Research reveals the human immune system will not distinguish the good green bristlegrass either
Www.xinhuanet.com Paris 8 Cable of the 4th of moon (reporter Li XueMei) The latest research of French researchers indicates, one kind exists in the immune system " L Do not distinguish the good green bristlegrass " R Lymphocyte,it not only not will kill by cancer cell,it instead can protect it.
The research the reason why and Curie university finish jointly with medical research by the intersection of French and State Scientific Research Centre, country. Researchers say, for a long time, scientific circles thinks all the time that a set of cancers exist in the human body " The monitoring system " ,It can discern, eliminate it when the cancer cell is produced, only in the cancer cell once in a while" L Have escaped " R When the immune system monitors, people will suffer from cancer. But the research of French researchers has overthrown this theory, they find, " L The monitoring system " R Unless exist really, but when the cancer cell is produced, it will kill it it,but " L Treat equally without discrimination " R The ground is protected.
Researcher introduce when human immune system activation, two kinds of lymphocytes will arise at the historic moment, a kind of regulating T cell by name, it can discern the human one's own tissue, and protect it; Another kind is called effect T cell, specially stare at and defend coming outside " L The invador " ,And plan to kill it at any time.
Before this, many researchers carried on research to the interdynamic between cancer cell and human immune system, but stage that they observe develop later stage for cancer cell mostly, but French researcher choose cancer cell turn into initial stage as research object. They find, when the cancer cell was just produced, it had no difference with normal cells to express, then" L Ignorant of the fact " R Regulation T cell be will protect up it at onced, and try to block by effect T the involvements of cell. It notice regulating T the existences of the cells, cancer cell whether if still researcher will soon " L Pull the grass up by its roots " .
Researchers say, this discovery has announced the regulating function while the cancer cell grow of T cell, it will help people to develop the new method to treat cancer.
This achievement has already been issued in newest U.S.A. >Have.
