Figure 1. Effects of CC-chemokine receptor 2 (CCR2) siRNA on CCR2 expression in transfected cells. Primary cultured retinal microglia were treated with specific siRNA to knock down the expression of CCR2. Representative CCR2 knockdown was identified with western blot analysis with maximum downregulation of approximately 75%. Results are statistically significant (**p<0.01 Student t test).
