Humans as holobionts: implications for prevention and therapy

Area of Science:

• Microbiology
• Human Health
• Systems Biology

Background:

• The human gut microbiota plays a crucial role in maintaining health.
• A complex, interdependent relationship exists between the gut microbiota and the host.
• Homeostasis, a stable equilibrium, is vital for health, but perturbations can lead to disease states.

Purpose of the Study:

• To emphasize the necessity of a holistic view of the gut microbiota-host association.
• To explore how disruptions in microbiota-host equilibrium contribute to chronic diseases.
• To advocate for integrated approaches in preventing and treating diseases linked to the gut microbiota.

Main Methods:

• Conceptual review of microbiota-host interactions.
• Analysis of the shift from healthy equilibrium to pre-disease and disease states.
• Systems biology perspective on feedback loops maintaining stable states.

Main Results:

• Perturbations in the microbiota-host equilibrium can lead to alternative stable states, including pre-disease and chronic disease states.
• A significant portion of the Western population may exist in a pre-disease state due to this imbalance.
• Chronic diseases like IBD and obesity are presented as distinct stable states, making them difficult to cure.

Conclusions:

• The gut microbiota-host association is a dynamic system with feedback loops.
• Integrated therapeutic strategies targeting both host and microbiota are essential for managing and preventing chronic diseases.
• Understanding these stable states is key to developing effective interventions for gut health.
