In vivo destruction of canine lymphoma mediated by murine monoclonal antibodies

In Vivo

Abstract

The effect of murine anti-canine lymphoma monoclonal antibodies (MAbs) on tumor cell lysis by thioglycolate activated murine macrophages in vitro and tumor growth inhibition in athymic mice was studied. All IgG1 and IgG2a MAbs tested were able to promote specific destruction of canine lymphoma 17-71 cell line by activated macrophages. A correlation between higher ADCC activity and MAb isotype was not clearly evident. In vivo IgG2a and IgG1 MAbs inhibited the growth of canine lymphoma. These results suggest that MAbs of IgG type have potential in immunotherapy of dogs with lymphoma since they have high tumoricidal activity in vivo.

Antibody-Dependent Cell Cytotoxicity

Antibody-dependent cellular toxicity refers to the lysis of a target cell by a non-sensitized effector cell of the immune system as a result of antibodies binding to the target cell membrane and engaging the Fc receptors on the immune effector cells.
