Differential effect of SARS-CoV-2 infection on stress granule formation in Vero and Calu-3 cells.

ABSTRACT: Stress granule formation is induced by numerous environmental stressors, including sodium arsenite treatment and viral infection. Accordingly, stress granules can inhibit viral propagation and function as part of the antiviral host response to numerous viral infections. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) antagonizes stress granule formation, in part, via interaction between SARS-CoV-2 nucleocapsid (N) protein and Ras-GTPase-activating SH3-domain-binding protein 1 (G3BP1). However, it is unclear whether there are differential effects in different cell types. In this study, we assessed interaction between the N protein of SARS-CoV-2 S clade and G3BP1/2 in Vero and Calu-3 cells and investigated the effect of various SARS-CoV-2 strains on sodium arsenite-induced stres
