Abstract

Though compromised blood-brain barrier (BBB) is a pathological hallmark of WNV-associated neurological sequelae, underlying mechanisms are unclear. We characterized the expression of matrix metalloproteinases (MMP) in WNV-infected human brain microvascular endothelial cells (HBMVE) and human brain cortical astrocytes (HBCA), components of BBB and their role in BBB disruption. Expression of multiple MMPs was significantly induced in WNV-infected HBCA cells. Naïve HBMVE cells incubated with the supernatant from WNV-infected HBCA cells demonstrated loss of tight junction proteins, which were rescued in the presence of MMP inhibitor, GM6001. Further, supernatant from WNV-infected HBCA cells compromised the in vitro BBB model integrity. Our data suggest astrocytes as one of the sources of MMP in the brain, which mediates BBB disruption allowing unrestricted entry of immune cells into the brain, thereby contributing to WNV neuropathogenesis. Because of the unavailability of WNV antivirals and vaccines, use of MMP inhibitors as an adjunct therapy to ameliorate WNV disease progression is warranted.

  • Viral infections in general downregulate TJ proteins and promote chemokine production and vascular cell adhesion molecule 1 (VCAM-1) expression in brain endothelial cells, thereby weakening the BBB and facilitating entry into the brain.

    “Viral infections in general downregulate TJ proteins and promote chemokine production and vascular cell adhesion molecule 1 (VCAM-1) expression in brain endothelial cells, thereby weakening the BBB and facilitating entry into the brain (5, 212, 399, 613).”

    From Blood-Brain Barrier: From Physiology to Disease and Back (2019) · cites this paper as [613]

    The Results and Discussion (page unavailable) show that MMPs released by WNV-infected astrocytes degrade tight-junction proteins in brain endothelial cells and weaken an in-vitro BBB model. They do not establish this as a general effect of viral infection or report the claimed chemokine production and VCAM-1 expression in endothelial cells. Indeed, the Results say direct WNV infection did not reduce endothelial ZO-1 staining. (LLM, conf=0.87)

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.
