Naturally Derived Anti-HIV Polysaccharide Peptide (PSP) Triggers a Toll-Like Receptor 4-Dependent Antiviral Immune Response

<div>PSP decreases viral replication. HIV-1 viral replication was analyzed after 6 days of PSP treatment (200 <i>μ</i>g/ml) by measuring HIV p24 protein in cell supernatants. (a) HIV p24 protein concentration in THP1 cells treated with or without PSP. (b) HIV percentage of inhibition in human PBMCs infected ex vivo and treated with or without PSP from four different healthy subjects.
