In pairwise comparisons, IP-10 was higher in MCI compared to AD (p = 0.019) and SCD (p = 0.040), TARC was higher in MCI versus AD (p = 0.012), CRP was increased in MCI compared to AD (p < 0.001) and SCD (p = 0.012) and ICAM-1 and VCAM-1 were higher in MCI versus AD (p = 0.011 for ICAM-1 and p = 0.002 for VCAM-1). The gene discussed is CXCL10; the disease is Alzheimer disease.
