Primate Immunity Pot Luck

A study done in 2010 shows that humans are more susceptible to some various than non-human primates. This finding explains where there are some diseases that can only effect humans. One example in with HIV. Humans see worse effects than chimpanzees do in terms of HIV. WHat I found to be most interesting is the fact that this infection actually originated in non-human primates. This idea could show the possibility that evolution could help lead to a cure or future disappearance of such disease. While the 'core' response was the same throughout the three species used in this example, the regulatory response was shown to be different. This difference shows that there must have been some adaptation in certain primates that was not transferred to different species through evolution.
