Direct observation of prion protein oligomer formation ...

aggregation process remain poorly de ned. Increasing evidence argues that other disease-associated proteins, such as Ab,tau,anda-synuclein, also share a similar aggregation mechanism with PrP6–11 that is classi ed as a 'prion-like' mechanism. The early stage of bril formation has been associated with

May 27, 2014 · This auto-catalytic mechanism dominates the aggregation process of Aβ42 under quiescent solution conditions . These results show that the overall kinetics of aggregation of Aβ42 are determined by a complex combination of primary and secondary processes, as well as by the growth of oligomeric nuclei and fibrils.

Protein aggregation processes: In search of the mechanism

Of particular relevance to the mechanism of the aggregation process is that these systems typically exhibit a very long lag period, in which nothing appears to be happening, followed by a rapid formation of the fibril. This review deals primarily with an exploration of what actually does happen during the early steps that delineate the lag ...

Protein aggregation processes: In search of the mechanism

polymerization implies a more defined process. This dis-tinction between polymerization and aggregation becomes unclear when dealing with the formation of amyloids because both specific and nonspecific processes may be occurring at the same time. I start with a discussion of polymerization mechanisms, in which the monomers are

This is a systematic investigation, using in situ synchrotron small-angle X-ray scattering, of the mechanisms of aggregation of sulfate zirconia sols under different preparation conditions. We have studied the effects of the variations of acid, water, and sulfate contents on the process of aggregate growth. These effects were investigated using open and sealed sample cells.
