Ep53: Microbubble Technology and Focused Ultrasound: A Conversation with Sasha Klibanov, PhD
Targeted drug delivery to the brain has long been hindered by the blood-brain barrier, a protective layer that prevents many therapeutic agents from reaching their intended targets. For patients with serious neurological disorders, this challenge can significantly reduce access to potentially effective treatments and limit therapeutic outcomes.
In this episode of Curing with Sound, we speak with Sasha Klibanov, PhD, Associate Professor in the Division of Cardiovascular Medicine at the University of Virginia and a pioneering researcher in microbubble technology. Dr. Klibanov discusses the evolution of microbubbles from imaging contrast agents to sophisticated tools for drug delivery. He also explains how focused ultrasound, combined with microbubbles, can safely and temporarily open the blood-brain barrier, creating new opportunities for precision therapies and advancing the potential of immunotherapy.
Discussion highlights:
- Microbubble Technology Explained: Explore how microbubbles evolved from diagnostic imaging tools into powerful agents for precise drug delivery when combined with focused ultrasound.
- Advancing Immunotherapy: Learn about Dr. Klibanov's collaborative research on using size-sorted microbubbles to optimize the opening of the blood-brain barrier, potentially revolutionizing how we treat complex diseases by enabling targeted immune responses.
