The effects of carrageenans (CGNs) on the host defense mechanisms of macrophages against Salmonella infection were examined in vitro by using macrophage-like J774.1 cells. Iota-CGN reduced the Salmonella-binding and phagocytotic activities of J774.1 cells, but it increased the killing activity of the cells. Kappa-CGN increased the binding activity, but reduced the killing ability. CGNs would affect the host defense mechanisms by modulating the macrophage functions.
