Herpes e alzheimer 0 1
October 19, HealthDay —There's growing evidence that the herpes virus responsible for cold sores also may cause Alzheimer's disease, a new research paper contends. It's been long known that herpes simplex virus 1 HSV1 can been found in the brains of elderly people with Alzheimer's disease, and research has shown that herpes increases Alzheimer's risk in people genetically predisposed to dementia, said researcher Ruth Itzhaki. Newer data suggest that treating people with antiviral drugs might actually protect them from alzheimer, said Itzhaki, a professor of neuroscience at the University of Manchester in England. Beta amyloid plaques and tangles of tau proteins are two of the hallmarks found in the brains of Alzheimer's patients. But the effect that herpes may have on the brain is not yet fully understood, and it's unlikely that the virus alone can explain all cases of Alzheimer's, said James Hendrix, director of global science initiatives for the Alzheimer's Association. We might lower it somewhat, but I don't think we would eliminate Alzheimer's herpes.
Evidence implies the herpes virus may be a cause of the disease, suggesting that effective and safe alzyeimer alzheimer may be able to treat the disease, perhaps even develop vaccinations against it. Herpes simplex virus type 1 is implicated in the disease, and that it infects most people in infancy then remains dormant in the peripheral nervous system, occasionally stress can activate the virus. It was discovered in many elderly people have HSV1 is present in the brain, and was shown that it confers a strong risk of AD when present in the brain of those who carry APOE4 genes in HSV1 can herpes active in the brain, repeatedly which could lead to cumulative damage.
Could Herpes Virus Play a Role in Alzheimer's?
Like other herpes viruses -- herpes simplex, chickenpox and Epstein Barr virus -- strains 6A and 7 linger dormant in the body and can reactivate later in life. The strains have been linked to encephalitis and other chronic conditions. Dudley and his colleagues stumbled across this possible viral link to Alzheimer's during an analysis intended to find ways that alzheimer used to treat other illnesses could be repurposed for treating the dreaded neurodegenerative disease.
The research team had been herpes and comparing the biological networks that underlie Alzheimer's disease, based on detailed genetic analyses of more than brain tissue samples.
The investigators found that the Alzheimer's disease process is likely affected by a complex series of interactions between viral and human genetics. These models helped explain how the viral genes are operating in context of the host's genes.
To test what they found, the researchers performed further genetic analysis on another brain samples collected by the Mayo Clinic and Rush Alzheimer's Disease Center. In these samples, the scientists saw a persistent increase in human herpes viruses 6A and 7 in the brains of Alzheimer's patients.
