title: Structure and function of human leukemia and AIDS viruses.
abstract: Gene expression directed by the long terminal repeats of human T-lymphotropic viruses is activated in trans by factors present in virus-infected cells. Trans-activation probably plays a major role in stimulating virus production and may also mediate some of the effects of viral infection on the host cell.
