Gene therapy may be in its infancy, but great hopes for its potential to treat everything
from cancer to Alzheimer’s to heart disease are forcing it to grow up fast. After two decades
of lab research, gene treatments are increasingly making their way into human clinical trials.
The bulk of research so far has focused on getting a gene to its destination and coaxing it to
turn on once inside a cell. On their own, genes can’t pass through cell membranes, and
much effort has been spent to trick cells into accepting foreign genes. The most efficient
couriers are so-called viral vectors: viruses whose genomes have been swapped out for
therapeutic genes. Like Trojan horses, they slip genes into target cells undetected. But as
scientists are learning, there is no safe way to hijack a virus. The vectors sometimes trigger
immune reactions. And once the genes are inside a cell, there is no way to be sure they will
function as intended. Case in point: a Paris gene therapy trial to treat SCIDs, or the “bubble
boy disease,” restored immune function in nine of 10 patients. But it was later revealed that
two of them had developed leukemia.
What is the main idea of the passage?
After two decades of lab research, gene therapy in humans has been successful in
treating everything from cancer to Alzheimer’s to heart disease.
A lot of research in gene therapy has focused on getting a gene to its destination and
coaxing it to turn on once inside a cell.
Although research has been done on how gene therapy can help treat serious
diseases, such a treatment may cause irreversible side effects and unknown
consequences.
Viral vectors like Trojan horses slip genes into target cells undetected.

Gene therapy is still in its early stages.
Scientists have made significant progress in taking control of viruses that carry
therapeutic genes.
Much effort in gene therapy has been spent to deceive cells into accepting foreign
genes.
