Secondary structure prediction of the hemagglutinin-neuraminidase from a porcine rubulavirus

Archives of Virology, 1998
The Hemagglutinin-Neuraminidase (HN) from 'La Piedad, Michoacan' porcine rubulavirus (LPMV) interacts specifically with NeuAc alpha 2,3 lactose residues on the target cell. In this work we report the secondary structure of this protein, determined with five different theoretical algorithms.

Purification of the Porcine rubulavirus attachment protein by liquid isoelectric focusing

Protein Expression and Purification, 2004
Porcine rubulavirus (PoRV) is an emerging virus responsible for meningoencephalitis, respiratory distress, and reproductive alterations in pigs. The hemagglutinin-neuraminidase (HN) glycoprotein is the most exposed and antigenic of the virus proteins.

Comparative evaluation of the CD4+CD8+ and CD4+CD8− lymphocytes in the immune response to porcine rubulavirus

Veterinary Immunology and Immunopathology, 2001
The porcine immune system is unique in the expression of CD4+CD8+ (double-positive, DP) lymphocytes. These cells have been associated with immunological memory due to their gradual increase with age, the expression of memory phenotype and their ability to respond to recall viral antigen.

Tetherin antagonism by V proteins is a common trait among the genus Rubulavirus

Medical Microbiology and Immunology, 2017
Tetherin (BST-2/CD317/HM1.24) is an anti-viral factor that restricts the budding of several enveloped viruses. Most of these viruses have evolved to encode tetherin antagonists. Our previous study demonstrated that the growth of human parainfluenza virus type 2 (hPIV-2), a member of the genus Rubulavirus in the family Paramyxoviridae, was inhibited by ...

NeuAcα2,3Gal-Glycoconjugate Expression Determines Cell Susceptibility to the Porcine Rubulavirus LPMV

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1997
Relevance of membrane sialoglycoconjugates as receptors for infection by the porcine rubulavirus has been determined in vitro by sugar and lectin competition assays and by inhibition of glycosylation. Our results show that NeuAc alpha 2,3Gal but not NeuAc alpha 2,6Gal inhibits the virus infectivity of Vero cells, and the virus was effectively blocked ...

Genetic and antigenic changes in porcine rubulavirus.

Canadian journal of veterinary research = Revue canadienne de recherche veterinaire, 2012
Blue eye disease, caused by a porcine rubulavirus (PoRV), is an emergent viral swine disease that has been endemic in Mexico since 1980. Atypical outbreaks were detected in 1990 and 2003. Growing and adult pigs presented neurological signs, mild neurological signs were observed in piglets, and severe reproductive problems were observed in adults. Amino

Full-genome sequencing and phylogenetic analysis of four neurovirulent Mexican isolates of porcine rubulavirus

Archives of Virology, 2017
We report the complete genome sequences of four neurovirulent isolates of porcine rubulavirus (PorPV) from 2015 and one historical PorPV isolate from 1984 obtained by next-generation sequencing. A phylogenetic tree constructed using the individual sequences of the complete HN genes of the 2015 isolates and other historical sequences deposited in the ...

Neuraminidase activity of blue eye disease porcine rubulavirus: Specificity, affinity and inhibition studies

Research in Veterinary Science, 2017
Porcine rubulavirus (PorPV), also known as La Piedad Michoacan Virus (LPMV) causes encephalitis and reproductive failure in newborn and adult pigs, respectively. The hemagglutinin-neuraminidase (HN) glycoprotein is the most exposed and antigenic of the virus proteins. HN plays central roles in PorPV infection; i.e., it recognizes sialic acid-containing

Detection of viremia in the Porcine rubulavirus experimental infection

2004
El rubulavirus porcino (RVP) es causante de la enfermedad del ojo azul, que se manifiesta como una meningoencefalitis progresiva fatal en cerdos lactantes y con alteraciones reproductivas en cerdos adultos. El RVP es detectado principalmente en sistema nervioso central, sin embargo, también se ha logrado aislar de otros órganos como bronquios, pulmones,
