The present invention relates to the IL-12p40 subunit mutant gene which can produce IL-12 (interleukin 12) of human and mouse origin with high activity, the expression vector including above mutant gene and the use of them to DNA vaccine adjuvant. Particularly, it relates to IL-12p40 mutant gene which inhibits the secretion of IL-12p40 but normally secretes active IL-12p70 by making mutation at Asn-222 (human) or Asn-220 (mouse) amino acid of IL-12p40, which acts competitive inhibitor of active form of IL-12, IL-12p70. Therefore, the IL-12p40 mutant gene of the present invention can be useful for DNA vaccination and gene therapy to various diseases, for example, AIDS, hepatitis C or hepatitis B, cancer, influenza, tuberculosis and malaria, which essentially require cellular immune responses for thier therapy.

La présente invention concerne le gène mutant de la sous-unité IL-12p40, qui peut produire l'IL-12 (interleukine 12) d'origine humaine ou murine présentant une activité élevée. Elle concerne le vecteur d'expression comprenant ledit gène mutant, ainsi que leur utilisation dans un adjuvant de vaccin génétique. L'invention concerne en particulier le gène mutant IL-12p40 qui inhibe la sécrétion d'IL-12p40 mais sécrète normalement l'IL-12p70 active en effectuant une mutation à l'aminoacide de l'Asn-222 (humain) ou de l'Asn-220 (murin) d'IL-12p40, qui agit comme inhibiteur compétitif de la forme active d'IL-12, IL-12p70. Ainsi, le gène mutant IL-12p40 de l'invention peut être utilisé pour une vaccination génétique ou une thérapie génique contre diverses maladies (telles que, par exemple, le SIDA, l'hépatite C ou l'hépatite B, le cancer, la grippe, la tuberculose et le paludisme) qui nécessitent des réponses immunitaires cellulaires pour leur traitement.
