Polyomavirus JC microRNA expression after infection in vitro

Autor: Nunzia Della Malva, Simone Giannecchini, Daniele Nosi, Irene Giovannelli, Souichi Nukuzuma, Valeria Clausi

Publikováno v: Virus research. 213

The in vitro expression of the Polyomavirus JC (JCPyV) microRNAs, JC-miRNA-3p and -5p, at early time points post-infection was investigated. The expression of the JCPyV microRNAs was monitored in hematopoietic progenitor KG-1 cells and in kidney fibr

Publikováno v: Virus research. 180

Amino acid substitutions which can affect the receptor binding specificity of the influenza virus, like the substitution of aspartic acid with glycine in position 222 of the haemagglutinin (HA) of influenza virus A(H1N1) 2009, have been associated wi

Packaging signals in the 5'-ends of influenza virus PA, PB1, and PB2 genes as potential targets to develop nucleic-acid based antiviral molecules

Autor: Isabella Donatelli, Valeria Clausi, Edoardo Del Poggetto, Simone Giannecchini, Helen M. Wise, Liberio Vesco, Simona Puzelli, Paul Digard, Alberta Azzi

Publikováno v: Antiviral research. 92(1)

In a previous study a 15-mer phosphorothioate oligonucleotide (S-ON) derived from the packaging signal in the 5' end of segment 1 (PB2) of influenza A virus (designated 5-15b) proved markedly inhibitory to virus replication. Here we investigated whet

Increased pathogenicity and shedding in chickens of a wild bird-origin low pathogenicity avian influenza virus of the H7N3 subtype following multiple in vivo passages in quail and turkey

Autor: Valeria Clausi, Filippo Cilloni, Calogero Terregino, Anna Toffan, Simone Giannecchini, Alberta Azzi, Ilaria Capua

Publikováno v: Avian diseases. 54

In order to investigate viral adaptation mechanisms to poultry, we performed serial in vivo passages of a wild bird low pathogenicity avian influenza isolate of the H7N3 subtype (A/mallard/Italy/33/01) in three different domestic species (chicken, tu

A FRET based melting curve analysis to detect nucleotide variations in HA receptor-binding site of H5N1 virus

Autor: Florigio Lista, Giovanni Faggioni, Fabiana Corcioli, Valeria Clausi, Alberta Azzi, Andrea Ciammaruconi, Silvia Fillo, R. De Santis

Publikováno v: Molecular and cellular probes. 24(5)

Outbreaks of highly pathogenic H5N1 influenza A virus represent a major public health problem because of the possibility of direct transmission of these viruses from avian species to humans. For influenza H5N1 hemagglutinin, a switch from SA-a-2, 3-G

Oligonucleotides derived from the packaging signal at the 5' end of the viral PB2 segment specifically inhibit influenza virus in vitro

Autor: Valeria Clausi, Daniele Nosi, Simone Giannecchini, Alberta Azzi

Publikováno v: Archives of virology. 154(5)

The development of new antiviral molecules to fight the possible emergence of influenza viruses with pandemic potential is needed. In this study, phosphorothioate oligonucleotides (S-ONs) derived from the packaging signals in the 3′ and 5′ ends o
