Serum cholesterol levels are elevated in ApoE^−/− mice and remain unchanged during semi-chronic arthritis. Serum levels of a TC, b LDL/vLDL, and c HDL in non-arthritic and arthritic C57BL/6 (control, n = 2 non-arthritic and n = 15 arthritic) and ApoE^−/− (n = 3 non-arthritic and n = 6 arthritic) mice at 4–6 months. Data are represented as mean ± SEM. Asterisk denotes statistically significant differences: ***p < 0.001
