The anti -tumor effect of a lipid A, OM -174 (lipid portion of LPS) was studied in a model of breast cancer in mice. In vivo, OM- 174 increases the survival of mice whereas in vitro it is not toxic to cancer cells. OM -174 binds to TLR4 immune cells inducing the production of cytokines such as IFNγ. In vitro, the combination of IFNγ to lipid A is cytotoxic. The objective of this thesis is to analyze those molecular mechanisms. We have shown both in vitro and in vivo that the cytotoxicity of the lipid A / IFNγ is dependent of TLR4 and of the receptor for IFNγ, and the NOS II expression. We also showed that the radical species, NO and superoxide anion forming peroxynitrite play a crucial role in this cytotoxicity. The origin of these radical ...
