Alteration of Essential Cell Function by Ultrasound-Targeted Microbubble Cavitation.

Area of Science:

• Biomedical Engineering
• Cell Biology
• Acoustic Medicine

Background:

• Ultrasound-targeted microbubble cavitation (UTMC) is a promising non-invasive technology for medical applications.
• Clinical translation of UTMC necessitates a thorough understanding of its cellular bioeffects.

Purpose of the Study:

• To review the mechanisms and cellular bioeffects of ultrasound-targeted microbubble cavitation.
• To explore the impact of UTMC on fundamental cellular processes relevant to its clinical applications.

Main Methods:

• Literature review of recent studies on UTMC.
• Analysis of molecular and cellular responses to UTMC.

Main Results:

• UTMC induces sonoporation, calcium ion influx, free radical generation, and nitric oxide synthesis.
• Observed effects include cytoskeletal remodeling, gene expression changes, and neuroinflammation.
• Cavitation mechanisms and their bioeffects on cellular function were examined.

Conclusions:

• UTMC significantly impacts cellular functions through various molecular mechanisms.
• Further research into these bioeffects will facilitate the clinical translation of UTMC.
