Porcine epidemic diarrhea virus deficient in RNA cap guanine-N-7 methylation is attenuated and induces higher type I and III interferon responses
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
The 5' cap methylation of viral RNA plays an important role in RNA stability, efficient translation, and immune evasion. Thus, RNA cap methylation is an attractive target for antiviral discovery and development of new live attenuated vaccines. For coronaviruses, RNA cap structure is first methylated

Logi sisse
Porcine epidemic diarrhea virus (PEDV) LJB/03 was isolated from the fece of piglets infected with PEDV on a pig farm, Heilongjiang province, China. The M gene of LJB/03 was amplified from the RNA extracted directly from the fece samples by RT-PCR and cloned into pMD18-T vector. The M gene cDNA was

The RNA-dependent RNA polymerase of the hepatitis C virus and the bovine viral diarrhea virus(BVDV)is able to initiate RNA synthesis denovo in the absence of a primer. Previous crystallographic data have pointed to the existence of a GTP-specific binding site (G-site) that is located in the vicinity

The nucleocapsid (N) gene of the porcine epidemic diarrhea virus (PEDV) strain LJB/03 which was previously isolated in Heilongjiang province, China, was cloned, sequenced and compared with published sequences of other avian and mammalian coronavirus. The nucleotide sequence encoding the entire N
The Guanine Nucleotide Exchange Factor GBF1 Participates in Rotavirus Replication.

Logi sisse
Cellular and viral factors participate in the replication cycle of rotavirus. We report that the guanine nucleotide exchange factor GBF1, which activates the small GTPase Arf1 to induce COPI transport processes, is required for rotavirus replication since knocking down GBF1 expression by RNA

A case of chronic secretory diarrhea with elevated plasma vasoactive intestinal peptide (VIP) and serum gastrin levels is described. Plasma secretin, glucagon, insulin, and cyclic adenosine and guanine monophosphate (cAMP and (CGMP) concentrations were normal. Administration of a prostaglandin
Deletion in the Shigella enterotoxin genes further attenuates Shigella flexneri 2a bearing guanine auxotrophy in a phase 1 trial of CVD 1204 and CVD 1208.

BACKGROUND
We created a live, attenuated, oral Shigella vaccine by constructing a lineage of guanine auxotrophs and conducted a double-blind, placebo-controlled trial to ascertain (1) the attenuation profile of Delta guaBA Shigella flexneri 2a, which harbors deletions in the guanine nucleotide
Activation of Escherichia coli heat-labile enterotoxins by native and recombinant adenosine diphosphate-ribosylation factors, 20-kD guanine nucleotide-binding proteins.
