Abstract:
Transthyretin-related hereditary amyloidosis (ATTR) is a progressive and potentially lethal genetic disorder, transmitted as an autosomal dominant trait. Tissue injury is induced by amyloid fibrils consisting of mutated transthyretin. The symptomatology and clinical course of ATTR is highly variable but typically causes peripheral polyneuropathy and autonomic dysfunction, leading to death within 10 years. As transthyretin is produced mainly in the liver, liver transplantation was the first successful therapeutic approach. Several disease-modifying treatments, including transthyretin stabilizers and gene therapy, are now available or in clinical development, with promising results.

Enzyme-linked Receptors
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...
Translation
Translation is the process of synthesizing proteins from the genetic information carried by messenger RNA (mRNA). Following transcription, it constitutes the final step in the expression of genes. This process is carried out by ribosomes, complexes of protein and specialized RNA molecules. Ribosomes, transfer RNA (tRNA), and other proteins produce a chain of amino acids—the polypeptide—as the end product of translation.
