English: "A schematic representation showing the roles of mononuclear phagocytes in Alzheimer’s disease. A penetrating cerebral artery is shown on the left, and a β-amyloid plaque within the brain parenchyma is shown to the right. Peripheral mononuclear phagocytes (macrophages) are infiltrating the brain parenchyma and homing to the β-amyloid plaque, where they phagocytose and clear deposited Aβ. Peripheral mononuclear phagocytes are depicted in green, brain-resident microglia are magenta, neurons are blue, and the β-amyloid plaque is shown in red".~Macrophages in Alzheimer’s disease: the blood-borne identity[1]
