Colocalisation of plasma derived apo B lipoproteins with cerebral proteoglycans in a transgenic-amyloid model of Alzheimer's disease

► Significant amyloid-beta is associated with apolipoprotein (apo) B lipoproteins. ► Some proteoglycans are associated with apo B lipoproteins in amyloid plaques. ► Proteoglycans may contribute to amyloidosis.
