The mitochondrial carrier homolog 2 is involved in down-regulation of influenza A virus replication.

Background: The mitochondrial carrier homolog 2 (MTCH2) is a mitochondrial outer membrane protein regulating mitochondrial metabolism and functions in lipid homeostasis and apoptosis. Experimental data on the interaction of MTCH2 with viral proteins in virus-infected cells are very limited. Here, the interaction of MTCH2 with PA subunit of influenza A virus RdRp and its effects on viral replication was investigated.

An in silico prediction of interaction models of influenza A virus PA and human C14orf166 protein from yeast-two-hybrid screening data.

The human C14orf166 protein, also known as RNA transcription, translation, and transport factor, shows positive modulatory activity on the cellular RNA polymerase II enzyme. This protein is a component of the tRNA-splicing ligase complex and is involved in RNA metabolism. It also functions in the nucleo-cytoplasmic transport of RNA molecules.

Effects of Some Interferon-Related Proteins on Influenza A Viruse RNA Polymerase Activity.

Objectives: Interferons (IFNs) are one of the most important components of innate immunity against viruses, especially those carrying the RNA genomes such as influenza viruses. Upon viral infection, the IFNs are rapidly secreted, inducing the expression of several genes in the target cells and establishing an antiviral state. In this study, the effects of proteins encoded by some IFN-related genes on influenza A virus RNA-dependent RNA polymerase enzyme were investigated.

Stenotrophomonas maltophilia outbreak with a commercial blood gas injector as the culprit and interventions for source and prevention: A possible passage between patient and ECMO water heater device.

Background: Despite low virulence of Stenotrophomonas maltophilia, it represents one of the leading drug-resistant bacteria. We report a large outbreak of S. maltophilia infection associated with an unexpected source, which turned out to be a commercial needleless blood gas injector.

Human sorting nexin 2 protein interacts with Influenza A virus PA protein and has a negative regulatory effect on the virus replication.

Background: Replication of the influenza A viruses occurs in the cells through the viral RdRP consisting of PB1, PB2, and PA. Several cellular proteins are involved in these processes. This study aims to reveal the interaction between human SNX2 protein and the PA protein and the effects of the SNX2 on the virus replication.

Expression profiles of interferon-related genes in cells infected with influenza A viruses or transiently transfected with plasmids encoding viral RNA polymerase.

Influenza A viruses frequently change their genetic characteristics, which leads to the emergence of new viruses. Consequently, elucidation of the relationship between influenza A virus and host cells has a great importance to cope with viral infections. In this study, it was aimed to determine expression profiles of interferon response genes in human embryonic kidney 293 (HEK293) cells infected with human (A/WSN-H1N1) and avian influenza A viruses (duck/Pennsylvania/10218/84/H5N2) or transfected with plasmids encoding viral RdRP subunits and, to obtain clues about the genes that may be important for the viral pathogenesis.
