SEPTIN9 and infection: Immunoblot data revealed a non-significant, time-dependent increase of septin 9 expression in non-infected cells, while septin 9 expression was significantly enhanced in JFH-1-infected cells (Fig. 2a), with the highest expression at 72 h of infection (Fig. 2a) when septin 9 formed bundles of filaments surrounding the clusters of HCV core (Fig. 2b).
