Essex was among the first researchers to link animal and human retroviruses to immunosuppressive disease and determine that HIV could be transmitted through blood and blood products to hemophiliacs and recipients of blood transfusions. With collaborators, he provided evidence that HIV could be transmitted through heterosexual intercourse. In 1984, he identified gp120, a protein on the surface of HIV that provides a basis for diagnostic tests and epidemiologic monitoring. The protein may also serve as a target for potential AIDS drugs and a vaccine. Essex has worked with colleagues and collaborators in Africa and Asia, where they conduct biological, clinical, and epidemiological studies on HIV-1 and HIV-2.
