GVs

Transcriptomic and proteomic responses to gas vesicle collapse in native and engineered bacterial systems

Gas vesicles (GVs) are air-filled protein nanostructures produced by microbes to regulate buoyancy and have emerged as powerful tools in biomedical imaging, particularly as acoustic reporter genes. Their mechanically robust shells enclose a stable air compartment, which collapses irreversibly when subjected to sufficient hydrostatic or acoustic pressure, leaving behind large protein sheets. This collapse phenomenon underlies key applications such as differential imaging and controlled...
