...gene therapy, most of the current "smart bombs," as in the case of Ashanthi DeSilva, are viruses, which by their nature invade cells and deposit their genetic material into the cell nucleus. Researchers have learned how to strip the viruses of their reproductive genes, insert into the viral DNA the beneficial gene they want to deliver, and then let the virus infect a patient's cells. The virus inserts its own now harmless genes, as well as the beneficial one, into the cellular DNA. If all goes well and the gene "expresses" itself, the cell begins producing the needed protein...
...problem is that the altered viruses do not always seek out the target cells and sometimes insert themselves in the wrong place in the cellular DNA. Then too, once in place, the new genes sometimes fail to express themselves. "There are still a few walls to get over," Anderson concedes. He points out that in the initial trial, viruses used for cystic fibrosis, for example, produced an inflammatory response: "So the trials were halted, and another generation of viral vectors was developed. Now we're going to restart the clinical trials with these new-generation vectors," which he thinks will...
