HMI Discovery Opens New Targets for Antiviral Drugs

NEW YORK – July 26, 2018 Researchers at the Human Microbiology Institute (HMI) and Tetz Laboratories have discovered thousands of prion-like domains in human viruses.

That discovery will form the basis of research that opens new ways of viral pathogenicity. The HMI research also suggests new targets for development of new antiviral drugs, and links viruses to diseases such as Alzheimer’s and Parkinson’s.

The research by HMI scientists George Tetz and Victor Tetz, was published this month in Nature’s Scientific Reports. In the paper, George and Victor discuss the discovery of over 2,600 proteins possessing prion-like structures across viruses.

“What they have discovered are new possible targets that can be used for the development of novel antiviral drugs, which could have huge implications in how we treat and fight a whole host of diseases,” Casey Maguire, a PhD, assistant professor of neurology at the Massachusetts General Hospital, explained. Maguire thinks the finding of prion-like domains in viral structures represents an important discovery for the field of virology.

Prions are infectious proteins that due to their β-sheet-rich conformation can self-propagate, leading to the accumulation of misfolded proteins in the brain possesses neurotoxic effects and are known to be implicated in neurodegenerative diseases. The reason for the human prions formation remains inconclusive.

The discovery of prions in viral proteins uncovers a previously unknown pathway for the development of diseases associated with protein misfolding. Those illnesses can include Alzheimer’s and Parkinson’s diseases, ataxias and amyotrophic lateral sclerosis

Previous works have shown that viruses play a role in the development of some diseases listed above. The discovery at HMI for the first time proposes that the misfolding of proteins is the previously unknown pathway for these prions to infect humans.

Victor Tetz; a professor of virology, said the research brings the understanding of the viral interactions with human cells to a new level.

“In particular, this explains the previously unknown mechanisms of viral pathogenicity,” Victor said. “We are very excited to advance our discoveries to develop principally novel classes of antiviral drugs linked to these viral proteins.”

About HMI

The Human Microbiology Institute (HMI), founded in 2015 by pioneers in phagobiome research Victor and George Tetz, is an independent, not-for-profit research organization.

HMI performs breakthrough research for the public interest that results in novel translational approaches to medicine. HMI is addressing some of society’s biggest medical challenges and unmet medical needs. Those needs include12

Alzheimer’s disease, Parkinson’s disease, dementia, metabolic disorders, various cancers, age-related infectious diseases, spreading of antibiotic resistance, etc.
