Cell signaling pathways in the neuroprotective actions of

Accumulating evidence supports the hypothesis that brain
iron misregulation and oxidative stress (OS), resulting in
reactive oxygen species (ROS) generation from H2O2 and
inflammatory processes, trigger a cascade of events leading
to apoptotic/necrotic cell death in neurodegenerative
disorders, such as Parkinson's (PD), Alzheimer's (AD) and
Huntington's diseases, and amyotrophic lateral sclerosis
(ALS). Thus, novel therapeutic approaches aimed at
neutralization of OS-induced neurotoxicity, support the
application of ROS scavengers, transition metals (e.g. iron
and copper) chelators and non-vitamin natural antioxidant
polyphenols, in monotherapy, or as part of antioxidant
cocktail formulation for these diseases. Both experimental
and epidemiological evidence demonstrate that flavonoid
polyphenols, particularly from green tea and blueberries,
improve age-related cognitive decline and are
neuroprotective in models of PD, AD and cerebral
ischemia/reperfusion injuries. However, recent studies
indicate that the radical scavenger property of green tea
polyphenols is unlikely to be the sole explanation for their
neuroprotective capacity and in fact, a wide spectrum of
cellular signaling events may well account for their
biological actions. In this article, the currently
established mechanisms involved in the beneficial health
action and emerging studies concerning the putative novel
molecular neuroprotective activity of green tea and its
major polyphenol (-)-epigallocatechin-3-gallate (EGCG), will
be reviewed and discussed.

I am a sufferer of parkinsons disease, does this mean
ordinary green tea found in supermarkets or is it special
green tea.

Is this something easily available?

There is a very strong case for links between environmental
poisons, particularly pesticides, and Parkinsons. Studies
have been and are being done right up until and including
the present time. Check it out on pub med. So first, find
out what links you have there, which ones could have
contributed. Then see if there is any way of either getting
them out of you, to whatever extent, or at very least of
ameliorating their effects. First find out the causes! Then
see what can be done about that, preferably asap.

As well, if you are on any meds for it, check out the side
effects of those
- some of them are very unpleasant and yet are dismissed as
being the person's problem, or just ignored.
