Cavitation-induced cellular effects

Cavitation-induced cellular effects are mechanical and biochemical changes triggered in biological tissues when exposed to inertial or stable cavitation, often via ultrasound or other mechanical forces. These include increased cell membrane permeability, induction of cellular death, and modulation of cellular signaling pathways. Stable cavitation can create reversible pores in cell membranes and enhance drug or gene delivery (sonoporation), while inertial cavitation (violent bubble collapse) can cause irreversible cell damage and tissue destruction (histotripsy)[2][3][6]. These effects are being leveraged for therapeutic purposes including targeted cancer treatment, transient blood-brain barrier opening, and enhanced delivery of drugs or genes. Cavitation-induced cellular effects do not represent a single molecular target, but rather a class of physical mechanisms and their associated cellular outcomes. It is thus not a canonical molecular target suitable for direct drug binding or classic pharmacological manipulation, but instead a therapeutic approach utilizing physical bioeffects[2][3][6][8]. Note: This entry describes a physical process and its cellular outcomes, not a molecule, receptor, enzyme, or transporter. Accordingly, it is considered incorrect as a canonical therapeutic target. If you need information on specific molecules affected by or mediating cavitation-induced effects (such as membrane proteins implicated in sonoporation), please clarify your query.
