Precise antibody delivery to the brain via nanobubble-actuated focused ultrasound alleviates depression.

ABSTRACT: Precise, noninvasive drug delivery to small but important brain regions is challenging and highly desired given the brain's inherent complexity and heterogeneous nature. Here, we report an approach utilizing focused ultrasound (FUS) combined with nanobubbles to successfully navigate this challenge. Compared to traditional microbubbles, nanobubbles exhibit superior acoustic properties. The nanobubbles, when exposed to FUS, induce a highly localized and reversible opening of the blood-brain barrier (BBB) with significantly enhanced precision (up to fourfolds compared to microbubbles, as measured by the precision loss metric). Repeated multitarget FUS-NB precisely delivers macromolecular human-derived anti-N-methyl-D-aspartate receptors monoclonal antibodies (HuMAbs) into the small brain regi
