COMPOSITIONS AND METHODS FOR ACTIVATING STIMULATOR OF INTERFERON GENE -DEPENDENT SIGNALLING

摘要

The present invention provides highly active cyclic-di-nucleotide (CDN) immune stimulators that activate DCs via a recently discovered cytoplasmic receptor known as STING (Stimulator of Interferon Genes), In particular, the CDNs of the present invention are provided in the form of a composition comprising one or more cyclic purine dinucleotides induce human STING-dependent type I interferon production, wherein the cyclic purine dinuclotides present in the composition are 2'-fluoro substituted, bis-3',5'CDNs, and most preferably one or more 2',2"-diF-Rp,Rp, bis-3',5'CDNs.
