Bacteria use quorum sensing to communicate via autoinducers, enabling collective gene regulation and community behavior. This cell-cell communication is widespread and can be manipulated, impacting bacterial and eukaryotic interactions.

Area of Science:

  • Microbiology
  • Bacterial Communication
  • Molecular Biology

Background:

  • Quorum sensing is a cell-cell communication mechanism used by bacteria.
  • Bacteria use secreted signaling molecules called autoinducers to coordinate gene expression.
  • This collective behavior is essential for processes that are inefficient for individual bacteria.

Purpose of the Study:

  • To summarize the widespread nature and complexity of bacterial quorum sensing.
  • To highlight the role of quorum sensing in bacterial community behavior.
  • To discuss the potential for manipulation of quorum sensing in inter-species interactions.

Main Methods:

  • Review of existing literature on bacterial quorum sensing.
  • Analysis of communication mechanisms within and between bacterial species.

  • Examination of prokaryotic and eukaryotic factors influencing quorum sensing.

    • Main Results:

    • Quorum sensing is a prevalent strategy across bacterial populations.
    • The chemical communication system (lexicon) is complex, involving intra- and inter-species signaling.
    • Mechanisms to enhance or inhibit quorum sensing exist in both prokaryotes and eukaryotes.

    Conclusions:

    • Bacterial quorum sensing is a fundamental process for collective action.
    • The complexity of quorum sensing suggests sophisticated regulatory networks.
    • Manipulation of quorum sensing is likely a common strategy in microbial and host-associated communities.
