Immune Responses and Protection Induced by DNA Vaccines Encoding Bovine Parainfluenza Virus Type 3 Glycoproteins

Hemagglutinin and/or Fusion Proteins DNA Vaccines Encoding Measles Virus Induced by Intramuscular Vaccination with Characterization of Immune Responses

Characterization of immune responses induced by intramuscular vaccination with DNA vaccines encoding measles virus hemagglutinin and/or fusion proteins.

Measles virus (MV) hemagglutinin (MV-H) and fusion (MV-F) proteins induce plaque reduction neutralizing (PRN) antibodies and cell-mediated immune responses that protect against clinical measles. DNA vaccines that encode MV-H and MV-F are being investigated as a new generation of measles vaccine to protect infants too young to receive currently licensed attenuated measles vaccines. However, it i...

th۱ platform immune responses against leishmania major induced by thiol-specific antioxidant-based dna vaccines

background: the thiol-specific antioxidant (tsa) is an antigen of leishmania major which is believed to be the most promising molecule as a vaccine candidate against leishmaniasis. objectives: in this study, we investigated the protective efficacy of tsa-based dna vaccine against l. major infection. materials and methods: recombinant plasmid construction tsa (pctsa) was prepared and transfected...

Bovine parainfluenza type 3 virus infection: virus replication in bovine embryonic cell cultures and virion separation by rate-zonal centrifugation.

Replicative sequences of a bovine strain of parainfluenza type 3 virus in bovine embryonic kidney and spleen cell cultures were investigated by light and fluorescence microscopy and by ultrathin section and negative-contrast electron microscopy. Observations from light and fluorescence microscopy showed that intracytoplasmic inclusions were detected as small granules surrounding the nuclei of m...

Role of individual glycoproteins of human parainfluenza virus type 3 in the induction of a protective immune response.

Affinity-purified hemagglutinin-neuraminidase (HN) and fusion (F) glycoproteins of human parainfluenza virus type 3 (P13 virus) were used to investigate their role in the induction of a protective immune response following immunization of hamsters. The efficacy of immunization with the glycoprotein antigens was tested by challenge infection. Results of virus recovery from lungs and trachea demo...
