New research shows SARS-CoV-2 spike proteins disrupt the blood-brain barrier

New work by scientists at the Lewis Katz School of Medicine at Temple University shows that the spike proteins that extrude from SARS-CoV-2 promote inflammatory responses on the endothelial cells that form the blood-brain barrier. The study, published in the December print issue of the journal Neurobiology of Disease, is the first to show that SARS-CoV-2 spike proteins can cause this barrier to become “leaky,” potentially disrupting the delicate neural networks within the brain.
