Abstract

The human immunodeficiency virus type 1 (HIV-1) transactivator (tat) protein produced in one cell activated HIV-1 promoter-directed gene expression in a second cell, provided the cells were in direct contact with one another. This observation suggests that the tat protein produced in HIV-1-infected cells has a physiological effect on neighboring cells.
