U.S.A. develops a nanometer particle and helps to treat the drug addiction
The American scientist develops a nanometer particle recently, can be used for carrying the particular ribonucleic acid (RNA) The chain, close a gene related to drug addiction of brain, this will contribute to developing the new treatment which will treat the drug addiction.
According to U.S.A.>The network edition reports on the 26th, the past research had already found, a kind of brain protein called DARPP 32 played a key role. The especially designed RNA chain can interfere with the relevant gene, prevents this protein from secreting, so contribute to treating the drug addiction, but lack the safe and effective method to transport RNA chain to the positions needed.
The scientist of the branch school in Buffalo of the New York State University of U.S.A. says, they design the nanometer particle of a kind of pole, can be regarded as " L The means of transport " R Carry RNA chain required to treat, the protective screen while organizing through blood and brain enters the brain cell.
The experiment shows, RNA chain carried on this kind of nanometer particle, 40% can cross the blood brain protective screen, efficiency is improved greatly than the past method.
It is reported, utilize this kind of nanometer particle to carry other RNA chains, can treat Parkinson's disease, cancer and some nerve diseases. Some scientists of this research group will also try to treat AIDS, dementia and asthma,etc. by this kind of method.
