Abstract
Amyloid β-protein (Aβ) deposits in the white matter were investigated by the double immunohistochemical staining for Aβ and neuritic, glial or vascular components. Reactive astroglia and neurite abnormality were absent around Aβ deposits in the white matter (w-Aβ) even those with a core. The association of w-Aβ with blood vessels was not consistent. Aggregates of activated microglia were found to be the sole but a consistent accompaniment of Aβ deposits even in the absence of other components such as neuron, synapse, neurite abnormality and reactive astroglia, as observed in the white matter. This suggests that the aggregates of activated microglia most likely represent one of the factors promoting the process of Aβ deposition.
