This isn’t about basketball or hair management; this is about autoimmunity. It seems that one of the latest cuplrits to be discovered in the search for lupus antagonists is something called the neutrophil extracellular trap(see http://www.jimmunol.org/content/187/1/538.short). Neutophils are the most plentiful disease-fighting cells in the immune system. The role of neutrophils is to attack and kill invading organisms. These highly motivated soldiers in the immune system’s army are willing to commit suicide in order to fulfill their mission. They do this by releasing chemicals between the cells. The chemicals from different neutrophils join together and form a trap, which serves as a kind of net to capture and destroy pathogens. In order to release enough of the deadly material to be effective, the neutrophil has to deplete its own supply and die. It does so willingly.
Unfortunately, this ally of the body, in waging war, sometimes does damage to the very organism it seeks to protect. When the NETs (neutrophil extracelluar traps) are floating around in the bloodstream they can cause inflammation.
The discovery of the role that NETs play in the development of inflammation is very important to understanding the mechanism which precipitates lupus flares. The more researchers understand this process, the closer they get to thwarting the process. Not only may it be possible to design better therapies so that many of the damaging effects of lupus can be avoided; it may also be possible, with an understanding of the role that NETs play in inflammation, to find a cure and maybe even prevent lupus.
