AB The HIV-1 infection of central nervous system, with attendant neuropathy
and dementia, poses a unique challenge for antiviral therapy. For
practical considerations, it is important to define carefully the
precise therapeutic objectives. (1) Is it necessary to inhibit spreading
HIV-1 infection in the central nervous system? (2) What is the role of
inflammatory responses in central nervous system disease during HIV-1
infection? (3) Is there a correlation between pathology and dementia?
(4) Are virions or virus gene products toxic in the central nervous
system? (5) Is there a role for immune suppression and opportunistic
pathogens in AIDS dementia? The development of therapeutic agents for
HIV-1 infection is guided by our knowledge of virus structure, the
function of viral proteins, the interactions with host components, and
detailed features of the virus life cycle. In each case, unique features
of the virus can be identified and established as targets for unique
antiviral compounds. Drugs acting as inhibitors of virus enzymatic
functions are plagued by the rapid development in vivo of drug-resistant
virus variants, although combination or alternating chemotherapeutic
regimens may obviate some of these concerns. Novel approaches to
inhibiting virus are flourishing. In vitro studies show the value of
agents as diverse as molecular decoys for tat activity to efforts to
mutagenize integrated proviruses by modified oligonucleotides that form
triple helices with chromosomal genes. As each particular clinical
situation is better defined, the design and application of these agents
can be refined to inhibit HIV-1 replication and reduce the associated
morbidity.
