Sulfated polysaccharide ι-carrageenan inhibits filovirus GP-mediated infection. Huh7 cells were infected with concentrated HIV pseudotypes bearing EBOV, MARV, or Lassa virus envelope glycoproteins in the presence or absence of different concentrations of ι-carrageenan. Results are expressed as percentages of no ι-carrageenan and represent the means ±SD for duplicate wells. The results are representative of at least three different experiments. Similar results were observed with 293T cells (data not shown).
