Abstract
Here, we show that amyloid-beta (Abeta) is capable to prime and activate the respiratory burst of human macrophages. Previously, the N-terminus of Abeta(1-42) has been shown to contain a cell binding domain that is implicated in eliciting neuropathogenic microglia in vitro. To evaluate the role of this domain in the Abeta(1-42)-induced respiratory burst activity, the effect of Abeta subfragments on the Abeta(1-42)-induced superoxide release were studied. On the basis of the antagonistic properties of Abeta(1-16), it is concluded that the N-terminal region of Abeta is critical for the cellular binding and consequent activation of the respiratory burst of human phagocytes
