We found that mRNA levels of macrophage chemoattractant, CCL2, were elevated in schizophrenia compared to controls [main effect of diagnosis: F(1,130) = 16.71, p = 7.58E-05], and were increased in high inflammation individuals compared to low inflammation individuals [main effect of inflammation: F(1,130) = 32.08, p = 9.05E-08]. Here, CCL2 is linked to schizophrenia.
