Figure 3

Drd2 deficiency aggravates CIA clinical symptoms and proinflammatory cytokine upregulation. This experimental design was similar to that of Figure 2, except that Drd2-deficient mice (no quinpirole treatment) and Drd1-deficient mice were used instead. Con: control; WT: wild-type mice; NS: no significance; versus WT or WT Con; , versus WT CIA.
