Highlights

The application of ultrasound and microbubbles (US + MBs) enhances the extravasation of macromolecular substance through blood–brain barrier via transcytosis mechanism.
The mechanical interaction between oscillating microbubbles and cell membranes results in direct membrane deformation and generates both mechanical and sonochemical effects.
The formation of pits on the cellular membrane surface is a critical step in the initiation of endocytosis or transcytosis processes.
US + MBs application induced membrane hyperpolarization and increase of cytosolic calcium concentration.
Mechanical interaction between oscillating microbubbles and cell membrane plays a necessary role in the dynamin-/caveolae-/clathrin- related transcytosis.
