Activated microglia overexpressing interleukin-1 (IL-1) are prominent neuropathological features of Alzheimer's disease. We used computerized image analysis to determine the number of IL-1 alpha-immunoreactive (IL-1 alpha +) microglia in cytoarchitectonic layers of parahippocampal gyrus (Brodmann's area 28) of Alzheimer and control patients. For cortical layers I and II, the numbers of IL-1 alpha + microglia were similar in Alzheimer and control patients. For layers III-VI, the numbers of IL-1 alpha + microglia were higher than that seen in layers I-II for both Alzheimer and control patients. Moreover, for layers III-VI, the number of IL-1 alpha + microglia in Alzheimer patients was significantly greater than that in control patients (relative Alzheimer values of threefold for layer III-V and twofold for layer VI; P < 0.05 in each case). The cortical laminar distribution of IL-1 alpha + microglia in Alzheimer patients correlated with the cortical laminar distribution of beta-amyloid precursor protein-immunoreactive (beta-APP+) neuritic plaques found in Alzheimer patients (r = 0.99, P < 0.005). Moreover, the cortical laminar distribution of IL-1 alpha + microglia in control patients also correlated with the cortical laminar distribution of beta-APP+ neuritic plaques found in Alzheimer patients (r = 0.91, P < 0.05). These correlations suggest that pre-existing laminar distribution patterns of IL-1 alpha + microglia (i.e. that seen in control patients) are important in determining the observed laminar distribution of beta-APP+ neuritic plaques in Alzheimer patients. These findings provide further support for our hypothesis that IL-1 is a key driving force in neuritic plaque formation in Alzheimer's disease.
