Sono-Mechanogenetics: Linking Ultrasound Physics With Cellular Mechanobiology

Area of Science:

• Biophysics
• Cellular Mechanobiology
• Biotechnology

Background:

• Sono-mechanogenetics couples focused ultrasound with genetic responses via mechanotransduction.
• Current progress often treats ultrasound as a black box and mechanosensitive elements as isolated sensors.

Purpose of the Study:

• To reframe sono-mechanogenetics by integrating ultrasound physics and cellular mechanobiology.
• To provide a mechanistic understanding for rational design of future systems.

Main Methods:

• Review of ultrasound physics, focusing on mechanical energy delivery and deformation modes.
• Analysis of cellular mechanotransduction pathways (ECM, membrane, cytoskeleton, nucleus).
• Examination of applications in neural modulation and immunotherapy through a mechanical perturbation lens.

Main Results:

• Ultrasound delivers programmable mechanical energy that interacts with cellular force-sensing networks.
• Mechanotransduction pathways naturally sense, integrate, and transduce mechanical information.
• Mechanobiological principles can guide the design of advanced sono-mechanogenetic tools.

Conclusions:

• Moving beyond empirical activation towards mechanistically informed and predictive control in sono-mechanogenetics.
• Understanding the interplay between ultrasound physics and cellular mechanobiology is crucial.
• This approach facilitates the rational design of next-generation sono-mechanogenetic systems.
