3-I向LC3-II的转化、p62/SQSTM1的降解、NDV复制和细胞活力。我们的研究表明,抑制细胞凋亡可增强细胞自噬,促进细胞存活和NDV复制。
In this study, we investigated the role of autophagy and apoptosis in Newcastle disease virus (NDV)-infected chicken cells and tissues. NDV-infected and starvation-induced chick embryo fibroblasts (CEF) cells showed higher autophagosome formation than mock-infected CEF cells on transmission electron microscopy. The NDV-infected CEF cells showed enhanced conversion of microtubule-associated protein 1 light chain 3-I (LC3-I) to LC3-II and degradation of p62/SQSTM1. The diminished conversion of LC3-I to LC3-II and cleaved caspase 3 and poly (ADP-ribose) polymerase (PARP) in ultraviolet-inactivated NDV-infected cells suggested that autophagosome formation was necessary for NDV replication. Inhibition of autophagy by chloroquine (CQ) enhanced apoptosis resulting in increased cleavage of caspase 3 and PARP and AnnexinV/propidium iodide staining. Autophagy induction by rapamycin resulted in upregulation of all autophagy-related genes except Beclin 1, anti-apoptosis factors, and proinflammatory cytokines in the NDV-infected spleen and lung tissues. Subsequently, decreased apoptosis was observed in NDV-infected spleens and lungs than mock-infected organs. The pan-caspase inhibitor ZVAD-FMK promoted conversion of LC3-I to LC3-II, the degradation of p62/SQSTM1, NDV replication and cell viability by inhibiting apoptosis. Our study demonstrates that apoptosis inhibition enhances autophagy and promoted cell survival and NDV replication.
