We can have a mutant cell which is very similar to human cell, but effective to stop the virus. Or we can create a new Virus killer T cell, that is much fast than the natural one. We can carry our experiments on Tortoises, which are well known for there immunology, or any other species which has stronger cell, that an HIV virus can not infect. Like we use Horses to generate a antidotes to snake venom. We can get a new natural hormone or new type of CD4 cell or something like that, that can help the Human immune system to fight against the VIRUS.
