Our previous study demonstrated that successive electroacupuncture (EA) at ST36 acupoint reduces IgE production in BALB/c mice immunized with 2,4-dinitrophenylated keyhole limpet protein (DNP-KLH) by suppression of the Th2 cell lineage development. Here, we report that pretreatment of phentolamine (α-adrenoceptor antagonist, 10 mg/kg, i.p.) completely blocks the EA-induced suppression of antigen-specific and total IgE levels in serum and IL-4 production in anti-CD3 mAb-activated splenocytes in DNP-KLH immunized mice. The results suggest that α-adrenoceptor play an important role in mediating the suppressive effects of EA on IgE production and Th2 cell response in DNP-KLH immunized mice. © 2007 Elsevier Ireland Ltd.
