Air & Asthma: Pollution Changing Our DNA?
Reported October 15, 2011
(Ivanhoe Newswire) --Between 2001 and 2009 the number of
people diagnosed with asthma grew by 4.3 million people.
While it’s no secret that pollution could trigger
attacks, new research shows dirty air could be doing
more than making your symptoms worse but could have
What triggers your asthma?
“Pollution in our air,” one woman told Ivanhoe.
“Certain foods can, lot of times the change in weather,”
Ian Rideaux, an asthma sufferer told Ivanhoe.
“Particles will really get down into my lungs and I can
really feel the tightness,” Kathy Serrahn, an asthma
sufferer told Ivanhoe.
Asthma has more than 24 million Americans feeling fresh
out of breath.
“Every breath that I took it was wheeze and it kept on
getting worse,” Serrahn explained.
For people like Serrahn it all traces back to one
thing…pollution. But the latest research out of Stanford
University may have millions of sufferers reaching for
their inhalers. Researchers found that dirty air doesn’t
just pollute our lungs, but that it has long-lasting
effects on our DNA! Air pollution reduces the immune
system’s T cells –or---T Regs in the body.
“If you have lower amounts of the cell or the cell
doesn’t function or the function is impaired in any way
we think that it leads to a higher rate of asthma and a
more severe state of asthma,” Kari Nadeau M.D., Ph.D.,
Assistant professor of pediatrics at Stanford University
School of Medicine told Ivanhoe.
T Regs help block autoimmune disorders like lupus, type
1 diabetes, and celiac disease. Altering these cells
--could mean altering your entire immune system. Your
chemically altered DNA can also be passed on!
“When mothers were exposed to it, it caused changes in
the DNA of the children born to those mothers,” Dr.
While experts are still working to see if the DNA can be
reversed --they suggest finding ways to manage.
“Eat the right food eat a healthy diet and take their
vitamins. I think that just builds a good immune
system,” Dr. Nadeau added.
“When it’s an air quality alert I usually just don’t go
outside,” Serrahn concluded.

Researchers say while there are no medications to
permanently reverse DNA changes, they want to find out
if it can be reversed by simply moving to a less
