Immulina, a high-molecular-weight polysaccharide extract from the cyanobacterium() is a potent activator of innate immune cells. On the other hand, it is well documented thatexerts anti-inflammatory effects and showed promising effects with respect to the relief of allergic rhinitis symptoms. Taking into account these findings, we decided to elucidate whether Immulina, and immunLoges(a commercial available multicomponent nutraceutical with Immulinaas a main ingredient) beyond immune-enhancing effects, might also exert inhibitory effects in the induced allergic inflammatory response and on histamine release from RBL-2H3 mast cells. Our findings show that Immulinaand immunLogesinhibited the IgE-antigen complex-induced production of TNF-α, IL-4, leukotrienes and histamine. The compound 48/80 stimulated histamine release in RBL-2H3 cells was also inhibited. Taken together, our results showed that Immulinaand immunLogesexhibit anti-inflammatory properties and inhibited the release of histamine from mast cells.
