health π¬ Lead exposure messes with brain cell waste system
Scientists at ICMR-NIN in Hyderabad studied how lead and Alzheimer's-related amyloid-beta peptides affect human nerve cells. They found that lead or AΞ² peptides individually damaged the cells' waste-clearing lysosomes. However, when exposed together, the disruption was much greater, reducing cell survival and damaging lysosomal structure. These results suggest environmental lead exposure could worsen the cellular stress from amyloid-beta. This research emphasizes the link between environmental pollutants and brain health.
