Data confidence 85 high

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

SARS-CoV-2, the pathogenic virus that induces COVID-19 disease, contains four structural proteins in its virion. The nucleocapsid (N) protein is one of the four structural proteins that play a crucial role in the assembly of viral RNA into ribonucleoprotein. In addition, the N protein contributes to viral pathogenesis. One of the functions attributed to the N protein is the triggering of cytokine release by lung epithelial cells, macrophages, and monocytes. This study addresses the cellular effects of the N protein of SARS-CoV-2 on cells of glial origin. We report the upregulation of the RANTES chemokine in A172 glioblastoma cells at both the mRNA and protein levels in response to exposure to SARS-CoV-2 nucleocapsid protein. The N protein did not have an effect on cell viability and cell migration.
