Not even the devil could have designed a virus as fiendish as HIV. Clear it out of the bloodstream and it hides in the lymph nodes. Banish it from the lymph nodes and it lurks in the brain. And even if it could be eradicated from the brain, it could still be found cradled among the chromosomes of a few quiescent immune cells, ready to pounce again after the hunters have gone away.

And yet. And yet the prospect of salvation for people with AIDS seems closer than ever before. Since last November, almost 15 years after the first reported AIDS cases, the U.S. Food and Drug Administration has approved five new drugs that when taken in various combinations with the old standby, azt, have given new life to thousands of desperately ill people. This past summer, researchers isolated a gene that appears to protect some people from HIV infection–even after repeated exposure–and could lead to new genetic therapies against AIDS. Experiments being conducted this fall may tell doctors whether they can hit the virus hard enough and early enough in its infectious cycle to eliminate it from the body altogether. When the medical historians of the 21st century write the chronicles of AIDS, 1996 could stand out as the year the tide finally turned against HIV.

There is still a long way to go. The new combination-drug therapies cost tens of thousands of dollars a year, putting them out of reach, for now, of all but the wealthiest or best-insured patients. Any long-term solution for AIDS will also have to take into account the estimated 20 million people living outside industrialized countries who are infected with HIV. Most of them cannot afford basic health care let alone high-tech treatments, and most are infected with a different subtype of HIV than those commonly studied in the U.S. and Europe. Nor can the scourge be conquered without a vaccine, even though scientists are still unable to answer a fundamental question: What must such a vaccine accomplish in the body in order to protect it?

Even so, the worst fear–the one that seeded a decade with despair, the foreboding sense that nothing could beat AIDS–has finally been exorcised. If any one person can be credited with having presided over that rite, it is Dr. David Ho of the Aaron Diamond AIDS Research Center in New York City. Starting in the early 1990s, he and others focused on the very first stages of HIV infection, hoping to learn what the body does right in fighting the virus and how to strengthen that response. What Ho and his colleagues have learned has fundamentally changed the way scientists think about HIV.

The old view held that not much happened immediately after HIV gained entry into the body. The virus simply hunkered down inside a few of the immune system’s T cells–the linchpins of the body’s defensive forces–for anywhere from seven to 10 years. Then something, no one knew quite what, spurred the microbial invader to seek out and destroy all the other healthy T cells. It reproduced hundreds of thousands of copies of itself, laying waste to the immune system in the process and rendering its host vulnerable to all sorts of opportunistic infections.

Ho and his team demonstrated that there is no initial dormant phase of the infection. Instead the body and the virus are locked in a pitched battle from the very beginning. Every day the viral intruder produces a billion–yes, a billion–copies of itself, all intent on destruction. And every day the infected person retaliates by producing a billion new immune cells in an effort to stop the onslaught. The main battlefield, however, is not the circulatory system, where doctors had been dutifully looking for HIV, taking blood samples every few months. The big fight occurs in the harder-to-study lymph nodes, where day after day, year after year the body battles the virus to a standstill before finally exhausting its immunological reserves.

The trick to beating HIV, Ho believes, is to try to deliver a fatal blow early on, when HIV has been cornered in the lymph nodes but before it has a chance to infiltrate the brain. The way to do that is to combine the firepower of several different antiviral drugs. Until last year there were not enough different kinds of drugs to test this approach. Then on Dec. 6, 1995, the FDA approved a new medication called saquinavir. One of the so-called protease inhibitors, it attacks the virus at a previously untargeted step in its reproductive process. For the first time, doctors could order up a potent cocktail composed of a protease inhibitor, AZT and another powerful drug called 3TC, which is a chemical cousin of AZT’s.

Physicians tried the combination therapy on their sickest patients first. Not everyone responded or could even tolerate the powerful drugs. But in a number of cases, the therapy seemed to have forced the disease into remission. Even the most sophisticated tests could not find a trace of the virus anywhere in these patients’ bodies. There is always the possibility that the drugs will prove too toxic to be useful for very long, or that HIV may find other hiding places in the body from which it can eventually launch devastating counterattacks. But for the moment it appears that the antiviral cocktail is prolonging the lives of thousands of desperately ill people for several months, and may continue to do so for years. “I think that the emerging picture is that multiple drugs do a lot better,” says Ho. “It’s night and day compared to what we used to see a few years back.”

In fact, the treatment works so well for long-standing infections that Ho and his colleagues are now trying it out on a dozen men who are still in the earliest stages of infection. The scientists hope they will be able to tip the balance far enough in their patients’ favor to eradicate the infection. The plan of attack is straightforward enough: if the cocktail of drugs can prevent the virus from making a billion copies a day, then the men’s immune systems will not have to waste a billion cells a day in defense. Instead their bodies can concentrate on finding the few viral stragglers that manage to evade the drugs.

Some of the men who have now been treated for a year show no trace of HIV in their blood. Ho plans to take biopsies of their lymph nodes sometime this fall to see if the virus is hiding there. If the nodes are clear, he will take a few of them off their medication to see whether HIV bounces back. Even if it does, that would not necessarily signal defeat. “It may be possible that the virus will completely burn itself out after two years of inhibition,” Ho says. “On the other hand, we cannot exclude the possibility that there is a \[reservoir\] of the virus that decays very slowly and is so small that it’s hard for us to measure. Five years from now, they may light up and rekindle the whole process.”

The cocktail approach may also require some other as yet undiscovered drugs to be successful. AIDS researchers know from bitter experience that they cannot pin all their hopes on a single therapeutic tactic–even one as promising as combination-drug treatment. That is why scientists hope to open up another front in the struggle against HIV by attacking it at the genetic level.

For all its diabolical skill at dodging whatever doctors throw at it, HIV has one critical weakness. Because it cannot reproduce on its own, the virus must commandeer some of the body’s cellular machinery to make copies of itself. It does this by inserting some extra genetic instructions into the chromosomes of the cells it attacks, causing them to produce specialized viral proteins. Scientists are trying to figure out how to alter the genetic structure of those hijacked cells so that they do not provide HIV with the proteins it needs to reproduce. Depending on how successful the geneticists’ countersabotage is, they will either force HIV to make defective copies of itself, which will not be able to resist drug treatment, or perhaps frustrate the viral pirates so much that no copies are manufactured at all.

AIDS researchers must still overcome some of the same obstacles that have plagued gene therapy in other areas of research. The experimental vectors–harmless viruses that scientists use to deliver into the body the genetic instructions for making the sham proteins–do not always seek out the right target cells. And once in the right cells, they often fail to find the right spot on the chromosomes to counter HIV’s influence. But geneticists expect to have their answers in the next decade or so. “It’s no longer whether something will happen or not–it’s more a matter of how long it will take,” says Dr. Flossie Wong-Staal, who is leading the gene-therapy approach against HIV at the University of California, San Diego. “I am confident that we will have the right kind of vector to deliver the antiviral genes, and we can induce the right combination of antiviral genes to completely eliminate resistance.”

That conviction got a big boost this past summer when scientists discovered that some exceptionally lucky people are born with their own genetic shield against HIV. Working independently, research teams from the U.S. and Belgium zeroed in on a single protein, called a chemokine, that lodges on the surface of all T cells. The researchers already knew that HIV uses this particular chemokine, variously dubbed CKR-5 or CCR-5, as a gateway into the cell. They knew that CKR-5 does not grant the virus access all by itself. Before it can gain entry, HIV has to dock with another gateway protein called CD-4 at the same time that it attaches to CKR-5\. So the scientists decided to look at the genetic profile of a handful of healthy men who have never been infected with HIV despite repeated exposure to the virus.

They found that the men have a double dose of defective copies of the CKR-5 gene. Because their T cells do not carry the CKR-5 gateway, HIV cannot gain entry, giving the men a natural immunity. No one knows if that protection is absolute, but the results, if confirmed, have broad implications for both gene and drug therapy. “What these patients apparently show is that those genes are not necessary for a person’s health,” says Wong-Staal. “If it’s dispensable for the person but not for the virus, then it’s a terrific finding. You could create a mutant copy of CKR-5 or inhibit its expression or use chemicals to inactivate it.”

Not all the news in the fight against AIDS is good, of course. Researchers have little more than a string of failures to report from the vaccine front. Early in the epidemic, they decided that it was too dangerous to follow the twin paths of traditional vaccine development–treatments based either on inactivated or weakened viruses. There is simply no way to guarantee that the viruses in a vaccine made of inactivated HIV will remain inactive. Similarly, any merely weakened strain of HIV might still overpower the human immune system. Because of the all too likely prospect that the resulting HIV vaccines would cause the very disease they were supposed to prevent, most scientists do not plan to pursue the old-style approach any further.

The first alternative vaccines that researchers came up with were safe, all right; they just didn’t work very well. Called subunit vaccines, they depend on noninfectious pieces of HIV to try to trigger immunity. Unfortunately, it now seems apparent that it takes a whole virus to produce a completely effective immune response.

One possible solution is to engineer genetically a harmless hybrid virus that contains some, but not all, of HIV’s hereditary information. Scientists are now focusing their efforts on the canary pox virus, which causes a rash in birds but not in people. By introducing a few HIV genes into the canary pox virus, the researchers hope to create a new microbe that looks sufficiently like HIV that it will prime the body’s defenses against the more serious threat. In early trials of vaccine preparations that include the canary pox agent, half the human subjects appear to be producing the right kind of immune response, but further tests are needed. “By the turn of the year,” says Dr. Dani Bolognesi at Duke University, “we should be able to tell whether these vaccines are going to be worth pursuing further.”

It now seems clear that there will not be a single breakthrough HIV vaccine on a par with the dramatic polio advances of the 1950s. In fact, it will probably take several generations of vaccine development to come up with even a partially effective preparation. Any future HIV vaccine will also have to counteract all 10 of the known subtypes of HIV found around the world–not to mention any new ones that might mutate into being. The task seems so daunting as to be impossible. And yet.

And yet AIDS researchers have faced these odds before. After nearly two decades of trying, at long last they have seen at least some of their efforts blessed with success.
