Abstract

AS-oligonucleotides are delivered in microsphere form in order to induce dendritic cell tolerance, particularly in the non-obese-diabetic (NOD) mouse model. The microspheres incorporate antisense (AS) oligonucleotides. A process includes using an antisense approach to reverse an autoimmune diabetes condition in NOD mice in vivo. The oligonucleotides are targeted to bind to primary transcripts CD40, CD80, CD86 and their combinations.
