Immunological effects of mouse ceruloplasmin.
Mouse ceruloplasmin, the level of which in serum increases on administration of antitumor polysaccharides, was shown to have enhancing effects on the antibody production of mouse spleen cells toward sheep red blood cells and restorative effects on the suppressed mixed lymphocyte reaction of spleen cells of tumor-bearing mice. The proliferation of interleukin-2 dependent cytotoxic T cells and the suppressed concanavalin A response of the tumor bearing mice spleen cells were also enhanced by this serum glycoprotein, weakly but reproducibly. Furthermore, this serum glycoprotein was found to enhance glucose consumption and interleukin-1 production and cytotoxic activities of mouse peritoneal macrophages. These results suggest that mouse ceruloplasmin plays some roles in the natural resistance surveillance against tumors.
