The re-engineering of the brain Having explained the concept of re-engineering through gene therapy, it becomes easier to apply this concept to the brain and its disorders. Neurological disorders being targeted by gene therapy involve metabolic disorders, neurodegenerative disorders, and brain tumors. , hypoxanthine-guanine phosphoribosyl-transferase in the Lesch-Nyhan 22 gene therapy for neurological disorders syndrome, or a-L-iduronidase in Hurler's disease). Loss of enzymatic activity leads to disarrangement of neuronal or brain intermediary metabolism in a way that ultimately leads to brain cell death, widespread neurodegeneration, and global neurological dysfunction.

1999), cannot answer all questions relating to human gene therapy. The concepts laid down in the abovequoted foundation of clinical gene therapy while very useful, will require further refinement. They are justified because they are similar to those criteria used in the testing of drugs, and thus are solid enough to be generalized to gene therapy. However, are they sufficient? As W. French Anderson himself discusses: ``The exact definitions of what is `long enough to be effective,' what level is `an appropriate level,' and how much harm is meant by `harm,' are questions for ongoing discussion as more is learned about gene therapy'' (Anderson 1985).

Thus, a liver cell expresses liver proteins, while a neuron expresses neuronal proteins. To date, for the treatment of liver disease, drugs can interfere with the function of liver proteins to achieve a desired therapeutic result. They cannot, however, change the kind of proteins expressed by a liver cell. This means that a liver cell cannot be made to express a nonliver protein, even if the gene encoding such a protein will be present (but not expressed) in the liver cell's genome. Thus, it is conceivable that drugs could be developed that would turn on the expression of nonliver proteins in the liver.
