Viral disruption of the blood–brain barrier

Abstract

The blood-brain barrier (BBB) provides significant protection against microbial invasion of the brain. However, the BBB is not impenetrable, and mechanisms by which viruses breach it are becoming clearer. In vivo and in vitro model systems are enabling identification of host and viral factors contributing to breakdown of the unique BBB tight junctions. Key mechanisms of tight junction damage from inside and outside cells are disruption of the actin cytoskeleton and matrix metalloproteinase activity, respectively. Viral proteins acting in BBB disruption are described for HIV-1, currently the most studied encephalitic virus; other viruses are also discussed.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Viral infection affects BBB integrity by mechanisms including phosphorylation of tight junction proteins, disruption of the basal lamina or of the actin cytoskeleton, or by invading BBB-epithelial cells and furthermore astrocytes.

    “Viral infection also affects BBB integrity by different mechanisms, including phosphorylation of tight junction proteins, disruption of the basal lamina or of the actin cytoskeleton, or by invading BBB-epithelial cells and furthermore astrocytes [10, 31].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
