Alex K Chen Posted May 10, 2023 Author Report Share Posted May 10, 2023 (edited) https://archive.ph/3qctF Viruses staying in the human body long-term: drivers of aging Quote Friday, May 12th 16:00 - 17:00 Dome This talk by Amy Proal, PhD (PolyBio Research Foundation) will explain how humans are holobionts comprising trillions of microbial and viral organisms whose collective functioning impacts biological signaling. The viral component of this holobiont is referred to as the “human virome.” This virome contains bacteriophage and DNA/RNA viruses. Bacteriophage are viruses that infect bacteria and modulate their activity, and trillions of bacteriophage traffic human tissue and blood at any given moment. However, despite the fact that human and virus biology is intricately connected, certain DNA and RNA virome members such as herpesviruses can contribute to diseases of aging and inflammaging. These viruses have evolved a wide range of mechanisms to directly hijack the activity of the human genome, the human immune response, and human metabolism. For example, the amyloid beta “plaque” that accumulates in the Alzheimer’s brain is now being studied as a peptide that forms in response to viral pathogens in brain tissue[1]. Persistent viruses can also disrupt human signaling directly connected to aging processes. For example, one network analysis uncovered dozens of viruses encoding proteins experimentally demonstrated to interact with proteins from pathways associated with human aging, including cellular senescence[2]. Viral infection can also have profound effects on host cell processes relevant to telomere biology and genome maintenance[3], with human herpesvirus 6 (HHV-6) capable of driving telomere dysfunction by directly integrating into host telomeric DNA. Human virome-driven contributions to aging processes may be rapidly accelerating due to the COVID-19 pandemic. The SARS-CoV-2 virus driving the COVID-19 pandemic is increasingly being studied as a virus capable of long-term persistence in a wide range of human body and brain sites[4]. We may consequently be seeding the human population with yet one more virus that can drive human genome, metabolic and senescence-related dysfunction under certain conditions. It follows that the rapid development of novel antiviral drugs, immunotherapies, and prophylactics could help control virome activity in a manner that should promote human longevity. However, development and use of these novel therapeutics must be done with great transparency. The general public must be fully engaged in the process, so that potential side effects and the “risk-reward” ratios for certain therapeutics can be thoughtfully evaluated and debated. References: 1.

Alex K Chen Posted May 17, 2023 Author Report Share Posted May 17, 2023 Broad Institute of MIT and HarvardBroad Institute of MIT and Harvard 90,727 followers90,727 followers 1d • 1d • New research suggests that centenarians — people who live to be at least 100 — have a diverse collection of viruses in their gut that could help protect them from infectious diseases. Researchers analyzed the viromes, or viral genomes, from 195 individuals from Japan and Sardinia. They found that centenarians had a greater diversity of bacteria and viruses in their guts. The study sheds light on some of the biological pathways that may help centenarians live long, healthy lives and adds to a growing body of evidence showing that the interactions between bacteria, viruses, and fungi in the gut play an important role in preventing age-related conditions.#BroadInstitute #Science #ScienceNews #ScientificResearch #Research Quote Link to comment Share on other sites More sharing options...

Alex K Chen Posted August 17, 2023 Author Report Share Posted August 17, 2023 Quote It appears that our viromes begin to accumulate when we are born. Studies reveal a high diversity of viruses in the infant gut shortly after birth, suggesting that they probably come from the babies’ mothers, some ingested from breast milk. Some of these viruses decline in number as infants grow to weeks or months old; others enter their bodies from the air, water, food and other people. These viruses grow in number and diversity, infecting cells where they will persist for years. Infant viromes are unstable, whereas adult viromes are relatively stable. Anelloviruses, a family of 200 different species, are present in almost everyone as we get older. This mirrors what we observe for bacteria as well.
