Macrophages and granulocytes were evaluated by morphology. CD3 expression. CD22 expression. Macrophage expression. Granulocyte expression. No significant differences between treated animals and controls were observed for CD3 and CD22 expression (= 0.4 for both). Statistically significant differences were observed for macrophage and granulocyte expression between IFN-β-treated mice and saline-treated mice (= 0.04 and 0.009, respectively). *Statistically significant difference.
