From: Elevated levels of circulating IL-18BP and perturbed regulation of IL-18 in schizophrenia

Concentration of IL-18, IL-18BP and free IL-18 in serum of all HC (n = 77) and SCZ (n = 77) subjects (upper panels) and in two age subgroups of HC and SCZ subjects (lower panels), including subjects with age ≤ 30 years (HC: n = 15, mean age = 24.4 ± 0.7; SCZ: n = 18, mean age = 25.6 ± 0.7) and age ≥ 50 years (HC: n = 22, mean age = 56.5 ± 1; SCZ: n = 19, mean age = 56.1 ± 1.1). Asterisks inside the graphs indicate the significance of comparisons of SCZ vs. HC: * P < .001, ** P < .0001. HC, healthy controls; SCZ, schizophrenic patients.
