摘要
The building and engineering of an artificial molecular signaling svstem in encapsulated vesicles is a keystep towards artificial cells.Recently.Tan et al.reached a new milestone by integrating an intelligent DNA nanogatekeeper with an artificial vesicle system.The DNA nanogatekeeper driven by adenosine triphosphate(AIP)is able to receive outside stimulus.which in turn switches the diffusion of environmental ions into the integrated vesicle.Most importantly,this system enables triggering downstream signaling cascaded reactions confined in the artificial vesicle,as well as returning feedback to the DNA nanogatekeeper.mimicking real cellular behaviors of reception.transduction and response.This work has been published online in Nature Communications on February 20,2020。
