Inhibition of p24 production by culture of HIV-1 infected PBL in Vif peptides

Treatment	HIV-1 expression, pg p24 per 106 cells
	Donor 1	Donor 2
None	11,000	26,000
Vif21-65	3,300	6,300
Angiotensinongen peptide	11,000	20,000
Ro 31–8959	1,000	3,900

Five to six days after infection by HIV-1/ADA, PBL were exposed to the indicated additions in presence of Sendai virus or to Sendai virus alone and then were cultured with no additions to the culture medium or the indicated additions for 3 days before collection of cells for assay of intracellular p24 and Western blot.
