To evaluate the effect of expression of latent membrane protein (LMP) 1 encoded byEpstein-Barr virus (EBV) on Cɛ mRNA expression, mRNA levels were examined by RT-PCRor Northern blot analysis upon transient transfection of LMP1 in the splenocytes derived fromBrown-Norway rats with or without immunization with 2,4-dinitrophenyl-conjugated Ascarissuum antigen. Splenocytes were transfected with LMP1 expression vector, pSG5-LMP1,using lipofection method. Cɛ mRNA levels were considerably increased by transfection with pSG5-LMP1 in the splenocytes derived from the nonimmunized rats; however, Cɛ mRNA levels were decreased in the splenocytes derived from the immunized rats. Cɛ mRNA expression in IgE-producing cells are modulated by LMP1, which might depend onthe differentiation status of B cells upon exposure to allergen
