For example, to reverse disease caused by genetic damage, researchers can isolate normal DNA and package it into a vector – a molecular delivery vehicle usually made from a disabled virus. The vector is then used to infect a target cell, usually from a tissue affected by the illness, such as liver or lung cells. The vector unloads its DNA cargo, which then begins producing the missing protein and restores the cell to normal.
