Role of LRP in TGFbeta2-mediated neuronal uptake of Abeta and effects on memory.

There is increasing evidence that soluble amyloid-beta peptide (Abeta) uptake into neurons is an early event in the pathogenesis of Alzheimer's disease (AD). Identification of the early events leading to neuronal dysfunction is key to developing therapeutic strategies, but relative roles of receptors and factors modulating uptake are poorly understood. Studies have shown that transforming growth factor beta (TGFbeta), particularly TGFbeta2, can influence the targeting of Abeta to cells in vitro.
