why is it so hard for science to fight autoimmune diseases?
In: 14
Autoimmune disease happens when the body’s natural defense system can’t tell the difference between your own cells and foreign cells, causing the body to mistakenly attack normal cells. So it is the immune system working the way it should, but getting the target wrong.
As you can imagine, it is very difficult to stop the immune system from attacking the wrong cells without _also_ keeping it from attacking the right ones. Many of the treatments for autoimmune diseases involve basically wiping out the immune system and hoping that when it “reboots” it gets its targets right again.
