Abstract:
Bacteriophages are enigmatic entities that defy definition. Classically, they are specialist viruses that exclusively parasitize bacterial hosts. Yet this definition becomes limiting when we consider their ubiquity in the body coupled with their vast capacity to directly interact with the mammalian host. While phages certainly do not infect nor replicate within mammalian cells, they do interact with and gain unfettered access to the eukaryotic cell structure. With the growing appreciation for the human virome, coupled with our increased application of phages to patients within clinical settings, the potential impact of phage-mammalian interactions is progressively recognized. In this review, we provide a detailed mechanistic overview of how phages interact with the mammalian cell surface, the processes through which said phages are internalized by the cell, and the intracellular processing and fate of the phages. We then summarize the current state-of-the-field with respect to phage-mammalian interactions and their associations with health and disease states.
Insights
Bacteriophages (phages) interact with mammalian cells despite not infecting them. This review details phage-mammalian cell surface interactions, internalization, and intracellular fate, impacting health and disease.
Area of Science:
- Microbiology
- Virology
- Immunology
Background:
- Bacteriophages (phages) are viruses that infect bacteria.
- Their ubiquity in the human body and interactions with mammalian cells are increasingly recognized.
- The human virome and clinical applications of phages highlight the importance of phage-mammalian interactions.
Purpose of the Study:
- To provide a mechanistic overview of phage-mammalian cell interactions.
- To detail phage internalization processes and intracellular fate.
- To summarize the current understanding of phage-mammalian interactions in health and disease.
Main Methods:
- Literature review of phage-mammalian interactions.
- Mechanistic analysis of cell surface binding and internalization.
- Summary of current research on health and disease associations.
Main Results:
- Phages interact with mammalian cell surfaces.
- Phages can be internalized by mammalian cells through various processes.
- The intracellular fate and biological consequences of these interactions are under investigation.
Conclusions:
- Phage-mammalian interactions are complex and multifaceted.
- Understanding these interactions is crucial given the growing use of phages in clinical settings.
- Further research is needed to elucidate the full impact of phages on mammalian health and disease.
