Air pollution affects cell processes in newborns

Published on September 12, 2023

Imagine that air pollution is like a sneaky intruder that creeps into a house and changes everything. Well, it turns out that air pollution can do something similar to babies even before they are born! Scientists have discovered that when pregnant women are exposed to air pollution, it can cause alterations in proteins that affect how cells function in their babies. One important cell process that gets affected is called autophagy, which is like the cell’s own cleaning crew. Autophagy helps get rid of damaged cells and keeps the body healthy. When the proteins involved in autophagy are altered due to air pollution exposure, it can disrupt this important cleaning process. It’s like having a broken vacuum cleaner or mop in your house. Based on what we know about the harmful effects of air pollution on human health, it’s not surprising that it can have an impact even at such an early stage of life. To learn more about this research and how air pollution affects newborns, feel free to dive into the study link below!

Exposure to air pollution while in the womb is linked to alterations in proteins that can be detected after a baby is born, and which affect cell processes such as autophagy, the ‘self-eating’ of damaged cells that occurs in response to stress.
