LDLR and atherosclerosis: IFNγ-deficient LDLR−/− mice generated by crossing LDLR−/− mice with IFNγ−/− mice exhibit reduced atherosclerosis (81) whilst LDLR−/− chimeric mice generated by irradiating LDLR−/− mice and transfer of bone marrow from crossing IFNγ−/− mice exhibited aggravated atherosclerosis (82).
