Insights
Bacteriophages (phages) are viruses that infect bacteria and can regulate the gut microbiome, influencing cardiometabolic health. Understanding the phageome is crucial for developing phage therapy and fecal viral transplants for these diseases.
Area of Science:
- Microbiology
- Virology
- Human Health
Background:
- Cardiometabolic diseases are a major cause of death in Western countries.
- Risk factors include genetics, lifestyle, diet, and the gut microbiome.
- Bacteriophages (phages), viruses that infect bacteria, significantly influence gut bacterial communities.
Purpose of the Study:
- To introduce the phageome as a key component of the gut microbiome.
- To explore the potential of phage therapy and fecal viral transplants for cardiometabolic diseases.
- To review current research on the phageome's role in cardiometabolic health.
Main Methods:
- Literature review of phageome research in cardiometabolic diseases.
- Discussion of phage therapy and fecal viral transplants.
- Analysis of indirect phageome influence via gut bacteria and metabolites.
Main Results:
- Phages are key regulators of gut bacteria and their activities.
- Phage manipulation of bacteria offers therapeutic potential for cardiometabolic diseases.
- The phageome may indirectly impact cardiometabolic health through microbial metabolites.
Conclusions:
- A deeper understanding of the phageome is necessary for its therapeutic application.
- Phage-based interventions show promise for managing cardiometabolic diseases.
- The gut phageome represents a novel target for improving cardiometabolic health.
Abstract:
Cardiometabolic diseases are leading causes of mortality in Western countries. Well-established risk factors include host genetics, lifestyle, diet, and the gut microbiome. Moreover, gut bacterial communities and their activities can be altered by bacteriophages (also known simply as phages), bacteria-infecting viruses, making these biological entities key regulators of human cardiometabolic health. The manipulation of bacterial populations by phages enables the possibility of using phages in the treatment of cardiometabolic diseases through phage therapy and fecal viral transplants. First, however, a deeper understanding of the role of the phageome in cardiometabolic diseases is required. In this review, we first introduce the phageome as a component of the gut microbiome and discuss fecal viral transplants and phage therapy in relation to cardiometabolic diseases. We then summarize the current state of phageome research in cardiometabolic diseases and propose how the phageome might indirectly influence cardiometabolic health through gut bacteria and their metabolites.

Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...
