A new family tree for African green monkeys implies that an HIV-like virus, simian immunodeficiency virus, or SIV, first infected those monkeys following the lineage split into four species. The new analysis reveals the split occurred about 3 million years back. Previously, researchers thought SIV infected an ancestor of green monkeys prior to the lineage split, much ago longer. ‘Studying SIV assists us learn more about HIV,’ said the paper’s first author Joel Wertheim, a doctoral applicant in the UA department of ecology and evolutionary biology. ‘This finding sheds light on the near future path of HIV evolution.’ All SIVs and HIVs have a common ancestor, added senior author Michael Worobey, a UA assistant professor of ecology and evolutionary biology. The brand new function suggests African green monkeys’ SIVs, or SIVagm, may have shed their virulence a lot more than the millions of years previously thought recently.But the new technology might bypass the poppy, leading to faster and perhaps cheaper methods of creating various kinds of plant-based medicines, based on the Stanford University team. This is just the start, said study senior author Christina Smolke, an associate professor of bioengineering. The methods we created and demonstrate for opioid [narcotic] pain relievers could be adapted to produce many plant-derived compounds to fight cancers, infectious diseases and chronic conditions such as high blood circulation pressure and arthritis.
