The findings suggest that in AD, part of what happens in the brain may involve changes in DNA tagging that affect the function of oligodendrocytes, particularly in relation to the buildup of the toxic protein tau.<\/p>\n

Oligodendrocytes are the brain cells that make myelin, the insulation that helps nerve cells communicate. Scientists have theorized that disrupting neuron communication contributes to symptoms for people with AD. Researchers in this study found that nearly all significant methylation changes \u2014 small chemical tags added to DNA that help control when genes are turned on or off \u2014 were linked to the tau protein. This supports the idea that this protein plays a key role in brain cell changes tied to AD.<\/p>\n

\u201cOur team has previously shown that oligodendrocytes are affected in Alzheimer\u2019s and another tau-related disease, progressive supranuclear palsy (PSP),\u201d says the author. \u201cThese new results further highlight that problems in oligodendrocytes and myelin are central to AD. They also point to specific molecular pathways, particularly epigenetic changes, that could be targeted in future therapies.\u201d<\/p>\n

The study results identified new genes that may play a role in AD, including one called LDB3, and confirmed many findings across multiple independent datasets, showing its reliability. The identification of specific genes provides potential targets for future research \u2014 for example, scientists might investigate whether interventions that reverse methylation or support oligodendrocyte health can slow or modify disease progression for patients with AD.

In a study<\/a> published in Nature Communications<\/i>, the researchers have identified specific DNA-level changes in the brains of people with Alzheimer\u2019s disease (AD). Using advanced biological analysis, the team mapped alterations in the brain\u2019s regulatory landscape that may help explain why Alzheimer\u2019s presents and progresses differently from person to person. The findings could also open new avenues for understanding other neurodegenerative diseases.<\/p>\n

Alzheimer\u2019s disease is the most common cause of dementia. Biologically, the disease begins with the formation of protein deposits, known as amyloid plaques, and neurofibrillary tangles in the brain. This causes brain cells to die over time and the brain to shrink. About 6.9 million people in the U.S. age 65 and older live with Alzheimer\u2019s disease. There is no cure, and in advanced stages, complications can result in a significant decline in quality of life and death.<\/p>\n
