Environmental Toxins Impair Immune System over Multiple Generations

New research shows that maternal exposure to a common and ubiquitous form of industrial pollution can harm the immune system of offspring and that this injury is passed along to subsequent generations, weakening the body’s defenses against infections such as the influenza virus.

New research shows that maternal exposure to a common and ubiquitous form of industrial pollution can harm the immune system of offspring and that this injury is passed along to subsequent generations, weakening the body’s defenses against infections such as the influenza virus.

The study was led by Paige Lawrence, Ph.D., with the University of Rochester Medical Center’s (URMC) Department of Environmental Medicine and appears in the Cell Press journal iScience. The research was conducted in mice, whose immune system function is similar to humans.

“The old adage ‘you are what you eat’ is a touchstone for many aspects of human health,” said Lawrence. “But in terms of the body’s ability to fights off infections, this study suggests that, to a certain extent, you may also be what your great-grandmother ate.”
