内体分选转运复合体(endosomalsortingcomplex required for transport,ESCRT)是细胞中一个复杂的系统,该系统在病毒感染中起着“双刃剑”的作用,即它们能够被不同家族病毒劫持用于自身增殖,也能被宿主细胞利用对抗病毒的侵染。在病毒生命周期的不同阶段,病毒可以通过多种方式利用或限制ESCRT系统介导的生理过程,或者直接调控ESCRT系统的各蛋白组分的表达增加感染宿主的能力。ESCRT是由20多种蛋白质组成的复合体。根据其成分及其功能差异可以分为若干个复合物,即ESCRT-0、ESCRT-Ⅰ、ESCRT-Ⅱ、ESCRT-Ⅲ.

Benefiting from the recent progress in precise engineering of quantum states and sub-10 mHz linewidth lasers,the stability and accuracy of optical atomic clocks have reached and even exceeded the 1018 level,surpassing their microwave counterparts by over two orders of magnitude[1,2].These advances lead to an anticipated redefinition of the international system of units(SI)second in terms of an optical reference transition as early as 2026.
