Design of a Membrane-Anchored DNAzyme-Based Molecular Machine for Enhanced Cancer Therapy by Customized Cascade Regulation

Synthetic DNAzyme-based structures enable dynamic cell regulation. However, engineering an effective and targeted DNAzyme-based structure to perform customizable multistep regulation remains largely unexplored. Herein, we designed a membrane-anchored DNAzyme-based molecular machine to implement dynamic inter- and intracellular cascade regulation, which realizes efficient T-cell/cancer cell interactions and subsequent receptor mediated cancer cell uptake.
