Abstract

In the search for new drugs against human immunodeficiency virus type 1 (HIV-1), the replication of IIIB and BaL strains, and of seven primary isolates from AIDS patients, cultured both in peripheral blood lymphocytes (PBLs) and in monocyte-derived macrophages (MACs), was investigated in the presence of two dermatan sulphate and heparin at 10μg/ml. The three polysaccharides effectively inhibited the replication of IIIB in PBLs and of BaL in MACs, while producing either a slight inhibition or an unexpected large increase in the replication of the seven primary isolates, especially in MAC cultures. In one case, stimulation was found in PBLs and, at lower doses, also with BaL in MACs. Co-receptor use, adaptation to C8166 T cell line, partial sequence of the gp120 V3 loop, variation in positive charge distribution and number of potential glycosylation sites along the V3 loop were assessed for each strain. No explanation could be found for the different susceptibility of the viruses to the polysaccharides. Their presence probably brings about both inhibitory and stimulatory effects, the final outcome depending on the virus, cells and polysaccharide.
