Amyloid fibril proteins

Mechanisms of Ageing and Development, 2002
Amyloidosis refers to a group of protein folding diseases. Various innocuous and soluble proteins in physiological conditions polymerize to insoluble amyloid fibrils in several serious diseases, including Alzheimer's disease (AD) and prion diseases. In addition, senile amyloidosis is a form of amyloidosis in which the incidence and severity of amyloid ...

Protein Fibrils Induce Emulsion Stabilization

Langmuir, 2016
The behavior of an oil-in-water emulsion was studied in the presence of protein fibrils for a wide range of fibril concentrations by using rheology, diffusing wave spectroscopy, and confocal laser scanning microscopy. Results showed that above a minimum fibril concentration depletion flocculation occurred, leading to oil droplet aggregation and ...

Zona Pellucida Proteins, Fibrils, and Matrix

Annual Review of Biochemistry, 2020
The zona pellucida (ZP) is an extracellular matrix that surrounds all mammalian oocytes, eggs, and early embryos and plays vital roles during oogenesis, fertilization, and preimplantation development. The ZP is composed of three or four glycosylated proteins, ZP1–4, that are synthesized, processed, secreted, and assembled into long, cross-linked ...

Protein Microgels from Amyloid Fibril Networks

ACS Nano, 2015
Nanofibrillar forms of proteins were initially recognized in the context of pathology, but more recently have been discovered in a range of functional roles in nature, including as active catalytic scaffolds and bacterial coatings. Here we show that protein nanofibrils can be used to form the basis of monodisperse microgels and gel shells composed of ...

Plasma Protein Constituents of Amyloid Fibrils

The Journal of Immunology, 1967
Summary Rabbits immunized with crude whole fibrils from three amyloidotic spleens formed antibodies to the following plasma proteins: γ-A-immunoglobulin, γ-G-immunoglobulin, fibrinogen, a protein with β-globulin mobility and a protein with α-1-globulin mobility (P-component).

The Purification of Amyloid Fibril Proteins

Preparative Biochemistry, 1972
Abstract Amyloid fibril concentrates have been fractionated and shown to have homogeneous fragments of the variable region of immunoglobulin proteins as their major protein constituent. Amyloid fibril protein purification was performed on ten amyloid preparations by sequential gel filtration on Sepharose 4 B and Sephadex G-100 columns equilibrated with

Protein aggregation: more than just fibrils

Biochemical Society Transactions, 2009
The aggregation of misfolded proteins into amyloid fibrils, and the importance of this step for various diseases, is well known. However, it is becoming apparent that the fibril is not the only structure that aggregating proteins of widely different types may adopt.

Inhibiting ice recrystallization by amyloid protein fibrils

International Journal of Biological Macromolecules, 2023
Ice recrystallization is harmful to the quality of frozen foods and the cryopreservation of cells and biological tissues, requiring biocompatible materials with ice recrystallization inhibition (IRI) activity. Emerging studies have associated IRI activity with amphiphilic structures.

Dendrimer Effects on Peptide and Protein Fibrillation

Macromolecular Bioscience, 2007
AbstractDendrimers are synthetic, symmetrically branched polymers that can be manufactured to a high degree of definition and therefore present themselves as monodisperse entities. Flexible and globular in shape and compartementalized into a partly inaccessible interior and a highly exposed surface, they offer numerous possibilities for interactions ...
