Researchers from Calgary University, Canada, have infected macaque monkeys with feline immunodeficiency virus (FIV). Blood was taken from the macaques, and then injected back into them after being infected with FIV. The macaques suffered a drop in CD4 immune cells, and lost weight. One macaque that initially recovered fell ill again following injection with tetanus toxoid, which sets of latent infections. Usage of FIV and other lentiviruses in gene therapy should be reconsidered, the researchers argue.
