    Abstract: The polynucleotides of the present invention are complementary to the Initiation Sites of microbes. Invading organisms, sensing the pH and nutrient deprivation of a physiologic environment quickly release these nucleotides triggering rapid growth and mutation—attributes to successfully establishing a nidus of infection. They also stimulate neutrophil functions. Accordingly, the nucleotides, compositions and methods of the present invention may be used to enhance, restore or stimulate an immune response or system of an animal, e.g. to prevent an infection caused by a microorganism, ameliorate an infection caused by a microorganism, or kill an invading microorganism that causes infection or re-establish balance to an immune system. In particular, the polynucleotides, compositions and methods of the present invention may be used to treat or prevent bacterial infections and auto-immune diseases in a mammal in need thereof.

  • Patent number: 7947281
    Abstract: The present invention is related to the obtaining of chimeric chains coding for proteins capable of inducing, in the recipient, a serotype-specific and protective humoral immune response against the infection by the Dengue virus, thus eliminating the effects of the serotype-nonespecific viral immunoenhancement that causes hemorrhagies and clinical complications described for this kind of pathology. These chimeric chains of nucleic acids are composed by the specific combination of fragments belonging to the gene of a mutated protein from Neisseria meningitidis with dehydrogenase activity and fragments that codify for a region of the envelope (E) protein from the Dengue virus which, when inserted to an expression vector, give rise to chimeric proteins with particular properties. The resultant chimeric molecules from this invention are applicable to the pharmaceutical industry for the obtaining of vaccine preparations and diagnostic means of high serotype-specificity to be used in humans.

  • Patent number: 7943134
    Abstract: Cellular receptors are identified that induce plasma leakage and other negative effects when infected with flaviviruses, such as dengue virus or Japanese encephamyelitis virus. Using fusion proteins disclosed herein, the receptors to which a pathogen, such as flavivirus, binds via glycan binding are determined. Once the receptors are determined, the effect of binding to a particular receptor may be determined, wherein targeting of the receptors causing a particular symptom may be targeted by agents that interrupt binding of the pathogen to the receptor. Accordingly, in the case of dengue virus and Japanese encephamyelitis virus, TNF-? is released when the pathogen binds to the DLVR1/CLEC5A receptor. Interrupting the DLVR1/CLEC5A receptor with monoclonal antibodies reduced TNF-? secretion without affecting secretion of cytokines responsible for viral clearance thereby increasing survival rates in infected mice from nil to around 50%.

  • Publication number: 20110052634
    Abstract: The present invention discloses an attenuated recombinant alphavirus that is incapable of replicating in mosquito cells and of transmission by mosquito vectors. These attenuated alphavirus may include but is not limited to Western Equine Encephalitis virus, Eastern equine encephalitis virus, Venezuelan equine encephalitis virus or Chikungunya virus. The present invention also discloses the method of generating such alphaviruses and their use as immunogenic compositions.

  • Publication number: 20110020393
    Abstract: The present inventors improved methods for inactivating Japanese encephalitis virus vaccines, and assessed the safety of vaccines produced by combining multiple vaccines. The present inventors successfully produced safer Japanese encephalitis vaccines by cell culture, which can be stored more stably over a long period than conventional Japanese encephalitis vaccines. Furthermore, it is also expected that the production methods can be used to produce other viral vaccines with excellent storage stability.

  • Publication number: 20110014233
    Abstract: A method to prepare inactivate viral vaccine by exposing the virus to a predetermined concentration of an inactivating psoralen, and a preselected intensity of ultraviolet radiation for a time period sufficiently long to render the virus non-infectious but less than that which would result in degradation of its antigenic characteristics.

  • Patent number: 7871814
    Abstract: The present invention provides recombinant bicistronic flaviviruses, particularly live attenuated recombinant bicistronic flavivirus, which comprise, in order from 5? to 3?, a viral 5?UTR, an ORF encoding all viral proteins, an internal ribosome entry site, an exogenous nucleotide sequence that encodes an exogenous polypeptide, and a viral 3?UTR. Infection of a host cell with a recombinant flavivirus provides for expression of the exogenous nucleic acid in a host cell. Such recombinant flavivirus are useful for delivering a protein to a mammalian host; and for eliciting an immune response to the exogenous polypeptide.
