Proteins in HIV spread infection
Proteins in HIV spread infection The AIDS virus uses groups of proteins called
proteasomes to assemble and spread new viral particles. In test

infection by 98 percent. However, it is not known if protease
inhibitors would work in humans, and it will be months or years
before human trials are considered. NOVEMBER 27, 2000
