Abstract
A process for obtaining Herpes Simplex virus type 1 (HSV-1) glycoprotein I (gI) from cells which have been infected or transformed with a recombinant Baculovirus is disclosed. The gI produced is then isolated and purified for use in immunotherapy against HSV infections.
Claims21
A vaccine against Herpes Simplex Virus infection, comprising Herpes Simplex Virus Type 1 (HSV-1) gI produced by the expression of a recombinant baculovirus having a genetic construct which comprises:
- a) a gene sequence encoding at least one of a full length HSV-1 gI (SEQ ID No. 1) and HSV-1 gI truncated by removal of a fragment encoding the transmembrane anchor sequence;
- and
- b) a promoter sequence wherein said gI gene sequence is functionally linked to the regulatory elements of said promoter, and wherein said promoter is operative in a baculovirus expression system.
A vaccine for the treatment or prevention of Herpes Simplex Virus 1 infection comprising at least one of full length Herpes Simplex Virus Type 1 (HSV-1) gI and HSV-1 gI truncated by removal of the transmembrane anchor sequence.
A process for preparing a vaccine against Herpes Simplex Virus 1 infection, comprising the steps of:
- preparing a recombinant baculovirus having a genetic construct which comprises a gene sequence encoding at least one of a full length Herpes Simplex Virus Type 1 (HSV-1) gI (SEQ ID No. 1) and HSV-1 gI truncated by removal of a fragment encoding the transmembrane anchor sequence, and a promoter sequence wherein said gI gene sequence is functionally linked to the regulatory elements of said promoter, and wherein said promoter is operative in a baculovirus expression system;
- introducing the recombinant baculovirus into a first set of host cells;
- culturing the host cell;
- and
- recovering said HSV-1 gI from the culture.
