Green Tea Offers Promising Hope for Skin Disorders
Researchers at Medical College of Georgia studied an animal model for inflammatory skin diseases, which are often characterized by patches of dry, red, flaky skin caused by the inflammation and overproduction of skin cells. The researchers found that those treated with green tea showed slower growth of skin cells and the presence of a gene that regulates the cells' life cycles.
"Psoriasis, an autoimmune disease, causes the skin to become thicker because the growth of skin cells is out of control. In psoriasis, immune cells, which usually protect against infection, instead trigger the release of cytokines, which causes inflammation and the overproduction of skin cells," says Dr. Stephen Hsu, an oral biologist in the MCG School of Dentistry and lead investigator on the study.
Green tea, already shown to contain inflammation, works by regulating the expression of Caspase-14 a protein in genes that regulates the life cycle of a skin cell.
"That marker guides cells by telling them when to differentiate, die off and form a skin barrier. In people with psoriasis, that process is interrupted and the skin cells don’t die before more are created and the resulting lesions form," Dr. Hsu says.
Animal models treated with green tea also showed decreased levels of proliferating cell nuclear antigen, a gene expressed when skin cells multiply. In psoriasis, the gene is over-expressed and speeds production of skin cells.
