Host Genetic Regulation of Stem Cell-Virus Interactions in Human Health

Area of Science:

• Virology
• Stem Cell Biology
• Immunology

Background:

• Interactions between viruses and human stem cells differ from those with differentiated cells.
• These interactions involve heterogeneous intercellular mechanisms and responses to specific infectious agents.
• Understanding these differences holds significant clinical and translational potential.

Purpose of the Study:

• To discuss mechanistic interactions between stem cells and viruses, including entry, replication, and immunomodulation.
• To critically assess models of viral manipulation of stem cell biology.
• To propose new paradigms for stem cell biology, therapeutic interventions, and viral pathogenesis.

Main Methods:

• Review and critical assessment of existing literature on virus-stem cell interactions.
• Analysis of proposed models and hypotheses regarding viral manipulation of stem cell biology.
• Exploration of similarities between stem cells and complex viruses (giant viruses, jumbo phages).

Main Results:

• Viruses exhibit distinct interactions with stem cells affecting phenotypes and human pathophysiology.
• Viruses play a dual role in oncogenesis and oncolysis.
• Emerging viral phenomena and established mechanisms offer new perspectives on viral adaptability and pathogenesis.

Conclusions:

• Further research into virus-stem cell interactions is crucial for understanding viral pathogenesis and developing novel therapeutic strategies.
• New paradigms for stem cell biology and therapeutic interventions can emerge from studying these interactions.
• Exploring similarities with complex viruses can advance our understanding of viral adaptability.
