a final differentiation of unprimed b cells into igm-producing cells induced by b151-trf2 was markedly inhibited by pge2 at physiological concentrations ( around 10 ( -8 ) m ) , whereas b151-trf1/il-5- induced antibody responses of unprimed as well as activated b cells were not affected by pge2 , even at 10 ( -6 ) m .
