  1. ncbi Theanine-induced reduction of brain serotonin concentration in rats
    H Yokogoshi
    Laboratory of Nutritional Biochemistry, School of Food and Nutritional Sciences, University of Shizuoka, Japan
    Biosci Biotechnol Biochem 62:816-7. 1998
    ..The use of inhibitors of serotonin metabolism enable us to speculate that theanine reduced serotonin synthesis and also increased serotonin degradation in the brain...
  2. ncbi Effect of theanine, r-glutamylethylamide, on brain monoamines and striatal dopamine release in conscious rats
    H Yokogoshi
    School of Food and Nutritional Sciences, The University of Shizuoka, Yada, Shizuoka, Japan
    Neurochem Res 23:667-73. 1998
    ..These results suggest that theanine might affect the metabolism and/or the release of some neurotransmitters in the brain, such as DA...
  3. ncbi Hypotensive effect of gamma-glutamylmethylamide in spontaneously hypertensive rats
    H Yokogoshi
    Laboratory of Nutritional Biochemistry, School of Food and Nutritional Sciences, University of Shizuoka, Yada, Japan
    Life Sci 62:1065-8. 1998
    ..The same dose of theanine decreased it significantly. GMA administration to SHR reduced the blood pressure significantly, and its degree of hypotensive action was more effective than that by theanine administration...

    T Yamada
    Laboratory of Nutritional Biochemistry, Ministry of Education, Culture, Sports, Science and Technology of Japan, University of Shizuoka, Shizuoka, Japan
    Amino Acids 36:21-7. 2009
    ..Moreover, AMPA receptor antagonist, which regulates glycine and GABA release from glia cells, inhibited these effects of theanine and this result was in agreement with the known inhibitory effect of theanine at AMPA receptors...

    Amino Acids 43:1331-7. 2012
    ..That is to say, GABA might have alleviated the stress induced by the mental tasks. This effect also corresponded with the results of the POMS scores...
