WebbAlzheimer's disease is thought to be caused by the abnormal build-up of proteins in and around brain cells. One of the proteins involved is called amyloid, deposits of which form plaques around brain cells. The other protein is called tau, deposits of which form tangles within brain cells. WebbThese gene products are often proteins that function in metabolic pathways. The underlying basis for this altered behavior is a series of cellular changes, including misfolding of proteins that function in cell signaling pathways. The incorrect folding of mutant proteins causes their incorrect work.
