CANX and infection: To identify the cytoplasmic compartment(s) in which viral HCV proteins accumulated during infection of HeLa cells with VT7-HCV7.9, we performed immunofluorescence analysis using serum from an HCV-infected patient to recognize HCV proteins and antibodies specific for the Golgi apparatus (anti-gigantin), the endoplasmic reticulum (anti-calnexin) or the mitochondria (mitotracher) (Fig. 1).
