DNA "Catapulting" White Blood Cells

These white blood cells make up 1-3 percent of your immune system and as a way of attacking it's enemies in the bacteria riddled gastrointestinal tract where they live they fling the mitochondrion DNA at their attackers. The way that it works is it catapults it's DNA ensnaring it's victim in a web of DNA and protien. It ejects it's projectiles, not using air but the pressure of fluids and tissues which fire it within one second. Scientists already knew that these little soldiers secreted toxic protein granules when in battle but this is something completly new.“Eosinophils are really the red-headed stepchild of white blood cells,” says study collaborator James Lee of the Mayo Clinic Arizona in Scottsdale. These white blood cells also are the cause for some forms of cancer as some of the chemicals they excret cause colatoral damage, which can lead to some forms of cancer.
