A new study suggests that HIV pushes a specific subset of the CD4+ "helper" T-cell toward more rapid aging by as much as 20 to 30 years over a three-year period. These findings could partially explain why older HIV-positive people progress to AIDS more rapidly than younger ones. They could also explain why younger HIV-positive people develop illnesses more common to older people.
