摘要:
The present invention relates to a system for the heterologous expression of a viral protein or a fragment thereof, said system comprising a) a ciliate host cell, b) at least one cDNA encoding for a viral protein, or a fragment thereof, and c) a promoter operably linked to said cDNA.
摘要:
Described is a method for isolating Hepatitis C Virus peptides (HPs) which have a binding capacity to a MHC/HLA molecule or a complex comprising said HCV-peptide and said MHC/HLA molecule characterized by the following steps: - providing a pool of HCV-peptide, said pool containing HCV-peptides which bind to said MHC/HLA molecules and HCV-peptides which do not bind to said MHC/HLA molecule, -contacting said MHC/HLA molecule with said pool of HCV-peptides whereby a HCV-peptide which has a binding capacity to said MHC/HLA molecule binds to said MHC/HLA molecule and a complex comprising said HCV-peptide and said MHC/HLA molecule is formed, -detecting and optionally separating said complex from the HCV-peptide which do not bind to said MHC/HLA molecule and optionally isolating and characterising the HCV-peptide from said complex.
摘要:
The present invention provides novel canine pol I regulatory nucleic acid sequences useful for the expression of nucleic acid sequences in canine cells such as MDCK cells. The invention further provides expression vectors and cells comprising such nucleic acids as well as methods of using such nucleic acids to make influenza viruses, including infectious influenza viruses.
摘要:
The present invention discloses isolated peptides encoding an antigen or fragments thereof from the N-terminus of hemagglutinin protein of influenza, methods for isolating such antigens and specific uses thereof. The peptide can be used as a vaccine to generate an antibody response that neutralizes influenza infectivtty against a variety of influenza strains.
摘要:
The present invention provides methods of differentiating the infectivity and lethality of isolates of influenza virus and provides compounds for diagnosing, preventing, and treating outbreaks of influenza virus including compounds for diagnosing, preventing, and treating across different strains of influenza virus.
摘要:
The present invention provides a vaccine composition for transnasal mucous membrane administration, which contains an influenza virus antigen, polyriboinosinic polyribocytidylic acid (poly (I:C)) or a derivative thereof and a carboxyvinyl polymer. The present invention also provides a prophylactic method of influenza, including a step of administering the vaccine composition at least once to the nasal mucosa of a subject in need thereof.
摘要:
Immunogenic compositions comprising partially glycosylated viral glycoproteins for use as vaccines against viruses are provided. Vaccines formulated using mono-, di-, or tri-glycosylated viral surface glycoproteins and polypeptides provide potent and broad protection against viruses, even across strains. Pharmaceutical compositions comprising monoglycosylated hemagglutinin polypeptides and vaccines generated therefrom and methods of their use for prophylaxis or treatment of viral infections are disclosed. Methods and compositions are disclosed for influenza virus HA, NA and M2, RSV proteins F, G and SH, Dengue virus glycoproteins M or E, hepatitis C virus glycoprotein E1 or E2 and HIV glycoproteins gp120 and gp41.
摘要:
The present invention refers to a method for producing viruses, selected from the group of flaviviridae, poxviridae and reoviridae and vaccines derived therefrom as well as to cells cultured under protein-free conditions. These cells show improved capabilities for propagating viruses, and eliminate the need for costly and time-consuming viral passaging und purification.
