Abstract:

Quorum sensing (QS) is a system that bacteria can regulate the gene expression and change the behavior of microbiome by sensing the concentration threshold of specific quorum sensing signal molecules (QSSMs). This regulatory mechanism also plays an important role in the interaction between bacteria and host. The release of QSSMs by bacteria is sensed by the host, which initiates relevant signaling pathways to activate or inhibit gene expression. Current researches have shown that various structures of the host cells, including the cell membrane, cytoplasm, organelles and nucleus are involved in multiple signaling pathways irritated by QSSMs, and mediate relevant host immune responses. In this article, the classification of QSSMs, the research progress of the pathway and effects on hosts were reviewed.

Key words: Bacteria, Host, Quorum sensing, Immunomodulation
