IL10 and retinal disorder: Finally, and of further interest, while IL-10 levels were low in the retina of diabetic mice with retinopathy, the expression of this anti-inflammatory cytokine was significantly increased after the injection of either MC1 or MC5 agonist, for example, +64 ± 7% and +56 ± 4.2% for BMS-470539 and PG-901, respectively (p < 0.01 versus diabetic mice) (Figure 9).
