AB Eventually, gene therapy may be a valid option for chronic viral
infections, including retroviral infections. Human retroviral diseases
fit two categories: (1) those that result from a monoclonal outgrowth of
a human T-cell leukemia virus type I (HTLV-I)-infected cell, as in the
case of adult T cell leukemia (ATL); and (2) those that appear to result
directly from virus load rather than monoclonal outgrowth--such as
tropical spastic paraparesis/HTLV-I associated myelopathy (TSP/HAM) and
human immunodeficiency virus (HIV)-associated acquired immune deficiency
syndrome (AIDS). For ATL gene therapy, corrective mechanisms directed at
regulatory sequences rather than viral sequences may be most important,
though perhaps anti-tax therapy would be useful. For TSP/HAM and AIDS,
gene therapy directed to control virus replication may be most useful.
For anti-retroviral therapy, one may use dominant negative mutants and a
variety of other approaches that direct toxins or compete out viral
regulatory gene signal sequences. For maximum benefit, such therapy
should be directed to different essential genes (eg gag, pol, env, tat
or rev) involved in the virus replication cycle and utilize different
toxic approaches. A major impediment to the use of gene therapy for AIDS
is our inability to transfect a significant fraction of target cells in
vivo. Except for reconstituted mice, retroviral systems of animals have
been under-utilized as models for gene therapy. Naturally occurring
retroviral diseases of cats, goats, horses, and other species provide
models for future development.
