CpG ODN 2006 and IL-12 are comparable for priming Th1 lymphocyte and IgG responses in cattle immunized with a rickettsial outer membrane protein in alum

Immunostimulatory oligodeoxynucleotides containing unmethylated CpG dinucleotides (CpG ODN) stimulate IL-12-dependent Th1 dominated cytokine and enhanced IgG responses when co-delivered with antigen to mice. However, the CpG ODN sequences that are optimal for each mammalian species may differ. Previously, we demonstrated that a CpG ODN containing the GTCGTT motif was optimal for stimulating bovine B cell proliferation, and induced IL-6, IL-12...
