Mast cells are unique immune cells involved in allergic reactions, but also in immunity and inflammation. Interleukin 37 (IL-37) has emerged as an important regulatory cytokine with ability to inhibit immune and inflammatory processes. IL-37 is made primarily by macrophages upon activation of toll-like receptors (TLR) leading to generation of mature IL-37 via the action of caspase 1. In this review, we advance the premise that mast cells could regulate the anti-inflammatory activity of the IL-37 via their secretion of heparin and tryptase. Extracellular IL-37 could either dimerize in the presence of heparin and lose biological activity, or be acted upon by proteases that can generate even more biologically active IL-37 forms. Molecules that could selectively inhibit the secretion of mast cell mediators may, therefore, be used together with IL-37 as novel therapeutic agents.

A phthalide, levistolide A (1), and six coumarins, demethylsuberosin (2), fraxetin (3), (-)-marmesinin (4), 3'( S)- O-β-D-glucopyranosyl-3’,4'-dihydroxanthyletin (5), 3'( R)- O-β-D-glucopyranosyl-3’,4'-dihydroxanthyletin (6), and isopraeroside IV (7) were isolated from the methanolic extract of the roots of Angelica tenuissima Nakai. Their chemical structures were confirmed by comparing spectroscopic and reported data. All seven compounds were isolated for the first time from this plant source. The anti-allergic activities of compounds 1-7 were examined using human mast cells, and compounds 1-3 at 10 μM potently suppressed IL-6 expression and inhibited histamine release from human mast cells by more than 30%.
