HIV's secret life in gut revealed

One of the first things HIV does when it first enters the body is mess up the gut. Now, the open access journal PLOS Pathogens reports the first 3D ultra-structural study of the human immunodeficiency virus in a live host.The human gut has the highest concentration of HIV target immune cells, most of which the virus destroys within days of infection. This happens even before a measurable drop of immune CD4 T cells occurs in the bloodstream.
