Amyloid Beta Is a Ligand for FPR Class Receptors

Description of Technology: Alzheimer's disease is the most important dementing illness in the United States because of its high prevalence. Five to ten percent of the United States population 65 years and older are afflicted with the disease. In 1990 there were approximately 4 million individuals with Alzheimer's, and this number is expected to reach 14 million by the year 2050. It is the fourth leading cause of death for adults, resulting in more than 100,000 deaths annually. Amyloid beta has been identified as playing an important role in the neurodegeneration of Alzheimer's disease. However, the mechanism by which this occurred was unknown, but has been postulated to be either direct or indirect through an induction of inflammatory responses.

The NIH announces the identification of the 7-transmembrane, G-protein-coupled receptor, FPRL-1, in the cellular uptake and fibrillar aggregation of amyloid ββ(Aββ) peptides. The Aββ peptides use the FPRL-1 receptor to attract and activate human monocytes and mouse microglial cells (publications referenced below), and have been identified as a principal component of the amyloid plaques associated with Alzheimer's disease. In addition, the known anti-inflammatory drug, Colchicine, has been shown to inhibit the FPRL1 activation by amyloid ββ** and the internalization of FPRL1/amyloid beta complexes.
