Sentences with phrase «fibrils aggregating»

Instead, the plaques use the exact same structure that is the hallmark of Alzheimer's — steel - strength fibrils aggregating into plaques — to entomb the offenders.

Not exact matches

Co-lead researcher, Australian National University Professor John Carver, said that two unrelated proteins aggregate in UHT milk over a period of months to form clusters called amyloid fibrils, which cause the milk to transform from a liquid into a gel.

«Large aggregates of ALS - causing protein might actually help brain cells: UNC School of Medicine scientists add to evidence that small aggregates of SOD1 protein are the brain - cell killing culprits in ALS, but the formation of larger, more visible, and fibril - like aggregates of the same protein may protect brain cells.»

Left: cells with large, fibril - like aggregates of SOD1 protein.

While these compounds did not reduce the amount of protein aggregates, they were found to reduce the protein's toxicity and to increase the stability of amyloid fibrils — a finding that lends further evidence to the theory that smaller assemblies of amyloid - beta known as oligomers, and not the fibrils themselves, are the toxic agents responsible for Alzheimer's symptoms.

The cell culture experiments showed that MAbs prevented the uptake of misfolded α - syn fibrils by neurons and sharply reduced the recruitment of natural α - syn into new Lewy body aggregates.

«These findings suggest that the ability of proteins to aggregate into amyloid fibrils can be considered a more general property of proteins than previously believed,» says Massimo Stefani, a protein chemist at the University of Florence in Italy who co-led the project.

Tau and Mcc were induced to form amyloid aggregates by incubation in buffer, and amyloid fibril formation was characterized by ThT and transmission electron microscopy (Fig.

It has been demonstrated that silk properties (in terms of different reeling methods [32], [42], environmental conditions [8], [20], types of silk [e.g. dragline, viscid or egg sac silk][22], [24], [34]-RRB- are species - specific and lead to silk - based peptide fibrils or protein aggregates with different structural and mechanical properties.

We are interested in the role of secretory chaperones in the biochemistry and cell biology of the neuron and have shown that two small secretory chaperones can block the formation of both Abeta oligomers and fibrils in vitro and neurootoxic aggregates in cell culture models.

Four of the mAbs, 2T5C9, 2G9C, T1F11, and TB2H7, demonstrated diagnostic potential in enzyme - linked immunosorbent assays (ELISA) by their low to sub-nanomolar cross-reactivity with recombinant wild - type (WT) and mutant TTR aggregates and lack of binding to native TTR or amyloid fibrils formed by other peptides or proteins.

To address this, we have generated 22 monoclonal antibodies (mAbs) against aggregates formed by a blood transport protein, transthyretin (TTR), which primarily forms amyloid fibrils in a patient's heart and / or peripheral nerves.

They found that abnormal clumps of α - Syn formed by small fibrils act as «seeds» that induce normal α - Syn molecules to misfold and form aggregates.
