Respiratory syncytial virus (RSV) fusion protein expressed by recombinant Sendai virus elicits B-cell and T-cell responses in cotton rats and confers protection against RSV subtypes A and B.

The respiratory syncytial virus (RSV) is a serious pediatric pathogen for which there is currently no clinically approved vaccine. This report describes the design and testing of a new RSV vaccine construct (rSV-RSV-F), created by the recombination of an RSV F sequence with the murine parainfluenza virus-type 1 (Sendai virus, SV) genome. SV was selected as the vaccine backbone for this study, because it has previously been shown to elicit high-magnitude, durable immune activities in animal studies and has advanced to human safety trials as a xenogenic vaccine for human parainfluenza virus-type 1 (hPIV-1).

Differentially regulated interferon response determines the outcome of Newcastle disease virus infection in normal and tumor cell lines.

Newcastle disease virus (NDV) is a negative-strand RNA virus with oncolytic activity against human tumors. Its effectiveness against tumors and safety in normal tissue have been demonstrated in several clinical studies. Here we show that the spread of NDV infection is drastically different in normal cell lines than in tumor cell lines and that the two cell types respond differently to beta interferon (IFN-beta) treatment.

Human parainfluenza virus type 1 but not Sendai virus replicates in human respiratory cells despite IFN treatment.

Sendai virus (SeV) and human parainfluenza virus type I (hPIV1) are highly homologous but have distinct host ranges, murine versus human. To identify the factors that affect the host specificity of parainfluenza viruses, we determined the infectivity and anti-IFN activities of SeV and hPIV1 in human and murine culture cells. SeV infected normal human lung MRC-5 and murine lung MM14.

Recombinant Sendai virus as a novel vaccine candidate for respiratory syncytial virus.

Respiratory syncytial virus (RSV) is among the most important and serious pediatric respiratory diseases, and yet after more than four decades of research an effective vaccine is still unavailable. This review examines the role of the immune response in reducing disease severity; considers the history of RSV vaccine development; and advocates the potential utility of Sendai virus (a murine paramyxovirus) as a xenogenic vaccine vector for the delivery of RSV antigens. The immunogenicity and protective efficacy of RSV-recombinant Sendai virus vectors constructed using reverse genetics is examined.

Safety and immunogenicity of intranasal murine parainfluenza virus type 1 (Sendai virus) in healthy human adults.

Human parainfluenza virus-type 1 (hPIV-1) is the most common cause of pediatric laryngotracheobronchitis (croup) and results in close to 30,000 US hospitalizations each year. No effective vaccine is available. We examined murine PIV-1 (Sendai virus, SeV) as a live, xenotropic vaccine for the closely related human PIV-1 in a phase I, dose escalation study in healthy adults.

Recombinant Sendai virus expressing the G glycoprotein of respiratory syncytial virus (RSV) elicits immune protection against RSV.

Although RSV causes serious pediatric respiratory disease, an effective vaccine does not exist. To capture the strengths of a live virus vaccine, we have used the murine parainfluenza virus type 1 (Sendai virus [SV]) as a xenogeneic vector to deliver the G glycoprotein of RSV. It was previously shown (J.
