Abstract

See full text

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 45.degree. C., and (iii) resulting in an increased ratio of processed mRNA encoding ligand-independent CTLA-4 to processed mRNA encoding full-length CTLA-4.
