Effects of a Specific Inhibitor of HIV Proteinase (Ro 31-8959) on Virus Maturation in a Chronically Infected Promonocytic Cell Line (U1)
The human immunodeficiency virus (HIV) proteinase inhibitor Ro 31-8959 prevents the maturation of virus in phorbol 12-myristate 13-acetate (PMA)-stimulated U1 cells, a chronically infected promonocytic cell line. Inhibition of both the morphological maturation of virions and the enzymic processing o...

| description | The human immunodeficiency virus (HIV) proteinase inhibitor Ro 31-8959 prevents the maturation of virus in phorbol 12-myristate 13-acetate (PMA)-stimulated U1 cells, a chronically infected promonocytic cell line. Inhibition of both the morphological maturation of virions and the enzymic processing of gag polyprotein (p56) to produce capsid protein p24 was demonstrated at nanomolar concentrations of the compound. Furthermore, prolonged inhibition of the processing of p56 antigen was confirmed in pulse-chase experiments. The conclusion is that Ro 31-8959 can inhibit production of mature virions in a promonocyte cell line which is infected chronically/latently with HIV. |
