Abstract:

The specific interaction between receptor and ligand on cell surface plays an important role in cell biology. However, the distribution of receptor molecules on the cell membrane is discontinuous and dynamically different from that in the homogeneous solutions. The receptor-ligand interactions on the cell surface usually exhibit complex nonlinear binding patterns. In order to reveal the mechanisms, framework nucleic acids, as a class of DNA nanostructures with definite geometric shapes, could be used for the coupling of multivalent ligands. With the addressability at nanoscale, the number, spacing and spatial conformation of ligands are precisely regulated on framework nucleic acids. The binding characteristics between receptor and ligand on cell surface are studied, and efficient molecular recognition and targeted therapy could be achieved by optimizing these influencing factors. In this paper, the research progress of receptor-ligand interactions on cell surface based on framework nucleic acids is reviewed. By discussing the important influencing factors and biological applications, the future development of receptor-ligand interactions on cell surface based on framework nucleic acids is prospected.
