Hereditary amyloidosis is, in general, a systemic condition related to multiple organ system involvement by beta-structured protein deposits. As such, it often mimics the more common forms of systemic amyloidosis: immunoglobulin light chain (AL, primary) and reactive (AA, secondary). The challenge diagnostically is to recognize hereditary amyloidosis as a distinct entity and then to determine t...
The amyloidoses are a group of disorders in which soluble proteins aggregate and deposit extracellularly in tissues as insoluble fibrils, causing progressive organ dysfunction. The kidney is one of the most frequent sites of amyloid deposition in AL, AA, and several of the hereditary amyloidoses. Amyloid fibril formation begins with the misfolding of an amyloidogenic precursor protein. The misf...
In contrast to AL amyloidosis, where clonal plasma cells in bone marrow produce immunoglobulins that are amyloidogenic, and familial amyloidoses in which a mutant protein forms amyloid fibrils, the incidence of AA amyloidoses has been reduced since the treatment of infectious diseases and rheumatoid arthritis improved. AA amyloidoses are due to amyloid formed from serum amyloid A, an acute phas...
The amyloidoses are a group of hereditary or acquired disorders caused by the extracellular deposition of insoluble protein fibrils that impair tissue structure and function. All amyloidoses result from protein misfolding, a common mechanism for disorders in older persons, including Alzheimer's disease and Parkinson's disease. Abnormalities in the protein transthyretin (TTR), a serum transporte...
Amyloidoses are diseases characterized by abnormal protein folding and self-assembly, for which no cure is available. Inhibition or modulation of abnormal protein self-assembly, therefore, is an attractive strategy for prevention and treatment of amyloidoses. We examined Lys-specific molecular tweezers and discovered a lead compound termed CLR01, which is capable of inhibiting the aggregation a...
