The technical field
The present invention relates to the field of molecular biology, in particular to the nucleotide sequence of the gene encoding the cytokine GM-CSF horses, to contain her expressing vectors, to its use as an adjuvant in vaccination of horses and as a non-specific stimulator of the immune system.
The first opening granulocyte-macrophage colony-stimulating factor (Granulocyte-Macrophage Colony-Stimulating Factor, or GM-CSF) dated 1977 (Burgess A.W., and others, J. Biol. Chem., 252, 1998-2003 (1977)). We are talking about GM-CSF mouse, isolated in pure form from the culture of supernatant the lungs of mice.
The biological activity of GM-CSF have been shown in research and GM-CSF mouse and humans (Clark, S.C., and others, 230, 1229 (1987); Grant S.M. and other, Drugs, 53, 516 (1992)).
GM-CSF is involved in various physiological processes (Dy M. in the book "Cytokines" Cavaillon, J. - M., 1996, ed. Masson, Paris, France, 43-56). In particular, GM-CSF stimulates the production, development and formation of colonies of granulocytes, macrophages, eosinophils and megakaryocytes. GM-CSF induces, in particular, makropoulou cytotoxicity, stimulates antibody-dependent cytotoxic activity (ADCC) and causes the recruitment of leukocytes at the level of areas of inflammation.
Currently identified GM-CSF various species of animals.
Nucleotide sequence codereuse the GM-CSF of various kinds, typically have a length of from 381 to 432 nucleotides. The homology between the nucleotide sequences of GM-CSF mouse and man is 69%. Homology of amino acid sequences is 54% (M.A. Cantrell and others, Proc/ Natl. Acad. Sci. USA, 82, 6250-6254 (1985)). However, despite the high homology, cross-physiological activity between GM-CSF human and mouse not detected (D. Metcalf and others, Blood, 67, 37-45 (1986)).
The introduction of heterologous GM-CSF, that is derived from other than the processed kind, it is not possible to achieve optimal adjuvant action, in particular the stimulation of the activity hemopoietic cells, and a significant strengthening of the immune response.
To date GM-CSF horse was not identified. However, this cytokine is of considerable interest for use in therapy and vaccination in the case of horses.
The aim of the invention was the selection and sequencing of the gene for GM-CSF horses. This gene was isolated by PCR with the use described in the examples of oligonucleotides.
The length of the gene GM-CSF horse is 432 nucleotide (sequence No. 8 and figure 1) and encodes a protein of 144 amino acids (sequence No. 9 and figure 1). Encoded by this gene protein has a homology of at least 75% amino acid sequence of GM-CSF other species.

The invention encompasses homologous to the nucleotide sequence of a horse or obtained synthetically, that is, a nucleotide sequence encoding a protein with functional activity and specificity, equivalently those of the horses. Of course, this includes nucleotide sequences that occur, taking into account the degeneracy of the genetic code. In particular, are equivalent DNA sequences having homology greater than or equal to 90%, preferably 92%, more preferably 95%, with an identified sequence No. 8.
The object of the present invention are DNA fragments that include the nucleotide sequence encoding GM-CSF horses, such as sequence No. 8, or a sequence encoding the amino acid sequence of No. 9, associated with a nucleotide sequence encoding at least one immunogen or at least one immunologically active fragment or men is our least one epitope of the immunogen. In this case, the DNA fragment does not contain a stop codon between the sequence encoding GM-CSF, and encoding the immunogen sequence. For example, in the case of sequence No. 8 built-in coding sequence ends with nucleotide 432 and does not include the stop codon.
The object of the present invention is also an isolated protein or fragment GM-CSF horses, for example, which is encoded by a nucleotide sequence No. 8 or homologous sequences, such as described above.
