摘要:
Various genes of herpes virus of turkeys (HVT), Marek's disease virus (MDV) and infectious laryngotracheitis virus (ILTV) have been identified as non-essential regions (and candidates for insertion sites for foreign genes) and/or as antigen-encoding regions. The former include the HVT homologue of the HSV (herpes simplex virus) gC gene, the TE (thymidine kinase) region of MDV or ILTV, ORF3 of ILTV (as defined herein), the ribonucleotide reductase (large subunit) gene of ILTV, MDV or HVT and the ribonucleotide reductase (small subunit) gene of MDV. The antigen-encoding regions include the HVT homologues of the HSV gB, gC and gH genes, the ILTV homologue of HSV gB, ORF2 of ILTV, and the HVT homologue of the HSV-1 immediate early genes IE-175 and IE-68. Manipulation of these genes allows vaccines to be prepared comprising attenuated virus or virus carrying heterologous antigen-encoding sequences.
摘要:
Structural phosphoprotein (pp28) of human cytomegalovirus (HCMV), the preparation and use thereof Expression of an SmaI fragment, which is about 1.0 kb in size, on the left-hand end of the HindIII R fragment makes it possible to synthesize, by genetic manipulation, a structural phosphoprotein of HCMV. This phosphoprotein, or immunogenic parts thereof, can be used as diagnostic aid or vaccine.
摘要:
Disclosed herein are fusion proteins, nucleotide sequences for creating them, and vectors containing the nucleotide sequences. The fusion proteins have a bovine herpesvirus protein linked to a biotherapeutic protein or reporter protein. They rapidly spread biotherapeutic or reporter protein throughout mammalian cells.
摘要:
The present invention provides recombinant DNA molecules comprising a sequence encoding a pseudorabies virus (PRV) glycoprotein selected from the group consisting of gI, gp50, and gp63, host cells transformed by said recombinant DNA molecule sequences, the gI, gp50 and gp63 polypeptides. The present invention also provides subunit vaccines for PRV, methods for protecting animals against PRV infection and methods for distinguishing between infected and vaccinated animals.
