| Research Abstract |
Gram-negative bacteria produce homoserine lactones for genetic regulation of their own growth rate. In this study, the principal investigator shows the following facts ; (1) Mouse Macrophage-like cell line, RAW264.7, recognizes this molecule. (2) TLR2 and TLR4 that are pattern recognition receptors do not recognize this molecule. (3) By using a homoserine lactone attached biotin, the principal investigator shows that possibly there is a kind of receptor of this molecule on the cell membrane of RAW264.7 cell.
