<<The normal enzyme, which is found in all eukaryotes (animals and plants), is a key antioxidant inside cells, changing potentially damaging "superoxide" molecules into less damaging hydrogen peroxide.>> Interesting article. The above was my impression of the role of SOD in playing a "good role" preventing damage during re-vascularization among other things. Have they found that the altered enzyme SOD1 actually has a deleterious effect on the neurons triggering the changes in ALS ? If it is just the "association" then could it be possible that the altered enzyme not been able to carry on the antioxidant effect is what may have a role in the pathologic changes ? In that case blocking the Cu access to SOD1 won't make any difference. I suppose that if they have been working with SOD1 for 10 years, they have enough data to prove that it is indeed a "bad guy" and not an "impaired performer".<g> Bernard
