ageing is a natural process. Healthy ageing is what we hope and aim for. However there are many compartments and organelles (call them things, stuff) inside our cells that start becoming sloppy! Like a factory that has been running for long and things start to breakdown. Some proteins inside the cells start becoming misfolded by ageing. usually there are check points that assures the quality of proteins that are synthesised. Now if that control is no longer happening efficiently and does not eliminate misfolded proteins, they start accumulating. The more they accumulate the more toxic they get. This is true for the case of neurodegenerative diseases. So in one sentence: yes, sadly by ageing cells start to go wrong, however we hope that we can delay that by our research! 🙂
