TLR Adjuvants

CpG ODN 10101 (ODN 10101; CPG 10101) is a selective agonist targeting TLR9, a synthetic oligodeoxynucleotide modified with phosphate thioester. CpG ODN 10101 activates B cells and plasmacytoid dendritic cells (pDCs), inducing the production of cytokines and chemokines such as interferon-IFN-α, interferon-inducible protein IP-10, and 2'5'-oligoadenylate synthase (2'5'-OAS), regulating innate immunity and promoting Th1 adaptive immune responses. CpG ODN 10101 also possesses antiviral properties and enhances vaccine immunogenicity, making it suitable as an immunomodulator and vaccine adjuvant for vaccine development in chronic hepatitis C and infectious diseases such as melioidosis, pertussis, and respiratory syncytial virus (RSV).

Vidutolimod (CMP-001) is a virus-like particle containing a TLR9 activator. Vidutolimod induces human peripheral blood mononuclear cells to secrete IFNα, and upregulates the gene expression of CXCL10, PDL1, IDO and CD80. Vidutolimod activates TLR9, which in turn triggers plasmacytoid dendritic cell activation, production of IFNγ and TNFα, induction of CXCL10, and recruitment of antitumor T cells. Vidutolimod causes influenza-like symptoms, hypotension and tumor regression, and its activity depends on the presence of anti-Qβ antibodies. Vidutolimod modulates monocyte function, promotes CD4 T cell proliferation, and activates multiple immune cell types in an environment with anti-Qβ antibodies. Vidutolimod prolongs the survival of tumor-bearing mice. Vidutolimod is used in research related to advanced melanoma, head and neck squamous cell carcinoma, and advanced non-small cell lung cancer.

Vidutolimod sodium is a CpG-A oligodeoxynucleotide. Vidutolimod sodium is a Toll-like receptor 9 (TLR9) agonist, which activates plasmacytoid dendritic cells (pDCs) and triggers interferon alpha (IFNα) release, leading to a cascade of anti-tumor immune effects.

ODN 2007 sodium, a class B CpG ODN (oligodeoxynucleotide), is a Toll-like receptor (TLR) ligand. ODN 2007 sodium can be used as an immunomodulator, vaccine adjuvant, and enhance immune responses in mammals, fish, and humans. ODN 2007 sequence: 5'-TCGTCGTTGTCGTTTTGTCGTT-3'.

ODN 2007, a class B CpG ODN (oligodeoxynucleotide), is a Toll-like receptor (TLR) ligand. ODN 2007 can be used as an immunomodulator, vaccine adjuvant, and enhance immune responses in mammals, fish, and humans. ODN 2007 sequence: 5'-TCGTCGTTGTCGTTTTGTCGTT-3'.

C12-TLRa is an ionized adjuvant lipid. C12-TLRa targets TLR7/8 receptors in endosomes. C12-TLRa enhances mRNA delivery as a structural component of LNPs. C12-TLRa enhances innate immune responses. C12-TLRa can be used for the research of SARS-CoV-2 mRNA vaccine.

ODN 2336 sodium is a A-Class CpG ODN (oligodeoxynucleotides), is a potent TLR9 agonist. ODN 2336 sodium induces the production of IFN-α. ODN 2336 sodium up-regulates the expression of IP-10 mRNA and IL-18 mRNA. ODN 2336 sodium can be used as adjuvant of vaccines.

ODN 2336 is a A-Class CpG ODN (oligodeoxynucleotides), is a potent TLR9 agonist. ODN 2336 induces the production of IFN-α. ODN 2336 up-regulates the expression of IP-10 mRNA and IL-18 mRNA. ODN 2336 can be used as adjuvant of vaccines.

FP-18 disodium, a TLR-4 agonist, is a vaccine adjuvant.

HS201 is a nucleotide extract that can be used as a vaccine adjuvant. HS201 can activate Toll-like receptors and trigger Th1 immune responses. HS201 is mainly used in inactivated vaccines for diseases such as foot-and-mouth disease.

4A-MPLA ammonium is an orally active TLR4 agonist. 4A-MPLA ammonium induces TLR4 endocytosis dependent on Cdc42 and galectin-3, triggering TRIF-mediated signaling and sustained IFN-β production. 4A-MPLA ammonium promotes lipid droplet formation, upregulates interferon-stimulated genes and type I IFN signaling genes, downregulates lysosome/phagosome function genes, and modulates tolerogenic dendritic cell function. 4A-MPLA ammonium can be used for the research of colitis.
