The most exciting feature of the new virus is that it appears to be harmless. In the lab, says Essex, it behaves much like the AIDS virus, infecting the same immunological cells (helper T cells) but without the "dramatic killing action" of its lethal cousin. None of more than 50...
The news of an apparently harmless relative of the AIDS virus was greeted with enthusiasm by other scientists. "The best thing about Max's virus," says Gallo, "is that we can learn why one is pathogenic and the other isn't." By identifying which component of the AIDS virus is...
Late last week research teams in both Gallo's and Haseltine's laboratories revealed that they had already succeeded in tinkering with the AIDS virus and rendering it inactive. They did so by snipping out a gene that enables the virus to replicate with remarkable speed. Without the gene, the...
Unfortunately, there are many obstacles to a truly workable vaccine. Safety is one: even a genetically altered virus could conceivably cause disease. A successful vaccine would have to trigger the production of antibodies that protect the individual against AIDS; most AIDS patients have antibodies that, for some unknown reason, fail...
While medical research into the AIDS virus has proceeded at a phenomenal pace, with doctors making new discoveries every month--or even daily, the prospect of a vaccine or a successful treatment for the disease is still years away. Some facts about AIDS are clear, however. The number of people...
