β-amyloid are plaques found in the brains of Alzheimer patients derived from the amyloid precursor protein (APP) with function in binding to other proteins on the surface of cells.
Green tea, a precious drink processes numbers of health benefit known to almost everyone in Asia and Western world. However, as yin in nature herbal medicine or food, long term injection of large amounts may obstruct the balance of yin-yang, induced "yin excessive syndrome" or "yang vacuity syndrome" including weaken immunity and painful case of GERD,... according to traditional Chinese medicine's Yin-Yang theory.
The differentiation of green tea activities in risk of plagues deposit in certain parts of the brain to induce development and neuropathogenesis of dementia was found to associate to numbers of implication through several mechanisms.
In the study to clarify the effect of green tea Epigallocatechin-3-gallate (EGCG) in inhibited activities of nitrosative as well as oxidative stress in induction of Abeta-cause of damages in neurons and glial cells surround neurons, researchers at the Daegu Haany University found that application of the phytophenols exerts a significant interference in ameliorated the elevation of Abeta-induced by oxidative and/or nitrosative to facilitate cell death through its antioxidant and anti-inflammatory properties.
Further analysis found that green tea bioactive compound reduced activities of Abeta injection in induction of nitrosative stress on BV2 cells caused by increased expression of inducible nitric oxide synthase (iNOS) in production of nitric oxide (NO) and peroxynitrite, in elevated cytotoxicity to precipitate apoptosis, though inhibited reactive nitrogen species act together with reactive oxygen species to establish chain reaction in damage to BV2 cells.
Further more, the bioactive l-theanine also significantly reduced oxidative protein and lipid damage and elevated glutathione levels in the brain, thus reducing macromolecular oxidative damage in improved memory.
Additional study of green tea effect in attenuated accumulation of β-amyloid (Aβ) peptide plaques is a major pathogenic event in Alzheimer's disease (AD) opinionated that in the wild type amyloid precursor protein (APP) transfected (N2a/APP695) cell line, Epigallocatechin gallate (EGCG), a highly active catechin found in green tea, significantly reinforce the activity of nuclear receptor peroxisome proliferator-activated receptor gamma (PPARγ), a regulator of adipocyte differentiation by promoting its mRNA and protein expressions in N2a/APP695 cells, thus attenuated Aβ generation in N2a/APP695 cells in induction of Alzheimer's disease (AD).
Intriguingly, the efficacy of Epigallocatechin gallate (EGCG) in inhibited β-amyloid (Aβ) peptide plaques accumulation was found to be attributed by its antioxidant activity in decreased the expression of pro-apoptotic proteins (Bax, caspase-3) activated by Aβ insults, the activity of the anti-inflammatory agent NF-κB triggered by β-amyloid (Aβ) peptide and inhibited the oxidative stress by decreasing the levels of ROS and MDA and increased the expression of antioxidant enzyme MnSOD.
These results suggest that EGCG may have preventive and/or therapeutic potential to prevent accumulated β-amyloid in initiated neuro degenerative patients by increasing cellular antioxidant defense capacity in inhibited Abeta-mediated oxidative and/or nitrosative stress to induce cell death. Intake of green tea extract should be taken with great care, as overdoses have been reported to cause liver toxicity.
