Gene transfer to primary chronic granulomatous disease monocytes.
For somatic gene therapy to become a realistic therapeutic strategy for chronic granulomatous disease (CGD), we have to be able to assign the molecular lesion to a specific component of the NADPH oxidase and to confirm that transfer of a functional copy of the corresponding defective gene will result in correction of the cellular defect. We used an adenovirus vector expressing p47phox to transduce monocytes from patients with CGD. We showed by nitroblue-tetrazolium staining that NADPH-oxidase activity was restored to these cells. This technique offers a rapid means for molecular diagnosis. In the short term, this approach may have therapeutic potential.
