Curry Spice Curcumin And Parkinson's Disease? Protects Against A53T Alpha-synuclein-induced Toxicity 18 Nov 2008 Johns Hopkins Researchers at Neuroscience 2008 - Curcumin, derived from the curry spice turmeric, has strong antioxidant and anti-inflammatory properties. Both oxidative damage - damage caused by oxygen - and inflammation have been implicated in nerve cell death associated with Parkinson's disease. Now, researchers at the Johns Hopkins University School of Medicine have shown in a laboratory model of Parkinson's disease that curcumin does protect cells from dying. To test the protective effects of curcumin, the research team used a Parkinson's disease cell model system. They tested curcumin on nerve-like cells that make a mutant form of the protein alpha-synuclein, called A53T, that clumps together inside of cells to cause harmful biochemical and cellular changes that eventually kill the cells. A53T alpha-synuclein causes 50 percent of untreated cells to die, whereas only 19 percent of A53T cells treated with curcumin died. Further research showed that curcumin itself reduces oxidative damage. "These results suggest that curcumin is a potential candidate for inhibiting the oxidative damage that leads to Parkinson's disease," says Wanli Smith, Ph.D., an assistant professor of psychiatry and behavioral sciences at Hopkins. "This common curry spice could be a weapon to protect the brain."

However, it is not clear whether curcumin acts directly as an antioxidant in vivo. Due to its limited oral bioavailability in humans (see Metabolism and Bioavailability above), plasma and tissue curcumin concentrations are likely to be much lower than that of other fat-soluble antioxidants, such as alpha-tocopherol (vitamin E). However, the finding that 7 days of oral curcumin supplementation (3.6 g/day) decreased the number of oxidative DNA adducts in malignant colorectal tissue suggests that curcumin taken orally may reach sufficient concentrations in the gastrointestinal tract to inhibit oxidative DNA damage (7). In addition to direct antioxidant activity, curcumin may function indirectly as an antioxidant by inhibiting the activity of inflammatory enzymes or by enhancing the synthesis of glutathione, an important intracellular antioxidant (see below). http://lpi.oregonstate.edu/infocente...cals/curcumin/

curcumin is a Nrf2 inducer, as are sulphorphanes (of which brocco sprouts are the most potent). Alpha lipoic acid positively affects Nrf2 upregulation. and Deprenyl has been shown in cell models to upregulate Nrf2

Much as I love the food, that's a lot of curry! And what's the scuttlebutt about needing some form of pepper to properly metabolize the curcumin? Jon |

A compound from black pepper called piperine or bioperine increases the amount you absorb greatly. It also increases absorption of other things as well. Such as PD drugs as I have discovered over the last two weeks. I find that to be a boon. Just be ready to adjust your doses or spacing as needed.

dear all,
I take the "Now Brand" - I do not sell it - or am I suggesting that anyone take what I take ... however according to the label it reads: Curcumin is the major component of Turmeric (Curcuma longa L.) and extensive scientific research on Curcumin has demonstrated its potent antioxidant properties. Through its antioxidant mechanisms, Curcumin supports colon health, exerts neuroprotective activity and helps maintain a healthy cardiovascular system. more info @ http://www.nowfoods.com/index.php?ac...l&item_id=2792

Piperine physiologically acts like an MAO-B inhibitor. Be careful when taking a curcumin preparation which includes this vehicle if you take an MAO inhibitor.

the curcumin effects are very promising. Here is another: on GI inflammation: http://www.ncbi.nlm.nih.gov/pubmed/1...ubmed_RVDocSum I am trying to find the preparation used for the studies NCB-02... I found this as far as dose.. http://www.ingentaconnect.com/conten...00004/art00004 But I wonder if an enhancing substance is included in the prep? Anyone know? I just found this: http://www.lef.org/magazine/mag2007/...urcumin_01.htm (without piperine) and here it is: http://www.epic4health.com/cuenbicu.html I've been using Curcumin for almost a month, for my arthritis. (I stopped my SAMe for comparison) So far so good. I have not had a relapse which I typically did when I tried to stop SAMe in the past. I am interested in the endothelial actions of curcumin for myself, to perhaps lower C-reactive protein, which I will have tested in 3 months. I am going to try this version I just found! I have used Epic4health before. Their carnitine fumarate was helpful to me in the past. So I know they are a reliable company. I do not see Bioperine listed as an ingredient! I just found a double strength 500mg curcumin gel at the above website...and ordered 2 of them! That is a 4 months supply for me, and came to $49.00. Not bad!
