Dead but not gone: the interplay between the programmed cell death process and surrounding bacteria.

Area of Science:

• Microbiology
• Immunology
• Cell Biology

Background:

• Cell death is crucial for maintaining tissue homeostasis and removing damaged cells.
• Host cell death pathways are well-understood in immunity and tissue repair.
• The interaction between microbial communities and host cell death is less explored.

Purpose of the Study:

• To review recent advances in host-microbe communication during cell death.
• To discuss how bacteria are modulated by, and modulate, cell death phenomena.
• To explore the potential of targeting cell death mechanisms for therapeutic benefit.

Main Methods:

• Literature review of recent advances in host-microbe interactions and cell death.
• Analysis of how bacterial pathogens and commensals respond to host cell death.
• Discussion of the implications for diseases associated with microbiota dysbiosis.

Main Results:

• Host cell death significantly impacts microbial communities, though this is under-researched.
• Bacteria can both induce and be affected by host cell death pathways.
• Modulating host cell death presents a novel therapeutic avenue.

Conclusions:

• The interplay between host cell death and the microbiota is a promising area for novel therapeutic strategies.
• Understanding these interactions can lead to new treatments for inflammatory bowel disease and cancer.
• Targeting host cell death mechanisms may beneficially modulate the microbiota.
