Pixantrone is an immunesuppressor similar to mitoxantrone but with lower cardiotoxicity. We evaluated the effect of pixantrone on B cells and lymphomononuclear cells in the course of acute EAE. Pixantrone reduced the number of B cells and suppressed myelin basic protein (MBP) specific IgG production. In vitro, pixantrone induced apoptosis of rat B lymphocytes in a way similar to mitoxantrone. In addition, pixantrone inhibited antigen specific and mitogen induced lymphomononuclear cell proliferation, as well as IFN-gamma production, during EAE. These findings suggest a similar mechanism of action for pixantrone and mitoxantrone on the effector function of lymphomonocyte B and T cells.

Abstract

Pixantrone is an immunesuppressor similar to mitoxantrone but with lower cardiotoxicity. We evaluated the effect of pixantrone on B cells and lymphomononuclear cells in the course of acute EAE. Pixantrone reduced the number of B cells and suppressed myelin basic protein (MBP) specific IgG production. In vitro, pixantrone induced apoptosis of rat B lymphocytes in a way similar to mitoxantrone. In addition, pixantrone inhibited antigen specific and mitogen induced lymphomononuclear cell proliferation, as well as IFN-gamma production, during EAE. These findings suggest a similar mechanism of action for pixantrone and mitoxantrone on the effector function of lymphomonocyte B and T cells.
