Yet the discovery of the sick chimps offers what could be a better model for studying pathogenic lentiviruses, a group of viruses including SIV and HIV that are characterized by very long incubation periods.
Once the initial experiments conducted by the researchers confirmed that their approach was working, they injected lentiviruses carrying two well-known oncogenes, H-Ras and Akt, into three separate brain regions of mice lacking one copy of the gene encoding the tumor suppressor p53: the hippocampus, which is involved in learning and memory; the subventricular zone, which lines the brain's fluid-filled cavity; and the cortex, which governs abstract reasoning and symbolic thought in humans.
However, lentiviruses are potentially good vectors for transporting genetic material into neurons because they can infect dividing and non-dividing cells.
