title: Enhancement of human immunodeficiency virus type 1 replication is not intrinsic to all polyanion-based microbicides.
abstract: Polyanion-based microbicides have been developed to prevent the sexual transmission of human immunodeficiency virus (HIV). Recent data suggest that polyanions have the capacity to enhance HIV type 1 (HIV-1) replication at threshold antiviral concentrations. Evaluation of the microbicide candidates SPL7013 and PRO 2000 revealed no specific enhancement of two CCR5 HIV-1 strains in human peripheral blood mononuclear cells compared to enfuvirtide (Fuzeon). The enhancement effect is likely to be a function of the assay conditions and is not an intrinsic property of these polyanions.
