Chimeric immunomodulatory compounds and methods of using the same—III
The invention provides immunomodulatory compounds and methods for immunomodulation of individuals using the immunomodulatory compounds.
1. A method of modulating an immune response in an individual comprising administering to an individual a branched chimeric immunomodulatory compound (CIC) in an amount sufficient to modulate an immune response in said individual, wherein: the CIC comprises at least three nucleic acid moieties and one or more non-nucleic acid, spacer moieties; each nucleic acid moiety is covalently joined to at least one non-nucleic acid spacer moiety; at least one nucleic acid moiety comprises the sequence 5′-CG-3′; and said CIC has immunomodulatory activity.
2. The method of modulating an immune response of claim 1 wherein the CIC has a fork structure, an H structure, a comb structure, or a central spacer structure.
3. A method of modulating an immune response of a population of cells, comprising contacting the population with a composition comprising a branched chimeric immunomodulatory compound (CIC) wherein: the CIC comprises at least three nucleic acid moieties and one or more non-nucleic acid spacer moieties; each nucleic acid moiety is covalently joined to at least one non-nucleic acid spacer moiety; at least one nucleic acid moiety comprises the sequence 5′-CG-3′; and said CIC has immunomodulatory activity.
4. The method of modulating an immune response of claim 3 , wherein the CIC has a fork structure, an H structure, a comb structure, or a central spacer structure.
5. A method of claim 1 wherein the immunomodulatory activity is an increase in interferon-α.
6. A method of claim 1 wherein at least one of the nucleic acid moieties comprises the sequence TCG in the 5′ position.
7. A method of claim 1 , wherein two or more of the nucleic acid moieties comprises the sequence TCG in the 5′ position.
