He has projects for delivering corrective genes to the liver, the eye and the lung as well as to muscle cells.

Most gene therapy trials depend on viruses to deliver corrective genes to human cells.

IN the six years since the first corrective genes were injected into the first patient, gene therapy has exploded.

He was part of a group of 18 patients who were being tested with different doses of a virus carrying a corrective gene.

To get corrective genes into cells, gene therapists have to rely on viruses, which specialize in exactly this task.

A high dose of adenovirus carrying a corrective gene was injected into his liver.

Mr. Gelsinger died after an overwhelming immune reaction to an infusion of corrective genes.

It involved an infusion of corrective genes, encased in a weakened cold virus, adenovirus.

The vector is the disabled virus used by gene therapists to insert corrective genes into human cells.

The patient, now 5, was given her first infusion of corrective genes in 1996 and was slowly weaned from the drug.
