Scientists uncover a new role for blood-brain barrier in neuron function and damage

While the role of the blood-brain barrier has long been appreciated for its ability to maintain precise control over what molecules can enter the nervous system, very little is known about how the cells that form the barrier influence the function of the nervous system. “What we know currently about the blood-brain barrier is mostly that we don’t know much beyond the basics,” says Buck Institute professor Pejmun Haghighi, PhD, who has uncovered a new role for these cells.
