The effects of poliovirus 3A protein expression and poliovirus infection on the presentation of hepatitis C virus antigens in cultured chimpanzee cells were examined. Expression of poliovirus 3A protein inhibits protein secretion when expressed in isolation and was sufficient to protect chimpanzee cells from lysis by hepatitis C virus-specific cytotoxic T(More)
Endoplasmic reticulum (ER)-to-Golgi traffic in yeast proceeds by the maturation of membrane compartments from post-ER vesicles to intermediate small vesicle tubular clusters (VTCs) to Golgi nodular membrane networks (Morin-Ganet et al., Traffic 2000; 1: 56-68). The balance between ER and Golgi compartments is maintained by COPII- and COPI-mediated(More)
Vesicle-mediated traffic between compartments of the yeast secretory pathway involves recruitment of multiple cytosolic proteins for budding, targeting, and membrane fusion events. The SEC7 gene product (Sec7p) is a constituent of coat structures on transport vesicles en route to the Golgi complex in the yeast Saccharomyces cerevisiae. To identify mammalian(More)
The rate of protein secretion in host cells is inhibited during infection with several different picornaviruses, with consequences likely to have significant effects on viral growth, spread, and pathogenesis. This Sin(+) (secretion inhibition) phenotype has been documented for poliovirus, foot-and-mouth disease virus, and coxsackievirus B3 and can lead to(More)
