The emerging field of gene therapy promises to yield excitingnew treatments for a range of illnesses. Most forms of genetherapy use viral delivery mechanisms, most commonly retroviruses,1and one condition in which this approach has corrected a geneticdefect is X-linked severe combined immunodeficiency (SCID).2X-linked SCID is characterized by the lack of specific typesof lymphocytes (Figure 1A and Figure 1B)7,12 owing to the absenceof the common subunit of the interleukin-2 receptor (IL2Rc).This subunit of the interleukin-2 cytokine receptor is a signalingmolecule that is a component of receptors for several other. . .
