Polysaccharides from red algae affect mice immune systems, say scientists

Carrageenans, biologically active polysaccharides isolated from red algae and widely used in the food industry as stabilizers, thickeners, or jelly agents, have an express effect on the immune systems of mice, according to a new study. The research was carried out by scientists from the School of Biomedicine of Far Eastern Federal University (FEFU), Far Eastern Branch of the Russian Academy of Sciences, and Vilnius University.
