| Outline of Final Research Achievements |
We identified 14 novel anti-inflammatory oligodeoxynucleotide (ODN) from the genomic DNA of Lactobacillus casei using Caco-2 cells. In particular, the ODN 7F (TTTTGCCG) also showed the anti-inflammatory effects in THP-1 cells used as immune cell model and oral administration of 7F ameliorated the severity of colitis in dextran sodium sulfate-induced mouse model of IBD. In addition, the anti-inflammatory effects of 7F were mainly regulated by an increase in heat shock protein (Hsp) 70 expression through TLR9 and Hsp90. Our results suggested that the anti-inflammatory effects of live LAB is dependent on their genomic DNA and ODN identified from LAB genomic DNA possess the potential for treating IBD.
