In all the three cell types, despite efficient virus infection, as indicated by the expression of N protein and syncytia formation, no SGs formation could be detected from 0 to 8 hours post-infection (h.p.i.), whereas from 12 to 24 h.p.i., G3BP1 granules could be detected, but only in approximately 5%-25% of infected cells (Fig 1A–1C). The gene discussed is G3BP1; the disease is viral infectious disease.
