| Outline of Final Research Achievements |
To discover novel effector RNAs of Helicobacer pylori, we analyzed H. pylori-coding small RNAs (sRNAs) and identified RNAs having potential to be translocated from bacteria to host cells. Comprehensive RNA-seq data of H. pylori were generated by next generation sequencers, and the expression levels of sRNA were determined by quantitative PCR to identify sRNA candidates. Moreover, some of the sRNAs were specifically condensed in bacterial outer membrane vesicles, indicating that the particular sRNAs possess capacity to be translocated from H. pylori into the host cells.
