Pseudorabies virus (PRV), the etiological pathogen of Aujeszky's disease, belongs to the Alphaherpesvirus subfamily. Large latency transcript (LLT), the most abundant PRV transcript, harbors a ~ 4.6 kb microRNA (miRNA) cluster-encoding intron. To investigate the function of the LLT miRNA cluster during the life cycle of PRV, we generated a miRNA cl...

The human T-cell leukemia virus type-1 (HTLV-1) is an oncoretrovirus that infects and transforms CD4+ T-cells and causes adult T-cell leukemia/lymphoma (ATLL) -an aggressive lymphoproliferative disease that is highly refractive to most anticancer therapies. The HTLV-1 proviral genome encodes several regulatory products within a conserved 3' nucleot...

Nucleoprotein (NP) is a major component of the viral ribonucleoprotein (vRNP) complex that is responsible for viral replication, transcription and packaging of influenza A virus. Phosphorylation of NP plays an important role during viral infection. In the present study, we identified threonine 188 (T188) as a novel phosphorylated residue in the NP ...

Infections have been suggested to be involved in Multiple Sclerosis (MS). We used metagenomic sequencing to detect both known and yet unknown microorganisms in 2 nested case control studies of MS. Two different cohorts were followed for MS using registry linkages. Serum samples taken before diagnosis as well as samples from matched control subjects...

Herpes simplex virus 2 (HSV-2) is the leading cause of genital herpes and increases the risk of HIV infection, but there is no effective vaccine. A replication-defective HSV-2 mutant virus, dl5-29, is effective in animal models and has been in a phase I trial. Previous studies have shown that dl5-29 gives higher antibody responses and better protec...

AAV-mediated gene therapy has become a promising therapeutic strategy for chronic diseases. Its clinical utilization, however, is limited by the potential risk of off-target effects. In this work we attempt to overcome this challenge, hypothesizing that cardiac ion channel-specific ligands could be fused onto the AAV capsid, and narrow its tropism ...

Sf-rhabdovirus was only recently identified as an adventitious agent of Spodoptera frugiperda (Sf) cell lines used as hosts for baculovirus vectors. As such, we still know little about its genetic variation, infectivity, and the potential impact of variation on the Sf-rhabdovirus-host interaction. Here, we characterized Sf-rhabdoviruses from two wi...

Vaccinia virus (VACV), a member of the Poxviridae family, uses cytoplasmic factories for its replication. Recent studies indicated that VACV infection requires a set of nucleoporins. However, how the nucleoporins contribute to viral life cycle remains unclear. Here, we report that the nucleoporins Nup62 and Nup358 localize to the cytoplasmic viral ...

Cellular transformation by adenovirus E1A requires targeting TRRAP, a scaffold protein which helps assemble histone acetyltransferase complexes, including the NuA4 complex. We recently reported that E1A and E1A 1-80 (N-terminal 80 aa) promote association of the proto-oncogene product MYC with the NuA4 complex. The E1A N-terminal TRRAP-targeting (ET...

RSV is a major cause of severe lower respiratory infection in infants and young children. With no vaccine yet available, it is important to clarify mechanisms of disease pathogenesis. Since indoleamine-2,3-dioxygenase (IDO) is an immunomodulatory enzyme and is upregulated with RSV infection, we studied it in vivo during infection of BALB/c mice and...
