Dynamic protein behavior drives blood-brain barrier specialization, study reveals

A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC), in collaboration with the Proteomics Platform of the Institute for Research in Biomedicine (IRB Barcelona), has uncovered a key mechanism that helps define how the blood-brain barrier functions—not just based on which proteins are present, but on how dynamically they are used.
