infection of human endothelium in vitro by cytomegalovirus causes enhanced expression of purinergic receptors: a potential virus escape mechanism? | human cytomegalovirus (cmv) uses different strategies to escape from human host defense reactions. previously we have observed that infection of endothelial cells with cmv in vitro leads to enhanced activity of endothelial ectonucleotidases. these ectoenzymes are responsible for hydrolysis of extracellular adenine nucleotides, resulting in the formation of adenosine. infection with cmv in vivo therefore may result in local increase of adenosine production, providing an anti-inflammatory and anti ... | 2007 | 18049120 |
possible roles of transcription factors of pseudorabies virus in neuropathogenicity. | pseudorabies virus (prv) is also known by its taxonomic name, suid herpesvirus 1, or by its original name, aujeszky's disease virus. prv is a swine herpesvirus of the alphaherpesvirinae subfamily to which varicella-zoster virus (vzv) and herpes simplex virus type 1 (hsv-1) and type 2 (hsv-2) belong. prv is a pathogen of swine resulting in devastating disease and economic losses worldwide. it causes severe neurological disorders in infected piglets and latent infection in surviving pigs. prv also ... | 2007 | 18046989 |
the number of herpes simplex virus-infected neurons and the number of viral genome copies per neuron correlate with the latent viral load in ganglia. | the latent viral load is the most important factor that predicts reactivation rates of animals latently infected with herpes simplex virus (hsv). to estimate the latent viral load, individual latently infected mouse trigeminal ganglia were dispersed into single cell suspensions and plated into 96-well real-time pcr plates, and hsv-2 genome copies were measured. by assuming a poisson distribution for both the number of hsv-2 infected cells per well and the number of hsv-2 genome copies per infect ... | 2008 | 18045638 |
