Stimulate and help to maintain the brain function
According to the report of Tokyo (Xinhua) the 11th September ' Reporter Lan JianZhong) Japanese researchers said a few days ago, after they found the area of brain was stimulated, the hormone playing an important role in maintaining the brain function reaches the mechanism of the brain. This discovery has proved at the aspect of member that irritates brain activity to contribute to keeping and improving the brain function.
Hormone " IGF1 " Promote blood vessels to grow and make the function of the nerve cell in the brain nervous system, it mainly produced in the liver. Before this, though scientific circles is known it is transported to the brain by the blood, but how does it pass through " blood brain protective screen " that hormone can't be passed freely It has been a mystery all the time.
In experiment, one of Japan group inject " the IGF1 " into in the blood to the intersection of experiment and mouse jointly Hormone, stimulate the experimental mouse's beard subsequently, in order to activate corresponding cerebral cortex to stand up. The result reveals, in the active area that stands up, this kind of hormone increases. Further discover, " IGF1 " Hormone will be combined with other proteins, form the macromolecule, after the nerve of cerebral cortex is getting active, an enzyme affixed to blood vessel is thereupon activated, and then make this kind of macromolecule decompose, help " IGF1 " Hormone passes the blood brain protective screen.
The research Japan build Professor, university of wave, solicit arrow, clear finishing by the intersection of Tokyo and the intersection of capital and west the intersection of island and strong joint research group made up to wait for someone, assistant of university, Great Britain have.
