Abstract: | A complex of polyadenylic-polyuridylic acids effectively inhibits the in vivo production of immunologic tolerance to human gamma globulin in mice. Moreover, this effect can be obtained only when the polynucleotide complex is given within 4 hr after antigen administration.Reconstitution of irradiated mice with combinations of T and B cells originating from tolerant or previously untreated mice demonstrates that poly A:U is responsible for the adjuvant effect observed. Poly A:U exerts its adjuvant effect primarily upon T cells, while B cells remain essentially uninfluenced by the polynucleotides. |
