1.	Mol Immunol. 2011 Apr;48(8):1027-34. Epub 2011 Feb 16. The immunostimulatory activity of phosphorothioate CpG oligonucleotides is affected by distal sequence changes. Roberts TL, Dunn JA, Sweet MJ, Hume DA, Stacey KJ. Source The University of Queensland, Institute for Molecular Bioscience, Qld 4072, Australia. Tara.Roberts@qimr.edu.au Abstract CpG motifs in bacterial DNA activate innate immune cells via toll like receptor 9 (TLR9). Short synthetic oligodeoxynucleotides (ODN) containing a six base CpG motif can mimic the immunostimulatory activity of bacterial DNA. Phosphorothioate (PS) modification of the backbone of ODN makes them more resistant to nuclease degradation and consequently preferable for therapeutic use. Previous studies have shown that the sequence requirements for PS-ODN to have maximal stimulatory activity are more stringent than for normal phosphodiester (PO) ODN. Here we show small sequence changes distal to the CpG motif can affect the activity of PS-ODN whilst having no effect on the activity of PO-ODN. The addition of terminal dG residues and other minor changes to the potently immunostimulatory PS-ODN 1668S caused delayed signalling. The reduction in immunostimulatory activity of PS-ODN was associated with a delay in the activation of MAP kinases. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.
