Gene therapy is a promising technique for improving health in later life. The idea is to influence genes that play a role in ageing so that cells function better. Despite these possibilities, gene therapy for old age is not yet widely available. This is mainly due to problems with the safe and effective administration of the therapy to various organs.
Genes determine the production of proteins in our body, and this production changes with age. Some proteins accelerate ageing processes. Gene therapy can reduce these harmful proteins or, conversely, increase proteins that counteract ageing. Although the technology has existed for decades, delivering gene therapies precisely and safely into the body remains difficult.
Currently, researchers are focusing mainly on treatments in which genes are altered in small areas, such as specific parts of the brain or fat cells. This approach is more manageable and avoids major risks. However, it is not yet possible to reach the entire body with a single treatment without adverse side effects.
In addition, partial epigenetic reprogramming is being looked into. This is a way to rejuvenate gene activity in cells by making changes to the structure of the DNA. This method is also in its infancy and faces similar objections regarding administration and safety.
Research into gene therapy for ageing is important because it can help us stay healthy and vital for longer. Due to current limitations, it is still primarily a promising research area for the future.
