To date, 37 human proteins have been found to form amyloid in pathology and be associated with well-defined diseases. [2] The International Society of Amyloidosis classifies amyloid fibrils and their associated diseases based upon associated proteins (for example ATTR is the group of diseases and associated fibrils formed by TTR). [3]
Amyloid, the aggregation, or clumping, of proteins, is resistant to degradation by the body. Amyloids are mostly fibrils, while also containing a P component, apolipoprotein, collagen, fibronectin, and laminin. [2] The P component, a pentameric protein, stabilizes the fibrils of the amyloid, which reduces their clearance from the body. [1]
Amyloid light chains deposition in shoulder joint causes enlarged shoulders, also known as "shoulder pad sign". [18] Amyloid light chain depositions can also cause bilateral symmetric polyarthritis. [18] The deposition of amyloid proteins in the bone marrow without causing plasma cell dyscrasias is called amyloidoma. It is commonly found in ...
The transthyretin protein is a tetramer. The tetramer has to dissociate into misfolded monomers to aggregate into a variety of structures including amyloid fibrils. Because most patients are heterozygotes, they deposit both mutant and wild type TTR subnits. [citation needed] FAP is inherited in an autosomal dominant manner. [2]

As of the 2023 Census estimates, the population of Indiana was 6,862,199, the average population of Indiana's 92 counties is 74,589, with Marion County as the most populous (968,460), and Ohio County (6,004) the least. 54 counties have 30,000 or more people; 17 counties have populations exceeding 100,000, five of which exceed 250,000; and only ...
Amyloid beta (Aβ) is a small protein, most often 40 or 42 amino acids in length, that is released from a longer parent protein called the Aβ-precursor protein (APP). [24] APP is produced by many types of cell in the body, but it is especially abundant in neurons. It is a single-pass transmembrane protein, passing once through cellular ...
These genes are also highly enriched in cell adhesion Gene Ontology (GO) terms and often map to chromosomal fragile sites. [123] The majority of known Alzheimer's disease risk gene products including the amyloid precursor protein (APP) and gamma-secretase, as well as the APOE receptors and GWAS risk loci take part in similar cell adhesion ...
