When a cell is infected with HIV, cell membrane fusion results in the formation
of a syncytium to produce a large multinuclear cell. Recently, the author’s laboratory found that 6,6’-bieckol from the brown alga Ecklonia cava notably suppressed syncytium formation in HIV-infected cells, suggesting possible application
in treatments for AIDS (Fig. 8.5).
Several types of antibiotics have been isolated from a marine microorganism
discovered near a wastewater treatment site outlet on the Mediterranean island of
