Identification Of Host Proteins Required For Vesicular Stomatitis Virus Infection, Debasis Panda
Identification Of Host Proteins Required For Vesicular Stomatitis Virus Infection, Debasis Panda
School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research
Viruses usurp host cell pathways for different stages of their infection. Understanding virus-host interaction will be invaluable to elucidate molecular mechanisms of virus infection and to identify drug targets. In order to identify such critical cellular genes in vesicular stomatitis virus (VSV, a model non-segmented negative strand RNA virus) infection, we developed a stable cell line constitutively expressing replication proteins of VSV. Attempts to establish a cell line replicating a sub-genomic replicon was not successful because of induction of interferon response by replication of viral genomic analog. Subsequently, we used siRNA technology and conducted a genome-wide siRNA screen in HeLa …

Porcine reproductive and respiratory syndrome virus (PRRSV) causes late-term abortion in sows and pneumonia in growing piglets. PRRSV evades the host immune response by several mechanisms, including the modulation of cytokine secretions in infected pigs, which is the subject of this dissertation. Particularly, PRRSV reduces the secretion of the pro-inflammatory cytokine, tumor necrosis factor-α (TNF-α) but increases the secretion of the anti-inflammatory cytokine interleukin-10 (IL-10). The latter effect, however, is PRRSV strain-specific. In this dissertation, we have examined mechanisms by which PRRSV regulates TNF-α and IL-10 expressions. The pathogenic strain FL12, derived from a PRRSV infectious clone, consistently suppressed TNF-α …

Like other α-herpesvirinae subfamily members, the primary site for bovine herpesvirus 1 (BHV-1) latency is ganglionic sensory neurons. Periodically BHV-1 reactivates from latency, virus is shed, and consequently virus transmission occurs. Transcription from the latency-related (LR) gene is readily detected in neurons of trigeminal ganglia (TG) of calves or rabbits latently infected with BHV-1. Two micro-RNAs and a transcript encompassing a small open reading frame (ORF-E) located within the LR promoter can also be detected in TG of latently infected calves. A BHV-1 mutant that contains stop codons near the beginning of the first open reading frame (ORF2) within the …
