A component of DNA that can both stimulate and suppress the immune system, depending on the dosage, may hold hope for treating cancer and infection, Medical College of Georgia researchers say. Low levels of CpG increase inflammation, part of the body's way of eliminating invaders. But high doses block inflammation by increasing expression of the enzyme indoleamine 2,3 dioxygenase, or IDO, an immunosuppressor, the researchers say. (source: my.mcg.edu)
