Question: Paragraph: Positive-strand RNA viruses are known to rearrange cellular membranes to facilitate viral genome replication. The biogenesis and three-dimensional organization of these membranes and the link between replication and virus assembly sites is not fully clear. Using electron microscopy, we find Dengue virus (DENV)-induced vesicles, convoluted membranes, and virus particles to be endoplasmic reticulum (ER)-derived, and we detect double-stranded RNA, a presumed marker of RNA replication, inside virusinduced vesicles. Electron tomography (ET) shows DENV-induced membrane structures to be part of one ER-derived network. Furthermore, ET reveals vesicle pores that could enable release of newly synthesized viral RNA and reveals budding of DENV particles on ER membranes directly apposed to vesicle pores. Thus, DENV modifies ER membrane structure to promote replication and efficient encapsidation of the genome into progeny virus. This architecture of DENV replication and assembly sites could explain the coordination of distinct steps of the flavivirus replication cycle.

Question: Paragraph: Cox, E., Pensaert, M.B., Callebaut, P. and van Deun, K., 1990. Intestinal replication of a porcine respiratory coronavirus closely related antigenically to transmissible gastroenteritis virus. Vet. Microbiol., One-week-old piglets were inoculated with the porcine respiratory coronavirus (PRCV) either intravenously or directly into the lumen of the gastrointestinal tract. Both inoculation routes resulted in the isolation of virus from the caudal small intestine. Viral replication, however, was only observed upon inoculation into the digestive tract in quantities of > 10 3 TCIDso. Replication remained limited to a few unidentified cells located in or underneath the epithelial layer at villus-or crypt-sites. Virus was excreted in the faeces for several days but infection of the respiratory tract occurred rarely in the same pigs. The results of this study indicate that small changes in molecular structure between PRCV and transmissible gastroenteritis virus have resulted in important changes in host cell tropism.

Answer: False


Question: Paragraph: Severe acute respiratory syndrome (SARS) has become a global public health emergency. p38 mitogen-activated protein kinase (MAPK) and its downstream targets are activated in SARS coronavirus (SARS-CoV)-infected Vero E6 cells and activation of p38 MAPK enhances the cytopathic effects of SARS-CoV infection. In addition, weak activation of Akt cannot prevent SARS-CoV infection-induced apoptosis in Vero E6 cells. In the present study, we demonstrated that signal transducer and activator of transcription (STAT) 3, which is constitutively phosphorylated at tyrosine (Tyr)-705 and slightly phosphorylated at serine (Ser)-727 in Vero E6 cells, was dephosphorylated at Tyr-705 on SARS-CoV infection. In addition to phosphorylation of p38 MAPK in virus-infected cells, other MAPKs, i.e., extracellular signal-regulated kinase (ERK) 1/2 and c-Jun Nterminal kinase (JNK), were phosphorylated. Although inhibitors of ERK1/2 and JNK (PD98059 and SP600125) had no effect on phosphorylation status of STAT3, inhibitors of p38 MAPK (SB203580 and SB202190) partially inhibited dephosphorylation of STAT3 at Tyr-705. Tyr-705-phosphorylated STAT3 was localized mainly in the nucleus in mock infected cells, whereas STAT3 disappeared from the nucleus in virusinfected cells. As STAT3 acts as an activator of transcription in the nucleus, these results suggest that STAT3 lacks its activity on transcription in SARS-CoV-infected Vero E6 cells.
