Background:
- Amyloid fibrils, typically associated with diseases like Alzheimer's, can also perform beneficial physiological functions in nature.
- Functional amyloids are found in diverse biological contexts, serving protective roles and influencing material properties.
Purpose of the Study:
- To review evidence of natural protective amyloids, focusing on silkmoth chorion protein analogues.
- To explore the potential of functional amyloids as inspiration for novel biomaterials.
Main Methods:
- Review of existing scientific literature on functional amyloids.
- Analysis of silkmoth chorion protein synthetic peptide-analogues.
- Discussion of other natural protective amyloids (e.g., fish chorion, Pmel17, hydrophobins, antifreeze protein).
Main Results:
- Silkmoth chorion protein analogues demonstrate the protective function of silkmoth chorion as a natural amyloid.

Amyloid Fibrils
Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining, normally used to...

Proteoglycans
Glycans, a class of complex heterogeneous molecules, can be covalently attached to proteins to form glycosylated proteins that regulate various physiological and pathological processes. Glycosylated proteins or glycoproteins comprise N-linked and O-linked oligosaccharides. O-glycosylation is the most common type of protein glycosylation. Here, glycans attach to the oxygen atom of the hydroxyl groups of Serine or Threonine residues. O-linked glycosylation occurs later in protein processing,...
Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
Protein Folding
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.
