NF-κB Regulation by Gut Microbiota Decides Homeostasis or Disease Outcome During Ageing

Area of Science:

• Microbiology
• Immunology
• Gastroenterology

Background:

• Host-microbial interactions are ancient, involving complex communication and feedback loops.
• The gastrointestinal tract is a key site for host-microbial dialogue, crucial for maintaining homeostasis.
• Pattern recognition receptors (PRRs) initiate host responses to microbial signals.

Purpose of the Study:

• To outline the critical role of nuclear factor kappa B (NF-κB) in host responses to microbial cues.
• To explore the involvement of NF-κB in ageing and age-associated diseases.

Main Methods:

• Review of existing literature on host-microbe interactions and NF-κB signaling.
• Analysis of NF-κB's function in maintaining gut homeostasis and its dysregulation in disease.
• Focus on the interplay between NF-κB, microbial recognition, and host transcriptional responses.

Main Results:

• NF-κB is a central regulator in the communication between host and gut microbes.
• NF-κB activity influences the balance between host tolerance and inflammation.
• Ageing impacts NF-κB function, potentially contributing to disease pathogenesis.

Conclusions:

• NF-κB is integral to host-microbe communication and maintaining gut homeostasis.
• Dysregulation of NF-κB signaling is implicated in ageing and associated diseases.
• Understanding NF-κB's role is crucial for developing therapeutic strategies for age-related conditions.
