Research Brief: HIV runaway theory refuted by researchers

HIV's effect on white blood cells has been questioned by UK researchers.

They have refuted the long-standing runaway theory of HIV, which says that cells infected by HIV produce more HIV particles which leads to HIV production and cell destruction. The researchers used a mathematical model of the processes by which T-cells are produced and eliminated to show that if the runaway theory was correct, then T helper cell numbers would fall to low levels over a number of months, not years (PLOS Medicine Online 2007).
