Replication and packaging of transmissible gastroenteritis coronavirus-derived synthetic minigenomes.
The sequences involved in the replication and packaging of transmissible gastroenteritis virus (TGEV) RNA have been studied. The structure of a TGEV defective interfering RNA of 9.7 kb (DI-C) was described previously (A. Mendez, C. Smerdou, A. Izeta, F. Gebauer, and L. Enjuanes, Virology 217: 495-507, 1996), and a cDNA with the information to encode DI-C RNA was cloned under the control of the ...
متن کاملGeneration of a replication-competent, propagation-deficient virus vector based on the transmissible gastroenteritis coronavirus genome.
Replication-competent propagation-deficient virus vectors based on the transmissible gastroenteritis coronavirus (TGEV) genome that are deficient in the essential E gene have been developed by complementation within E(+) packaging cell lines. Cell lines expressing the TGEV E protein were established using the noncytopathic Sindbis virus replicon pSINrep21. In addition, cell lines stably express...
متن کاملAutophagy Negatively Regulates Transmissible Gastroenteritis Virus Replication
Autophagy is an evolutionarily ancient pathway that has been shown to be important in the innate immune defense against several viruses. However, little is known about the regulatory role of autophagy in transmissible gastroenteritis virus (TGEV) replication. In this study, we found that TGEV infection increased the number of autophagosome-like double- and single-membrane vesicles in the cytopl...
متن کاملStructural maturation of the transmissible gastroenteritis coronavirus.
During the life cycle of the transmissible gastroenteritis coronavirus (TGEV), two types of virus-related particles are detected in infected swine testis cells: large annular viruses and small dense viruses. We have studied the relationships between these two types of particles. Immunoelectron microscopy showed that they are closely related, since both large and small particles reacted equally ...
متن کاملSequence comparison of the 5' end of mRNA 3 from transmissible gastroenteritis virus and porcine respiratory coronavirus.
Analysis of porcine transmissible gastroenteritis virus (TGEV) and porcine respiratory coronavirus (PRCV) mRNA species indicated a deletion in mRNA 3 of PRCV. Polymerase chain reaction (PCR) was used to clone the 5' end of mRNA 3 from PRCV for comparison with the equivalent region in TGEV. Small deletions were observed within and around the PRCV sequence equivalent to the putative open reading ...
