Cholesterol selectively enhances in vitro latex-specific IgE production in atopic dermatitis patients with latex allergy
Effect of cholesterol on in vitro latex-specific IgE production by mononuclear cells from atopic dermatitis patients with latex allergy. Cholesterol enhanced latex-specific IgE production in a dose-dependent fashion, and maximal enhancement was achieved at 1 microg/ml. In contrast, cholesterol had no effect on latex -specific IgA or IgG4 production. Study for cytokine production revealed that cholesterol decreased latex-induced production of IFN-gamma and IL-12, while it increased latex-induced production of IL-4, IL-10 and IL-13. These results indicate that cholesterol skews cytokine pattern toward Th2 type. Collectively, cholesterol may increase allergen-specific IgE production, which may in turn aggravate allergic symptoms.
