Patent

CA 2635342

The invention relates to a pharmacological combination of a protein with cytoprotective properties and an immunomodulatory peptide. The peptide of the pharmacological combination is the linear LALF31-52 peptide which increases immunological defence mechanisms without inducing an exacerbated inflammatory response. The protein of the pharmacological combination is the epidermal growth factor which has a cytoprotective effect and which activates the signal transduction of cell survival genes. The inventive pharmacological combination confers resistance on the systemic immunocompetent cells in order to withstand damage caused by inflammatory cytokines and by bacterial endotoxins without activating molecular apoptosis pathways. In addition, the pharmacological combination alleviates the inflammatory events of the first stage of sepsis and of the inflammatory response against sterile traumatisms, thereby defending the organism against the invasion of pathogens or against inflammation mediators, without the inflammatory response being deleterious to the integrity thereof.

La présente invention concerne une combinaison pharmacologique d'une protéine ayant des propriétés cytoprotectrices et d'un peptide immunomodulateur. Le peptide de la combinaison pharmacologique est le peptide LALF31-52 linéaire, qui augmente les mécanismes de défense immunologique, sans induire de réaction inflammatoire exacerbée. La protéine de la combinaison pharmacologique est le facteur de croissance épidermique qui possède un effet cytoprotecteur et qui active la transduction de signaux de gènes de survie cellulaire. La combinaison pharmacologique de l'invention confère de la résistance aux cellules systémiques et immunocompétentes, ce qui permet de résister aux lésions provoquées par les cytokines inflammatoires et par les endotoxines bactériennes, sans activer de voies moléculaires de l'apoptose. De plus, la combinaison pharmacologique permet d'atténuer les événements inflammatoires de la première étape de la sepsie et de la réaction inflammatoire aux traumatismes stériles, ce qui permet de défendre l'organisme contre l'invasion de pathogènes ou contre les médiateurs de l'inflammation, sans que la réaction inflammatoire soit délétère pour son intégrité.
