Can green tea help treat brain disorder?
A new therapy combining a chemical
commonly found in green tea with another has been found effective in preventing
and destroying amyloids, involved in fatal brain disorders such as Alzheimer’s,
Huntington’s, and Parkinson’s diseases.
Scientists at Boston Biomedical Research
Institute (BBRI) and the University of Pennsylvania suggested that the novel
discovery might ultimately contribute to treatments for these diseases.
"These findings are significant because it is the first time a combination
of specific chemicals has successfully destroyed diverse forms of amyloids at
the same time," Nature magazine quoted Dr Martin Duennwald of BBRI, who
co-led the study with Dr. James Shorter of University of Pennsylvania School of
Medicine, as saying.
Duennwald had previously shown that exposure to chemical EGCG inhibits amyloid
production in yeast. He had also found that DAPH-12, too, inhibits amyloid
production in yeast. In the new study, researchers exposed two different
amyloid structures produced by yeast (e.g., a weak version and a strong
version) to EGCG.
They found that the EGCG effectively dissolved the amyloids in the weaker
version however stronger amyloids were not dissolved and that some transformed
to even stronger versions after exposure to EGCG.
"Our findings are certainly preliminary and we need further work to fully
comprehend the effects of EGCG in combination with other chemicals on amyloids.
Yet, we see our study as a very exciting initial step towards combinatorial
therapies for the treatment of amyloid-based diseases," said Duennwald.
