Figure 8.

IgG and ApoB immune complexes are higher in DKO plasma. IgG levels in peripheral blood were compared at 15 (chow diet) and 26 weeks (15 weeks chow, 11 weeks high‐fat diet). In DKO plasma, all classes of IgG, as well as the concentrations of oxLDL and ApoB‐IgG immune complexes, were elevated, compared to Apoe−/−. For immune complex levels, the assay controls contained either no serum or serum from 26‐week C57/BL6 mice on chow diet. The IC concentration was significantly higher in DKO, compared to Apoe−/−, plasma. Each symbol represents 1 animal. Data are presented as mean±SEM for 12 (Apoe−/−) and 10 (DKO) animals. Significance was determined by independent sample t test. *P<0.05; **P<0.01; **P<0.001. Apo indicates apolipoprotein; DKO, double knockout; IC, immune complexes; IgG, immunoglobulin G; oxLDL, oxidized low‐density lipoprotein.
