The total density of each type (reactive/primed/amoeboid) of IBA1 protein IR microglia also did not differ between depressed suicides and controls in the dorsal anterior cingulate cortex (dACC) region [56], dorsal or ventral prefrontal white matter (including SCZ and AD) [57], or the expression of microglial QUIN in the left hippocampal CA1 and right CA2/3 [53]. The gene discussed is AIF1; the disease is Alzheimer disease.
