Abstract
HAN and COLLEAGUES, Institution Department of Toxicology, College of Pharmacy, Chungnam National University, Daejeon 305-764, South Korea investigated the anti-allergy potential of P. eryngii extract (PEE) in antigen-stimulated RBL-2H3 mast cells.
Background
Pleurotus eryngii is an edible mushroom native to Europe, the Middle East, and North Africa, and is also grown in parts of Asia.
Methodology
The present study investigated the anti-allergy potential of P. eryngii extract (PEE) in antigen-stimulated RBL-2H3 mast cells.
Results
PEE inhibited allergy markers, including release of hexosaminidase and histamine, in antigen-sensitized RBL-2H3 cells. PEE also suppressed the expression and production of interleukin-4 and reduced antigen-induced NFAT and NF-kappaB transcriptional activity in antigen-sensitized mast cells. Moreover, PEE decreased the levels of proinflammatory cytokines and COX-2 and iNOS expression in antigen-sensitized mast cells. Finally, PEE suppressed antigen-induced signal protein phosphorylation of Lyn, PLCgamma2, PKC, Akt, and MAP kinases.
Conclusion
Taken together, these results suggest that P. eryngii extract may provide insight into the prevention and treatment of allergic and inflammatory diseases.
