Bee Pollen Components Exert Anti-Allergic Action

Lipid-Soluble Components of Honeybee-Collected Pollen Exert Antiallergic Effect by Inhibiting IgE-Mediated Mast Cell Activation In Vivo
Phytotherapy Research, 2009 Apr 15

It was shown previously that bee-collected pollen (bee pollen, BP), inhibited in vitro murine mast cell activation. This study further analysed the antiallergic effect of BP in vivo by measuring cutaneous mast cell activation using a passive cutaneous anaphylaxis reaction.

Daily oral administration of BP to mice, dose-dependently reduced the cutaneous mast cell activation elicited by IgE and specific antigens. Administration of BP also reduced the plasma concentration of malondialdehyde (MDA), an indicator of lipid peroxidation. The inhibitory effect of BP was mostly in a lipid- but not in water-soluble fraction…

These results first reveal that lipid-soluble components of BP exert an antiallergic action by inhibiting the FcåRI-mediated cutaneous mast cell activation.
