Abstract
The invention relates methods and products for inducing mucosal immunity. In particular, the invention relates to the use of immunostimulatory oligonucleotides containing a CpG motif for inducing mucosal immunity. The CpG immunostimulatory oligonucleotides may be administered alone or in combination with antigen and/or with other adjuvants.
Claims52
A method for inducing a mucosal immune response, comprising:
- administering to a subject in need of a mucosal immune response an effective amount for inducing a mucosal immune response of an oligonucleotide 8 to 100 nucleotides in length, having a sequence including at least the following formula:
- 5′X1X2CGX3X4 3′
- wherein C is unmethylated, wherein X1, X2, X3, and X4 are nucleotides, and
- an antigen,
- wherein the antigen is not encoded in a nucleic acid vector, the oligonucleotide and the antigen are both administered vaginally, rectally, intranasally, ocularly, or by inhalation to the subject, a cytokine and an immune stimulating complex are not administered to the subject, and the antigen is not a Streptococcus pneumoniae antigen.
A method for inducing a mucosal immune response, comprising:
- administering to a subject in need of a mucosal immune response an effective amount for inducing a mucosal immune response of an oligonucleotide 8 to 100 nucleotides in length, having a sequence including at least the following formula:
- 5′X1X2CGX3X4 3′
- wherein C is unmethylated, wherein X1, X2, X3, and X4 are nucleotides,
- a non-oligonucleotide mucosal adjuvant that is not an immune stimulating complex, and
- an antigen,
- wherein the antigen is not encoded in a nucleic acid vector, and wherein the oligonucleotide, the antigen, and the non-oligonucleotide mucosal adjuvant are all administered rectally, intravaginally, or ocularly, to the subject, and a cytokine is not administered to the subject.
A method for inducing a mucosal immune response, comprising:
- administering to a subject in need of a mucosal immune response an effective amount for inducing a mucosal immune response of an oligonucleotide 8 to 100 nucleotides in length, having a sequence including at least the following formula:
- 5′X1X2CGX3X4 3′
- wherein C is unmethylated, wherein X1, X2, X3, and X4 are nucleotides, and
- a viral antigen,
- wherein the antigen is not encoded in a nucleic acid vector, the oligonucleotide and the antigen are both administered vaginally, rectally, intranasally, ocularly, or by inhalation to the subject, and a cytokine and an immune stimulating complex are not administered to the subject.
A method for inducing a mucosal immune response, comprising:
- administering to a subject in need of a mucosal immune response an effective amount for inducing a mucosal immune response of an oligonucleotide 8 to 100 nucleotides in length, having a sequence including at least the following formula:
- 5′X1X2CGX3X4 3′
- wherein C is unmethylated, wherein X1, X2, X3, and X4 are nucleotides, and
- passively exposing the subject to an antigen,
- wherein the antigen is not encoded in a nucleic acid vector, oligonucleotide administration and antigen exposure both occur vaginally, rectally, intranasally, or by inhalation, and a cytokine and an immune stimulating complex are not administered to the subject.
A method for inducing a mucosal immune response, comprising:
- administering to a subject in need of a mucosal immune response an effective amount for inducing a mucosal immune response of an oligonucleotide 8 to 100 nucleotides in length, having a sequence including at least the following formula:
- 5′X1X2CGX3X4 3′
- wherein C is unmethylated, wherein X1, X2, X3, and X4 are nucleotides, and
- an antigen,
- wherein the antigen is not encoded in a nucleic acid vector, the oligonucleotide and the antigen are both administered vaginally, rectally, or ocularly to the subject, and a cytokine and an immune stimulating complex are not administered to the subject.
A method for inducing a mucosal immune response, comprising:
- administering to a subject in need of a mucosal immune response an effective amount for inducing a mucosal immune response of an oligonucleotide 8 to 100 nucleotides in length, having a sequence including at least the following formula:
- 5′X1X2CGX3X4 3′
- wherein C is unmethylated, wherein X1, X2, X3, and X4 are nucleotides, and
- an antigen,
- wherein the antigen is not encoded in a nucleic acid vector and is not a Streptococcus pneumoniae antigen, the oligonucleotide and the antigen are both administered intranasally or by inhalation to the subject, and a cytokine and an immune stimulating complex are not administered to the subject.
A method for inducing a mucosal immune response, comprising
- mucosally administering to a subject an oligonucleotide 8 to 100 nucleotides in length and comprising 5′X1X2CGX3X4 3′ wherein C is unmethylated and X1, X2, X3, and X4 are nucleotides, and an antigen that is not encoded in a nucleic acid vector, and
- systemically administering to the subject the antigen.
A method for inducing an immune response, comprising
- systemically administering to a subject, as a priming dose, an antigen that is not encoded in a nucleic acid vector, and
- mucosally administering to the subject, as a boost dose, an oligonucleotide 8-100 nucleotides in length and comprising 5′X1X2CGX3X4 3′ wherein C is unmethylated and X1, X2, X3, and X4 are nucleotides, and the antigen.
A method for inducing a mucosal immune response in a subject, comprising
- mucosally administering to a subject, as a boost dose, an oligonucleotide 8-100 nucleotides in length and comprising 5′X1X2CGX3X4 3′ wherein C is unmethylated and X1, X2, X3, and X4 are nucleotides, and an antigen that is not encoded by a nucleic acid vector, wherein the subject has received a priming dose of antigen administered systemically.
