Dr. Gottlieb's research group is studying and characterizing bacteriophage f12, one of the newly identified members of the family Cystoviridae.These viruses contain a genome consisting of three segments of double-stranded RNA (dsRNA). Their mechanism of RNA packaging, replication and transcription is similar to that of the Reoviridae of which one member, rotavirus, is a major cause of infant gastroenteritis. To date, the cystoviruses are the only segmented dsRNA viruses that can be manipulated by recombinant genetic techniques, making them an excellent model for the study of the molecular biology of viruses of this type.
The laboratory has cloned and sequenced the three genomic segments and identified the viral genes. This analysis has better defined the evolutionary relationships among the members of this virus family. The genes of the virus have been expressed from the cDNA copies of the genome in E. coli and the viral proteins are now being studied, in particular the viral RNA-directed RNA polymerase P2. This study contributes to the understanding of the mechanism of viral RNA packaging and replication.
In a collaborative study with Dr. Spatz, the research group is investigating the role of the Epstein Barr Virus (EBV) in the etiology of Systemic Lupus Erythematosus (SLE). This research project focuses on characterizing the anti-double stranded DNA (dsDNA) response in mice that express the viral Epstein Barr Nuclear Antigen-1 (EBNA-1). The expression of this antigen in animals has been achieved through the use of DNA-based vaccination of recombinant plasmids. The establishment of this in vivo model enabled us to demonstrate that the inoculated mice produced antibodies to autoantigens associated with SLE.
