The
first cases of AIDS were described on June 5, 1981, here at
UCLA. I started at UCLA in the same year, and have observed
during the ensuing years remarkable success but also notable
failures in our war against this virus. We have deciphered
the complete genetic structure of HIV-1 and all of the proteins
encoded by the HIV-1 genome. The world has two drugs, one
effective and one less effective, with which to fight the
virus: protease inhibitors and reverse transcriptase inhibitors,
respectively.
Yet
looking back, the development of these drugs can largely be
attributed to the understanding of retroviruses and their
replicative machinery developed prior to 1981. As yet, no
drugs has been developed solely on the basis of our enhanced
understanding of HIV-1 genetic structure and specific functions.
The
development of an effective vaccine is the only long-term
solution to the worldwide AIDS epidemic. The
problem is that we understand far less bout the intricate
relationship between HIV-1 and our immune defense system than
we do about the genetic structure of HIV-1 itself. We do not
understand why HIV-1 is so successful at evading our natural
immune defenses. Over the next decade we must develop new
drugs, less expensive drugs, and a vaccine.
