Figure: (Left): Amyloid peptide. i-iii : Typical electron micrographs of amyloid fibrils showing their linear, unbranched and flexible nature (i) and repeating twists of fibrils at regular intervals (ii & iii). (Far Right): A GPCR known as PAR2 (green) and one of its activating proteases, trypsin (red), coexpressed in neurons of the cerebral cortex of the rat (immuohistochemical photomicrograph).
