Transthyretin (TTR) is a beta-sheet rich protein whose plasma half life is 1.9 days. It behaves as a tetramer and binds to retinol binding protein (RBP) and thyroxin in plasma. Since TTR is a tryptophan-rich-protein, the protein is used as a useful marker protein for nutrition supporting team (NST). ⋯ We synthesized ATTR Y78P, a spontaneously misfolded TTR, and injected it to amyloid laden transgenic mice having human ATTR V30M to induce the antibody for amyloid fibrils. As we expected, amyloid deposition was significantly reduced by the injection of ATTR Y78P to the mice. These therapies may become novel strategies for essential FAP therapy instead of liver transplantation.
