Research says Alzheimer's disease may be related to herpes virus June 26, 2018 Source: Xinhua News Agency A study shows that the common human herpesvirus may play a role in the development of Alzheimer's disease. If this conclusion is confirmed, it will mean that antiviral drugs are effective in some cases. There is currently no effective treatment for Alzheimer's disease, and the understanding of the pathogenesis is not deep enough. Previous studies have shown that viral infections increase the risk of Alzheimer's disease, but many scholars are skeptical about this because of the small number of samples. According to a recent report by the British magazine New Scientist, researchers at the Mount Sinai Icahn School of Medicine in the United States said they used a sample of multiple brain tissue banks to compare 622 patients with Alzheimer's disease and 322 non- In the brain tissue of the patient, it was found that there were more human herpesviruses of type 6A (HHV-6A) and type 7 (HHV-7) in the brain lesion area, and the number of viruses was related to the degree of dementia. The researchers analyzed genomics, gene transcription, protein and histopathology and found that the herpesvirus gene interacts with multiple human genes, including some genes involved in the risk of Alzheimer's disease, such as the regulation of amyloid precursor proteins. gene. If the amyloid precursor protein changes abnormally, it will produce neurotoxic beta-amyloid, which is a key marker of Alzheimer's disease. The researchers said the new data showed "convincing evidence" that herpes virus is involved in the development of Alzheimer's disease, but not enough to prove a causal relationship between viral activity and initial disease. Herpes virus may be an environmental risk factor. People infected with a specific gene will develop some immune response and increase the risk of Alzheimer's disease in the future. HHV-6A and HHV-7 are very high in the population and usually do not cause any symptoms. Researchers hope to develop appropriate testing tools to identify people who carry these viruses and have other risk factors for Alzheimer's disease.
