Pollution, DNA changes and MS
More about systemic enzymes that are keeping me MS attacks-free - here
The other day, searching for health-related news, I came across such an article:
As source was quite reliable - National Geographic News and I am interested in the subject (multiple sclerosis is autoimmune disorder), I started reading the article carefully:
- Breathing in polluted air may wreak havoc on our DNA, reprogramming genes in as few as three days and causing increased rates of cancer and other diseases
- The same damage may occur in city dwellers exposed to normal air, the researchers say
- ...exposed workers' DNA was damaged...
- Reduced-size gene groups ... have also been found in the blood DNA of lung cancer patients
- You might not have to be a steelworker to sustain this kind of genetic damage...
- ...the same damage can occur in city dwellers—the effects, however, take weeks or months to show up
- For instance, ... previous research shows elderly people ... had DNA damage...
What I am missing is consistency. Some aspects are well documented:
- almost all manufactured chemicals act as pollutants, showing up as xenobiotics, immunotoxins, neurotoxins etc.
- the only mentioned result from exposure to pollutants is lung cancer. They don't mention autoimmune disorders and other pollution-related health problems at all - they mention only "other diseases"
- there is no explanation what happens when DNA has been changed
To my knowledge, the immune system is a full time body guard, recognizing and distinguishing between self and non-self. Next step is to destroy non-self. But what changed DNA really is - self or non-self?
It seems to me, immune system in such situations must be 'confused' - sometimes gets suppressed, sometimes overactive... And as degree of DNA change most probably depends on pollutant (pollutants cocktail), dose and exposure, result is rather unpredictable.
So number of autoimmune disorders (different ways of overactive immune system acting) is already approaching 100. And definitely multiple sclerosis (MS) is among many others.
