A. Ankle circumference was determined in wild type (WT) mice that were fed on RD or 60% HFD for 10 weeks following i.a. injection with 10 μg of LPS and mice were sacrificed after 72h of LPS injection, n=10. B. RD and HFD ankles harvested after 72h of LPS injection were H&E stained (orig. mag. x 200), and C. inflammation, lining thickness and bone erosion were quantified on a 0-5 scale, n=10. D. % lean mass and fat mass were assessed by DXA in TLR4 mediated arthritis mice (72h) fed on RD and HFD, n=10. E. Protein levels of proinflammatory cytokines (TNF-α, IL-1β, IL-6 and MIP2) and F. chemokines (CXCL1, CXCL5, CCL2, CCL3, CCL20 and CCL5) were quantified by ELISA in TLR4 arthritic mice (72h) fed on RD and HFD, n=5. Values are mean ± SE. * indicates p<0.05.
