Ultrasound and Sonogenetics: A New Perspective for Controlling Cells with Sound

An important challenge in neurobiology is to stimulate a single neuron, especially in deep areas of the brain. The optogenetics methods need a surgical operation to convey light sources to targeted cells. Nowadays, non-invasive tools such as sonogenetics with the ability to modulate and visualizing cellular and molecular processes have attracted much attention. The study of the biological functions of living organisms always requires tools for monitoring and imaging dynamically. Current sonogenetic approaches use ultrasound as a non-invasive tool to precisely control cellular function. In general, sonogenetics includes the development of mechano-sensitive proteins, approaches for introducing their genes to specific cells, targeted stimulation, and finally, reading the outcome. Hence, to prepare a short review of emerging technology sonogenetics, we summarized the introduction of sound waves, the mechano-sensitive proteins commonly used in sonogenetics, and potential therapeutic applications of sonogenetics for biological research and medicine. This short review would beneficiate in the translation of sonogenetics from present in-vitro and in-vivo investigations to clinical therapies.
