Acrolein: blocking antibody formation: pro tumor, anti-allergy

Methods BALB/c mice were nasally sensitized 5 times in biweekly intervals with KLH alone or with KLH in conjunction with acrolein. Airway hyperreactivity was was measured according to change of enhanced pause and KLH-specific anaphylactic reaction was monitored in vivo Levels of specific antibodies as well as cytokine profile of KLH-stimulated splenocytes were analyzed by ELISA. Further, mouse D2F2-tumor cells were grafted to the flanks and tumor growth monitored in mice previously exposed to acrolein or buffer.
