Scientists have discovered that the APOE2 gene plays an important role in protecting our brain cells against ageing. This gene helps neurons, the nerve cells in the brain, to better repair damage to their DNA. As a result, these cells stay healthy for longer and can function more effectively as we age.
Often, the emphasis regarding APOE genes was placed on their role in fat transport in the body. However, this new study focused on the preservation of DNA in brain cells. This proved to be an unexpected and important way in which the APOE2 gene may contribute to a longer lifespan and better brain health.
The researchers hope that this knowledge can lead to new therapies. By mimicking the protective effect of APOE2, it could become possible to prevent or treat diseases such as Alzheimer's. Alzheimer's is a brain disorder that causes many memory problems, especially in older people.
For anyone wishing to age healthily, understanding how our DNA stays healthy is of great importance. It protects our brains and helps improve quality of life as the years go by.
