IgE antibodies and mast cells play critical roles in the establishment of
allergic responses to food antigens. Curcumin, the active ingredient of the curry
spice turmeric, has anti-inflammatory properties, and thus may have the capacity
to regulate Th2 cells and mucosal mast cell function during allergic responses.
We assessed whether curcumin ingestion during oral allergen exposure can modulate
the development of food allergy using a murine model of ovalbumin (OVA)-induced
intestinal anaphylaxis. Herein, we demonstrate that frequent ingestion of
curcumin during oral OVA exposure inhibits the development of mastocytosis and
intestinal anaphylaxis in OVA-challenged allergic mice. Intragastric (i.g.)
exposure to OVA in sensitized BALB/c mice induced a robust IgE-mediated response
accompanied by enhanced OVA-IgE levels, intestinal mastocytosis, elevated serum
mMCP-1, and acute diarrhea. In contrast, mice exposed to oral curcumin throughout
the experimental regimen appeared to be normal and did not exhibit intense
allergic diarrhea or a significant enhancement of OVA-IgE and intestinal mast
cell expansion and activation. Furthermore, allergic diarrhea, mast cell
activation and expansion, and Th2 responses were also suppressed in mice exposed
to curcumin during the OVA-challenge phase alone, despite the presence of
elevated levels of OVA-IgE, suggesting that curcumin may have a direct
suppressive effect on intestinal mast cell activation and reverse food allergy
symptoms in allergen-sensitized individuals. This was confirmed by observations
that curcumin attenuated the expansion of both adoptively transferred bone
marrow-derived mast cells (BMMCs), and inhibited their survival and activation
during cell culture. Finally, the suppression of intestinal anaphylaxis by
curcumin was directly linked with the inhibition of NF-?B activation in
curcumin-treated allergic mice, and curcumin inhibited the phosphorylation of the
p65 subunit of NF-?B in BMMCs. In summary, our data demonstrates a protective
role for curcumin during allergic responses to food antigens, suggesting that
frequent ingestion of this spice may modulate the outcome of disease in
susceptible individuals.
