Improved NYVAC-Based Vaccine Vectors
While as yet there is no vaccine against HIV/AIDS, the results of the phase III Thai trial (RV144) have been encouraging and suggest that further improvements of the prime/boost vaccine combination of a poxvirus and protein are needed. With this aim, in this investigation we have generated derivatives of the candidate vaccinia virus vaccine vector NYVAC with potentially improved functions. This...
متن کاملImproved Innate and Adaptive Immunostimulation by Genetically Modified HIV-1 Protein Expressing NYVAC Vectors
Attenuated poxviruses are safe and capable of expressing foreign antigens. Poxviruses are applied in veterinary vaccination and explored as candidate vaccines for humans. However, poxviruses express multiple genes encoding proteins that interfere with components of the innate and adaptive immune response. This manuscript describes two strategies aimed to improve the immunogenicity of the highly...
متن کاملAmplicons as vaccine vectors.
HSV-1 amplicon vectors efficiently transduce cultured antigen-presenting cells (APC), including both human and murine dendritic cells as well as primary human chronic lymphocytic leukemia (CLL) B cells. Helper-free amplicons have been shown to be especially well-suited for this purpose, since they do not impair the antigen-presenting functions of these target cells. In vivo, amplicon vectors ha...
متن کاملViral vectors for vaccine applications
Traditional approach of inactivated or live-attenuated vaccine immunization has resulted in impressive success in the reduction and control of infectious disease outbreaks. However, many pathogens remain less amenable to deal with the traditional vaccine strategies, and more appropriate vaccine strategy is in need. Recent discoveries that led to increased understanding of viral molecular biolog...
متن کاملSimian adenoviruses as vaccine vectors
Replication incompetent human adenovirus serotype 5 (HAdV-C5) has been extensively used as a delivery vehicle for gene therapy proteins and infectious disease antigens. These vectors infect replicating and nonreplicating cells, have a broad tissue tropism, elicit high immune responses and are easily purified to high titers. However, the utility of HAdV-C5 vectors as potential vaccines is limite...
