[Comparative study of interferon production in mice with the graft versus host reaction]

Mice with graft versus host reaction (GVHR) show a decreased production of serum interferon and that produced by the bone marrow and spleen cells and blood leukocytes in vitro upon inoculation with Newcastle disease virus. Interferon induction with lipopolysaccharide of Flexner bacteria resulted in activation of production of serum interferon and that induced in spleen cell and blood leukocyte suspensions. Serum interferon production after administration of poly(I) . poly(C) was similar in mice with GVHR and controls.
