Microglia express ABI3 in the brains of Alzheimer's disease and Nasu-Hakola disease.

ABSTRACT: Nasu-Hakola disease (NHD) is a rare autosomal recessive leukoencephalopathy caused by a loss-of-function mutation of either TYROBP (DAP12) or TREM2 expressed in microglia. A rare variant of the TREM2 gene encoding p.Arg47His causes a 3-fold increase in the risk for late-onset Alzheimer's disease (LOAD). A recent study demonstrated that a rare coding variant p.Ser209Phe in the ABI family member 3 (ABI3) gene, a regulator of actin cytoskeleton organization, confers risk of developing of LOAD, although the pattern of ABI3 expression in AD and NHD brains with relevance to microglial pathology remains to be characterized. We investigated the cell type-specific expression of ABI3 in the brains derived from four non-neurological controls (NC), ten AD and five NHD cases by immunohistochemistry. We
