As we grow older, our bodies experience a slowdown not only in physical movement but also at the cellular level. This decline in protein mobility can be linked to the onset of chronic health conditions. Researchers have found that proteins with sticky components on their surface can interact with harmful substances from inflammation and stress, causing them to clump together and move slowly. This sluggishness hinders cell function, leading to the breakdown of essential biological processes associated with aging-related diseases. According to cell biologist Alessandra Dall’Agnese from the Whitehead Institute for Biomedical Research in Cambridge, Massachusetts, this molecular bottleneck could be a key factor contributing to various health issues.
