Using various constructs expressing a lacZ reporter gene under the control of the intact or three deleted forms of HIV-1 LTR , we obtained evidence that the kappaB regulatory elements located in the U3 region are involved in cell-to-cell activation of HIV-1 LTR .
 ( DNA: HIV-1 LTR, None) , ( DNA: HIV-1 LTR, None) , ( DNA: U3 region, None) , ( DNA: kappaB regulatory elements, None) , ( DNA: lacZ reporter gene, None)
