Japanese researchers observe the small colloid cells in the brain " The working state "
Www.xinhuanet.com Tokyo 4 Cable of the 2nd of moon (reporter Qian Zheng) The small colloid cells in animal's brain repair the special function that the damaged brain organizes, they are known as " Doctor in the brain " . Japanese researchers relied on a kind of special microscope recently, observed these " doctors " for the first time Working state.
The researchers of Japan natural science research institution publish the article and introduce on the network edition of " scientific magazine of nerve " on the 1st, small colloid cells possess the immunological function, they can repair the brain damaged because of stopping up in cerebral apoplexy or brain blood vessel and organize or remove " wastes " in the brain . But, how small colloid cells checked the nerve, fulfilled doctor's duty in the brains of mankind and other animals, all the time nobody has known before this. In this research, researchers utilize a pair of photon laser microscope through improving, success has been carried on in the brain lively and photographed for the first time.
Researcher observe small the intersection of colloid and cell check " palpation " at ordinary times with a frequent one Way come act the part of doctor. Generally, small the intersection of colloid and cell will slack off at all to position that keep in touch each other under the intersection of brain and nerve cell - -Touch health examination suddenly. The frequency checked is probably once for an hour, lasts 5 minutes once. If the neural activity increases, checking the number of times will increase correspondingly. And once the intersection of brain and organization injure, small the intersection of colloid and cell will last one touch and wrap up suddenly while being whole more than hour, touch accurate inspection suddenly like touching.
Researchers predict, while the brain nerve cell is injured and resumed, the intersection of development and stage in brain, little the intersection of colloid and the health examination and accurate to check function to be enormous of cell. They think, utilize the mechanism found this time, the small colloid cells while stimulating the damaged brain to organize through the medicine or biological activity factor, perhaps can accelerate the repair of the brain, or make the brain function resume training more effectively.
