Outline of Final Research Achievements |
Bifidobacteria (BI) enhance the host defense of C. elegans and bring the longevity and tolerance to infection. This study was to reveal what is the pattern recognition receptor (PRR) of the worm and which molecule of BI binds to the receptor for the probiotic effects. A gene was found as a putative PRR; knockdown of the gene made the worms susceptible to infection. Further studies are ongoing to examine if the gene codes the product working as a PRR directly and how the gene is involved in the enhancement of host defense.
