CARIBBBOU

Project Description

It has been recognized that the blood brain barrier (BBB) presents a major obstacle to the entry of therapeutic molecules into the central nervous system (CNS). It has been shown that, using ultrasound with the presence of microbubbles to locally enhance acoustic cavitation in CNS capillaries, the CNS-blood permeability can be significantly increased due to the temporal opening of the BBB, thus providing a promising strategy to increase delivery of therapeutic agents into brain tumors. Understanding the mechanisms underlying molecular uptake stimulation and ultrasound-based cell modification in brain tissue is crucial, with the key requirement of a better control of the various aspects of cavitation phenomenon.

The CARIBBBOU project is an international consortium whose aim is to focus on the in-vitro and in-vivo control of any kind of ultrasound cavitation activity, with application to the enhancement of BBB opening and brain gene delivery for CNS neurodegenerative diseases. This project is funded by the French National Research Agency (ANR) in combination to the Ministry of Science and Technology (MOST) in Taiwan, for a grant of 750 k€. The french PI is Claude Inserra (LabTAU) and taiwanese PI is Dr When-Shiang Chen (NTUH, Taiwan).
