Programmable and Switchable RNA Scaffolds for Synthetic Condensate Engineering in Mammalian Cells

2026

Objective: Engineer programmable and switchable RNA scaffolds for synthetic condensate formation in mammalian cells.

Why it works: The source scaffold indicates that nanostar-derived RNA scaffolds can be expressed in mammalian cells and that condensate formation depends on dsRNA-stem-driven assembly, while an acyclovir-responsive switch adds external control.
