Study suggests involvement of herpesviruses in Alzheimer's development

Individuals with Alzheimer's disease had up to twofold higher levels of human herpesviruses 6A and 7 in their brains, compared with those without Alzheimer's, with virus-host interactions having various overlaps with Alzheimer's-related genes, and Alzheimer's pathology was affected by genes, gene transcriptions and several virus proteins, researchers reported in Neuron. The findings may help determine virus biomarkers in the brain that may boost Alzheimer's diagnosis, said researcher Joel Dudley.
