These days Tulane university pathologist Ivona pandrea and colleagues are working on a very significant issue. Actually, they are prying into an intricate matter to find out why monkeys infected with simian immunodeficiency virus (SIV), which is the primate version of the human immunodeficiency virus do not develop AIDS for years. In this move Ivona pandrea and colleagues analyzed the presence of CCR5-an important marker found on CD4 cells, which are targeted by HIV and SIV, resulting AIDS virus access to those cells. Still, it would be quite difficult to give an opinion on this issue since; this study is just in its beginning. However, taking this study into consideration, it would not be wrong to say that this study may give way to some significant finding, enabling researchers to come out with a portent weapon to fight HIV/AIDS.
