Here we show that 24 h of stimulation with MsST in mouse splenocytes and peritoneal macrophages strongly induces expression of interleukin (IL)-33, a cytokine in the IL-1 superfamily. Other IL-1 superfamily members, including IL-1 alpha, IL-1 beta and IL-18, are down-regulated after 24 h of stimulation of MsST. We also found that MsST-induced IL-33 mRNA expression is inhibited by the suppressive ODN A151, which can inhibit Toll-like receptor 9 (TLR9)-mediated responses. This is the first report to show that IL-33 can be induced by CpG ODNs. The strong induction of IL-33 by MsST suggests that it may be a potential therapeutic ODN for the treatment of inflammatory disease. The presence of a strong CpG ODN in S. thermophilus also suggests that the bacterium may be a good candidate as a starter culture for the development of new physiologically functional foods., Article, BIOCHEMICAL AND BIOPHYSICAL RESEARCH COMMUNICATIONS. 394(1):81-86 (2010)}, pages = {81--86}, title = {CpG oligodeoxynucleotides induce strong up-regulation of interleukin 33 via Toll-like receptor 9}, volume = {394}, year = {2010} }
