Centenarians are extraordinary people who live remarkably long lives, yet they are still heavily affected by old age. Their bodies are often frail and they have a high risk of death from age-related ailments. Even so, studying their biochemistry and immune system can give us valuable insights. This can help us understand which processes are important within ageing.
The immune system protects our body against diseases. As we age, the functioning of the immune system declines, a process known as immunosenescence. This causes vulnerability to infections and can contribute to the development of diseases of ageing. Research into the immune system of centenarians shows that there are clear differences in how their immune system ages.
By realising which characteristics in centenarians make their immune system stronger, scientists are getting new ideas on how we can slow down the ageing process. Increasing attention is being paid to improving immune function in older people, as this plays a key role in healthy ageing. This research can contribute to better treatment methods and preventive measures.
It is important to know that the results from centenarians are not directly applicable to everyone, but they do provide direction on which processes can be tackled as a priority. In this way, science can work step by step towards extending a healthy lifespan, improving the quality of life for older people.
This knowledge about the immune system is therefore important for anyone interested in healthy and active ageing, because a well-functioning immune system is essential for a long and healthy life.
