Using brain peptide function can inhibit pain

Global SMS According to Xinhua news agency, Tokyo, April 3 (reporter LAN Jianzhong), researchers at Hokkaido University in Japan successfully suppressed the pain caused by pain using the peptide of animal brain endocrine in the experiment, and determined the part of the brain that produced the pain, according to a communique released Wednesday If the rats have experienced pain in a certain place, when they get close to the place again, they will activate the relevant memory and generate painful feelings In the experiment, the research team led by Professor Nan Yawen of the Graduate School of Hokkaido University suppressed the role of corticotropin releasing factor in brain endocrine, or promoted the role of neuropeptide Y The results showed that the rats stayed in the places that had been stimulated by pain for a long time, and they should have avoided here The researchers thus believe that this is because the painful feelings caused by memory in the brain of rats have been successfully suppressed The researchers found that these two peptides only play a role in the type 2 neurons in the bed nucleus of the stria terminalis, which is located in the center of the brain of the mouse, so as to determine that this is where pain occurs They further found that after pain stimulation, the effect of corticotropin releasing factor would be enhanced, causing hyperactivity of the above-mentioned type 2 nerve cells, thus causing pain, while neuropeptide Y could reduce the effect of corticotropin releasing factor, thus inhibiting pain feeling The findings are expected to be used to treat depression caused by long-term pain, or to relieve pain in cancer patients, according to Nan (edit: newsroom)
