Abstract

Infection with mouse adenovirus type 1 (MAV-1) results in fatal acute encephalomyelitis in susceptible mouse strains via infection of brain endothelial cells. Wild-type (wt) MAV-1 causes less brain inflammation than an early region 3 (E3) null virus in C57BL/6 mice. A mouse brain microvascular endothelial cell line infected with wt MAV-1 had higher expression of mRNAs for the proinflammatory chemokines CCL2 and CCL5 than mock- and E3 null virus-infected cells. Primary mouse brain endothelial cells infected with wt virus had elevated levels of CCL2 compared to mock- or E3 null virus-infected cells. Infection of C57BL/6 mice with wt MAV-1 or the E3 null virus caused a dose-dependent breakdown of the blood-brain barrier, primarily due to direct effects of virus infection rather than inflammation. The tight junction proteins claudin-5 and occludin showed reduced surface expression on primary mouse brain endothelial cells following infection with either wt MAV-1 or the E3 null virus. mRNAs and protein for claudin-5, occludin, and zona occludens 2 were also reduced in infected cells. MAV-1 infection caused a loss of transendothelial electrical resistance in primary mouse brain endothelial cells that was not dependent on E3 or on MAV-1-induced CCL2 expression. Taken together, these results demonstrate that MAV-1 infection caused breakdown of the blood-brain barrier accompanied by decreased surface expression of tight junction proteins. Furthermore, while the MAV-1-induced pathogenesis and inflammation were dependent on E3, MAV-1-induced breakdown of the blood-brain barrier and alteration of endothelial cell function were not dependent on E3 or CCL2.

  • 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 [212]

    The Results report that mouse adenovirus infection increased chemokine expression in brain endothelial cells; the Discussion reports reduced tight-junction proteins and blood–brain barrier breakdown (pages unavailable). The Results identify VCAM as a marker already expressed by the endothelial cells, not as an infection-induced increase. The paper discusses several viruses, but does not establish this entire sequence as a general mechanism for viral entry into the brain. (LLM, conf=0.88)

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.
