Problems solved by technology

[0006] Existing studies have shown that compared with human (h) TLR9 and mouse (m) TLR9, rabbit (rab) TLR9 has a wider ligand recognition profile (ligandrecognition profile) for CpG-ODN with GTCGTT motif or GACGTT motif; However, CpG-ODNs currently developed to activate human or mouse cells have low activity against rabTLR9(14)

Embodiment Construction

[0059] The technical content of the present invention will become apparent through the detailed description of the following embodiments and the illustrations of the related drawings.

[0060] definition

[0061] "About" or "approximately", when used in connection with a measurable numerical variable, refers to the indicated value of the variable and is within the experimental error of the indicated value (for example, a 95% confidence interval for the mean) or within the indicated value. All values ​​of the variable within 10% of , from which the maximum value is taken.

[0062] "Adjuvant" refers to any substance that enhances the humoral or cellular immune response to an antigen. Adjuvants are generally used for two purposes: to delay the release of antigens from the injection site, and to stimulate the immune system.

[0063] "Antibody" refers to an immunoglobulin molecule capable of binding a specific antigen as a result of an immune response to that antigen. Immunoglob...

Abstract

CpG-oligodeoxynucleotides (CpG-ODN), as potent immune stimuli developed for using as adjuvant in different species, are disclosed herein. TLR9 is the cellular receptor for CpG-ODN, and current developed CpG-ODN has low activity to rabbit TLR9. Here, a type of CpG-ODN containing a GACGTT or AACGTT motif in about 11-14 deoxynucleotides was demonstrated to have potent immunostimulatory activity to rabbit TLR9, and capable of boosting a less toxic and potent antibody response in rabbits.

Description

technical field [0001] Cross-references to related applications [0002] This application claims the benefit of US Provisional Application No. 61 / 856,268, filed July 19, 2013, the disclosure of which is hereby incorporated by reference in its entirety. [0003] The present invention relates generally to CpG oligodeoxynucleotides, immune compositions comprising CpG oligodeoxynucleotides, methods for preparing immune compositions and methods for stimulating immune responses, in particular CpG comprising a GACGTT or AACGTT motif Oligodeoxynucleotides, immune compositions comprising CpG oligodeoxynucleotides, methods for preparing the immune compositions, and methods for stimulating TLR9 to activate an immune response. Background technique [0004] CpG oligodeoxynucleotides (CpG-ODNs) are potent immune stimulators, and Toll-like receptor 9 (TLR9) is its cellular receptor (1-5). Several immune effects may result from TLR9 activation by CpG-ODN, including increased T helper (Th)...
