SARS-CoV-2 spike S1 subunit protein-mediated increase of beta-secretase 1 (BACE1) impairs human brain vessel cells.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Increasing evidence suggests incomplete recovery of COVID-19 patients, who continue to suffer from cardiovascular diseases, including cerebral vascular disorders (CVD) and neurological symptoms. Recent findings indicate that some of the damaging effects of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, especially in the brain, may be induced by the spike protein, leading to the disruption of the initial blood-brain barrier (BBB). SARS-CoV-2-infected cells and animals exhibit age-dependent pathogenesis. In this study, we identified endothelial BACE1 as a critical mediator of BBB disruption and cellular senescence induced by the SARS-CoV-2 spike S1 subunit protein. Increased BACE1 in human brain microvascular endothelial cells (HBMVEC) decreases the levels of tight junction proteins, including ZO-1, occludin, and claudins. Moreover, BACE1 overexpression leads to the accumulation of p16 and p21, typical hallmarks of cellular senescence. Our findings show that the SARS-CoV-2 spike S1 subunit protein upregulated BACE1 expression in HBMVECs, causing endothelial leakage. In addition, the SARS-CoV-2 spike S1 subunit protein induced p16 and p21 expression, indicating BACE1-mediated cellular senescence, confirmed by β-Gal staining in HBMVECs. In conclusion, this study demonstrated that BACE1-mediated endothelial cell damage and senescence may be linked to CVD after COVID-19 infection.
