A method and compound for suppressing an immune response in a mammalian subject, for the treatment or prevention of an autoimmune condition or transplantation rejection are disclosed. The compound is an antisense oligonucleotide analog compound having a targeting sequence complementary to a preprocessed CTLA-4 mRNA region identified by SEQ ID NO: 1 , spanning the splice junction between intron 1 and exon 2 of the preprocessed mRNA of the subject. The compound is effective, when administered to a subject, to form within host cells, a heteroduplex structure (i) composed of the preprocessed CTLA-4 mRNA and the oligonucleotide compound, (ii) characterized by a Tm of dissociation of at least 450C, and (iii) resulting in an increased ratio of processed mRNA encoding ligand-independent CTLA-4 to processed mRNA encoding full- length CTLA-4.

La présente invention concerne un procédé et un composé destinés à réprimer une réponse immunitaire chez un mammifère, pour le traitement ou la prévention d'une maladie auto-immune ou d'un rejet de transplantation. Le composé est un composé analogue d'un oligonucléotide antisens ayant une séquence de ciblage complémentaire à une région prétraitée de l'ARNm du CTLA-4 identifié par SEQ ID NO : 1, couvrant la jonction d'épissage entre l'intron 1 et l'exon 2 de l'ARNm prétraité du sujet. Le composé agit, lors de l'administration à un sujet, par formation, au sein de cellules hôtes, une structure hétéroduplex (i) composée de l'ARNm du CTLA-4 prétraité et du composé oligonucléotide, (ii) caractérisée par une Tm de dissociation d'au moins 45°C, et (iii) résultant en un rapport accru d'ARNm traité codant pour le CTLA-4 indépendant du ligand sur ARNm traité codant pour le CTLA-4 pleine longueur.
