Abstract

A CpG-oligodeoxynucleotide (CpG-ODN) includes one or more copies of the sequences of GTCGTT, one or more copies of the sequences of GTT and one or more copies of the sequences of TTTT, wherein at least one copy of the sequence of GTCGTT is encoded between the sequence of GTT and the sequence of TTTT. Further, an immune composition containing the CpG-ODN and its use in the preparation of medicaments for inducing an immune response and for the treatment or prevention of a host disease are also provided.

Description

Technical field [0001] The present invention relates to CpG-oligodeoxynucleotide (CpG-ODN), an immune composition containing the same, and a method for inducing an immune response by using the same. Specifically, it relates to a method for inducing a TLR9-activated immune response and / or A TLR-21-activated immune response and CpG-ODN containing GTCGTT fragments, an immune composition containing the same, and a method for inducing these immune responses. Background technique [0002] CpG-oligodeoxynucleotide (CpG-ODN) is a known immunomodulator with potential. It induces inflammatory cytokines and helper T cell 1 (Th1) polarized immune response, leading to co-existence in antigen presenting cells. The performance of stimulating molecules and increased activation of B cells, T cells, natural killer cells, and other immune cells. [0003] Generally, different CpG-ODNs have race-specific activities based on their composition and length. For example, CpG-1826 (SEQ ID NO: 4) containing...
