Immunomodulating polynucleotides are disclosed. The immunomodulating polynucleotides may contain 5-modified uridine, 5-modified cytidine, a total of from 6 to 16 nucleotides, and/or one or more abasic spacers and/or internucleoside phosphotriesters. Also disclosed are conjugates containing a targeting moiety and one or more immunomodulating polynucleotides. The immunomodulating polynucleotides and conjugates may further contain one or more auxiliary moieties. Also disclosed are compositions containing the immunomodulating polynucleotides or the conjugates containing one or more stereochemically enriched internucleoside phosphorothioates. Further disclosed are pharmaceutical compositions containing the immunomodulating polynucleotides or the conjugates and methods of their use.
