Estimating the term…
The present invention relates to a process for improving the immunogenicity of an immunogen, an antigen or a hapten, when it is administered to a host, independently of the mode of administration, characterized in that the said antigen or hapten is coupled covalently to a support molecule in order to form a complex, and in that this support molecule is a polypeptide fragment which is able to bind specifically to mammalian serum albumin. The invention also relates to the use, as a medicament, of the product which can be obtained in this way.
A process for improving the immunogenicity of an immunogen comprising covalently coupling an immunogen to a support molecule to form a complex, wherein said support molecule is a polypeptide fragment which binds specifically to mammalian serum albumin, and wherein said immunogen is derived from a surface glycoprotein selected from the group consisting of RSV surface glycoprotein F, RSV surface glycoprotein G, surface protein of hepatitis virus A, surface protein of hepatitis virus B, surface protein of hepatitis virus C, surface protein of the measles virus, surface protein of parainfluenza virus 3 and combinations thereof.
A process for improving the immunogenicity of an immunogen in vivo comprising the step of inserting or fusing DNA encoding an immunogen into DNA encoding a support whereby expression of the resulting DNA produces a complex, said complex comprising an immunogen covalently coupled to a support molecule, wherein said support molecule is a polypeptide fragment which binds specifically to mammalian serum albumin, and wherein said immunogen is derived from RSV surface glycoprotein:
A process for improving the immunogenicity of an immunogen in vivo comprising the step of inserting or fusing DNA encoding an immunogen into DNA encoding a support whereby expression of the resulting DNA produces a complex, said complex comprising an immunogen covalently coupled to a support molecule, wherein said support molecule is a polypeptide fragment which binds specifically to mammalian serum albumin, and wherein said immunogen is derived from the surface protein of hepatitis virus A, B or C.
A process for improving the immunogenicity of an immunogen in vivo comprising the step of inserting or fusing DNA encoding an immunogen into DNA encoding a support whereby expression of the resulting DNA produces a complex, said complex comprising an immunogen covalently coupled to a support molecule, wherein said support molecule is a polypeptide fragment which binds specifically to mammalian serum albumin, and wherein said immunogen is a surface protein of the measles virus.
