ICAM-1 expression on F4/80+ CD45lo macrophages was significantly higher in ECM compared to hyperparasitemia (ANOVA: F(2) = 5.57; P<0.05), but no difference in expression level was found between PbA/FTY720 with either ECM or hyperparasitemia infections (Tukey's test: T = −2.35.24, P = 0.122 and T = −0.79, P = 0.720, respectively). The gene discussed is ICAM1; the disease is infection.
