Soluble Fas chimeric molecules block death of PBL from HIV-infected individuals. PBL from uninfected (n = 5) or HIV+ (n = 9) individuals were cultured for 3 days in complete medium at a concentration of 106 cells/mL in duplicate cultures. Cultures were performed in medium alone or in the presence of Fas:Fc or TNFR:Fc (10 μg/mL final concentration) and cell viability assessed.
