CD163 and schizophrenia: When CD163+ cell density was analysed quantitatively by inflammatory subgroups, macrophage density was increased in high inflammation schizophrenia compared to low inflammation controls [Fig. 4G, 64%, ANCOVA (PMI), F(4,78) = 3.71, p = 0.008, post hoc p = 0.03] but did not differ significantly from low inflammation schizophrenia (p = 0.99), which showed an intermediate macrophage density compared to controls.
