#Greentea EGCG Exerts a Strong Immunomodulatory Activity, Reserachers Say

Kyle J. Norton

Green tea is found to have a strong immunomodulating effect, affecting the innate and adaptive immune systems, a renowned institute study suggested.

Green tea, a precious drink processes a number of health benefits known to almost everyone in Asia and the Western world. However, as yin in nature herbal medicine or food, long-term injection of large amounts may obstruct the balance of yin-yang, inducing "yin excessive syndrome" or "yang vacuity syndrome" including weakened immunity and painful cases of GERD,... according to traditional Chinese medicine's Yin-Yang theory.

According to the Harvard Medical School, epigallocatechin-3-gallate (EGCG) isolated from green tea expressed a strong effect on T cell functions, including T cell activation, proliferation, differentiation, and production of cytokines.

Injection of the phytochemical in the animal model showed significant effects in regulated T cell dysfunction in the expression of autoimmune inflammatory diseases as well as ameliorated T cell-mediated autoimmune diseases.

Furthermore, in naïve CD4(+) T cells proliferate and differentiate into different effector subsets, green tea EGCG inhibited the pro-inflammatory Th1 and Th17 cells, subsets of Th cells responsible for inducing autoimmunity, thus improving symptoms and reducing the pathology of autoimmune diseases.

Additionally, Dr. Wu D, the lead author said, "(The) protective effect EGCG is associated with the suppressed proliferation of autoreactive T cells, in reduced production of pro-inflammatory cytokines of Th1 and Th17, and increased T cell regulation populations in lymphoid tissues and central nervous system".

Further evaluation of green tea EGCG effect in regulated CD4(+) T helper (Th) subsets Th1, Th9, and Th17 cells conducted by the Tufts University, postulated that the phytochemical impeded Th1, Th9, and Th17 differentiation in exhibited inflammation by prevented IL-6(the pro-inflammatory cytokine)-induced suppression of Treg development.

More importantly, in experimental autoimmune encephalomyelitis (EAE) rats, EGCG improved function of CD4(+) T cellsthe  through modulated the expression of IL-6 induced cytokine(gp130) in response to autoimmune function and cellular response.

Taken together, the green tea process has a strong immunomodulating effect in reduced risk and treatment of autoinflammatory and immune disease, but long-term and large amounts of intake should be taken with care to prevent toxicity.
