(A-F). Circulating monocytes (A), neutrophils (B), B cells (C), T cells (D) were determined by flow cytometry. (ApoE−/− NC, n=6; MPKCδKO/ApoE−/− NC, n=5; ApoE−/− HFD 4W, n=7; MPKCδKO/ApoE−/− HFD 4W, n= 7; ApoE−/− HFD 16W, n=7; MPKCδKO/ApoE−/− HFD 16W, n=8). E. Bone marrow cells in mice under normal chow (n=3–6 per group). F. Bone marrow cells in mice under HFD for 4 weeks. (n=3–6 per group).
