Fibril fragmentation in amyloid assembly and cytotoxicity: When size matters [PDF]

, 2010
Amyloid assemblies are associated with several debilitating human disorders. Understanding the intra- and extracellular assembly of normally soluble proteins and peptides into amyloid aggregates and how they disrupt normal cellular functions is therefore

Amyloid tracers detect multple binding sites in Alzheimer´s disease brain tissue. [PDF]

, 2013
Imaging fibrillar amyloid-β deposition in the human brain in vivo by positron emission tomography has improved our understanding of the time course of amyloid-β pathology in Alzheimer’s disease. The most widely used amyloid-β imaging tracer so far is 11C-

Destruxin E Decreases Beta-Amyloid Generation by Reducing Colocalization of Beta-Amyloid-Cleaving Enzyme 1 and Beta-Amyloid Protein Precursor [PDF]

, 2009
Alzheimer-disease-associated beta-amyloid (A beta) is produced by sequential endoproteolysis of beta-amyloid protein precursor (beta APP): the extracellular portion is shed by cleavage in the juxtamembrane region by beta-amyloid-cleaving enzyme (BACE ...

An Imaging and Systems Modeling Approach to Fibril Breakage Enables Prediction of Amyloid Behavior [PDF]

, 2013
Delineating the nanoscale properties and the dynamic assembly and disassembly behaviors of amyloid fibrils is key for technological applications that use the material properties of amyloid fibrils, as well as for developing treatments of amyloid ...

Prevalence and determinants of iron deficiency in cardiac amyloidosis

ESC Heart Failure, 2022
Aims Iron deficiency (ID) is common in patient with chronic heart failure (HF) and has been widely studied. In contrast, data concerning ID in cardiac amyloidosis (CA) are limited.

Analysis of Toxic Amyloid Fibril Interactions at Natively Derived Membranes by Ellipsometry [PDF]

, 2015
There is an ongoing debate regarding the culprits of cytotoxicity associated with amyloid disorders. Although small pre-fibrillar amyloid oligomers have been implicated as the primary toxic species, the fibrillar amyloid material itself can also induce ...

A multidisciplinary case report of multiple myeloma with renal and cardiac involvement: a look beyond amyloidosis

BMC Nephrology, 2022
Background Multiple myeloma (MM) is a malignant neoplasm associated with kidney involvement in nearly half of the patients. Cast nephropathy, monoclonal immunoglobulin deposition disease (MIDD), and light chain (AL) amyloidosis are the most common ...

Fibril Fragmentation Enhances Amyloid Cytotoxicity [PDF]

, 2009
Fibrils associated with amyloid disease are molecular assemblies of key biological importance, yet how cells respond to the presence of amyloid remains unclear. Cellular responses may not only depend on the chemical composition or molecular properties of

Amyloidosis of the gastrointestinal tract: a 13-year, single-center, referral experience

Haematologica, 2013
Amyloidosis of the gastrointestinal tract, with biopsy-proven disease, is rare. We reviewed a series of patients who presented with biopsy-proven gastrointestinal amyloidosis and report their clinical characteristics, treatments, and survival.
