The terms on the second line describe monomer dissociation, i.e. the inverse process of elongation. is the rate constant of monomer dissociation. The terms on the third line describe the effect of fragmentation, which is assumed to occur homogeneously along fibrils with rate constant . Finally, the terms on the last line describe primary and ...
Redlich used the term 'miliary sclerosis' to describe plaques because he thought they resembled millet seeds, and he was the first to refer to the lesions as 'plaques'. [ 4 ] In the early 20th century, Oskar Fischer noted their similarity to actinomyces 'Drusen' (geode-like lesions), leading him to call the degenerative process 'drusige Nekrose ...
Amyloid-beta precursor protein (APP) is an integral membrane protein expressed in many tissues and concentrated in the synapses of neurons. It functions as a cell surface receptor [ 5 ] and has been implicated as a regulator of synapse formation , [ 6 ] neural plasticity , [ 7 ] antimicrobial activity, [ 8 ] and iron export . [ 9 ]
The term "amyloid" is derived from the Latin amyloideus ("starch-like"). [1] It refers to the fact that starch gives a similar reaction, also called an amyloid reaction. The test can be on microscopic features, such as spore walls or hyphal walls, or the apical apparatus or entire ascus wall of an ascus , or be a macroscopic reaction on tissue ...
Misfolded proteins can form protein aggregates or amyloid fibrils, get degraded, or refold back to its native structure. In molecular biology, protein aggregation is a phenomenon in which intrinsically-disordered or mis-folded proteins aggregate (i.e., accumulate and clump together) either intra- or extracellularly.
Acute-phase serum amyloid A proteins (A-SAAs) are secreted during the acute phase of inflammation.These proteins have several roles, including the transport of cholesterol to the liver for secretion into the bile, the recruitment of immune cells to inflammatory sites, and the induction of enzymes that degrade extracellular matrix.
An amyloid is any of certain insoluble fibrous protein aggregates. Amyloid may also refer to: Amyloid (mycology), a chemical reaction used in characterization of fungi; Amyloid, the Amyloid: the Journal of Protein Folding Disorders peer-reviewed scientific journal
