Amphisomes are preautolysosomal vacuoles formed upon the fusion of autophagosomes with endosomes, and as such represent a critical meeting point between endocytic and autophagic pathways. Dengue virus enters into susceptible cells by clathrin-mediated endocytosis, and colocalization of dengue markers with markers of both autophagic and endosomal vesicles demonstrates that amphisomes are a site of dengue virus replication and translation. This work links for the first time the processes of dengue virus entry and translation/replication, and allows for interpretation of the early part of the dengue virus life cycle in terms of a continual association with membranes of an endosomal-autophagosomal lineage.
自噬溶酶体前体泡是自噬体与内体融合后形成的,因此代表了内吞途径和自噬途径的关键交汇点。登革病毒通过网格蛋白介导的内吞作用进入易感细胞,登革病毒标志物与自噬和内体小泡标志物的共定位表明,自噬溶酶体前体泡是登革病毒复制和翻译的场所。这项工作首次将登革病毒的进入过程与翻译/复制过程联系起来,并使得能够根据与内体-自噬体谱系膜的持续关联来解释登革病毒生命周期的早期阶段。
