DNA nanodevices to control cell movement
Mechanical Modulation of Cell Migrations by DNA Nanoassemblies
Tiny DNA-built springs are used to change how cells move, aiming to help people with diseases where cell movement is abnormal, such as some autoimmune conditions.

What this research studies
This project builds tiny DNA origami 'nanosprings' that can push or pull on cell surface receptors involved in movement. The team will measure the springs' stiffness with optical tweezers and read their stretch using fluorescent dye pairs (FRET) to estimate forces at the nanoscale. They will place these nanosprings at cell membranes to alter clustering of integrin receptors and observe how that changes cell migration. Results come from laboratory experiments on cells using these engineered DNA assemblies to probe and modify mechanical signals that guide cell motion.
Who could benefit from this research
Good fit: People with conditions linked to abnormal cell migration or adhesion, like some autoimmune diseases, would be the most relevant patient group for future translation of this work.
Not a fit: Patients needing immediate clinical treatments or whose illness is unrelated to cell migration mechanics are unlikely to gain direct benefit from this basic laboratory research.
Why it matters
Potential benefit: If successful, this work could open new ways to control harmful cell movement in diseases such as certain autoimmune disorders or cancer.
How similar studies have performed: Related nanoscale force-sensing techniques exist, but using DNA nanosprings to actively control integrin clustering and cell migration is largely novel and untested in patients.
