Abstract
This invention relates to Interleukin-12 fusion proteins and nucleic acid constructs encoding them, and to the use of such fusion proteins and constructs in tumour therapy, especially therapy of leukaemia. More particularly it relates to carrying out such therapy by means of cell therapy.
Claims15
A nucleic acid construct comprising a coding region encoding an interleukin-12 (IL-12) fusion protein, said fusion protein comprising:
- (a) an IL-12 p35 subunit;
- (b) an IL-12 p40 subunit;
- and (c) joining said subunits, a linker peptide, said construct further comprising a coding region encoding a B7 protein.
A viral vector comprising a nucleic acid construct comprising a coding region encoding an interleukin-12 (IL-12) fusion protein, said fusion protein comprising:
- (a) an IL-12 p35 subunit;
- (b) an IL-12 p40 subunit, and (c) joining said subunits, a linker peptide, said construct further comprising a coding region encoding a B7 protein.
A viral vector according to clain 5 wherein, in the encoded fusion protein, the p35 subunit is C-terminal to the p40 coding sequence.
A host cell transfected with a viral vector comprising a nucleic acid construct comprising a coding region encoding an interleukin-12 (IL-12) fusion protein said fusion protein comprising:
- (a) an IL-12 p35 subunit;
- (b) an IL-12 p40 subunit;
- and (c) joining said subunits, a linker peptide, said construct further comprising a coding region encoding a B7 protein.
A pharmaceutical composition comprising a viral vector comprising a nucleic acid construct, said construct comprising a coding region encoding an interleukin-12 (IL-12) fusion protein, said fusion protein comprising:
- (a) an IL-12 p35 subunit;
- (b) an IL-12 p40 subunit;
- and (c) joining said subunits, a linker peptide, said construct further comprising a coding region encoding a B7 protein;
- and a pharmaceutically acceptable carrier.
