What is the purpose of the virome?


The virome, which encompasses the collection of viruses present in and on the human body, plays several important roles in human health and evolution:

  1. Adaptation and Survival: According to , the virome facilitates adaptation and resilience. It helps humans and other organisms to adapt to environmental changes and stressors, which enhances survival. During periods of significant stress, such as climate changes or catastrophic events, the virome aids in the creation of new genetic variations, contributing to biodiversity and improved adaptive capacities 1 2.

  2. Genomic Diversity: The virome contributes to the genetic makeup of organisms. For instance, Dr. Bush mentions that over 50% of the human genome consists of viral genetic material, some of which play crucial roles in resilience and adaptability. This integration of viral genes into the genome is essential for evolutionary processes and the development of complex life forms 1 2.

  3. Immune System Development: The virome is fundamental in the development of the immune system. Shawn Stevenson highlights that our immune system evolved in the presence of viruses and requires them for its function. He also mentions that about 8% of the human genome is composed of endogenous retroviruses, which are viruses that have integrated into our DNA 3.

    The Virome's Role

    Dr. Zach Bush discusses the virome's purpose in our survival and adaptation, highlighting the importance of genomic insertions and how they contribute to our resilience and dominance on the planet.

  4. Global Biological Communication: Viruses act as a communication network for genetic information among living organisms. This communication helps in the transfer of beneficial genetic material and in the adaptation of organisms to new environments 2.

These insights underline the essential role of the virome in health, adaptation, and evolution, and emphasize the interconnected nature of all life forms through shared viral genetic material.
