A key result is the necessity of the alkyl chains of the alkylammonium ion templates to stabilize cavities in intermediate silicate oligomers as well as their role to assist the aggregation of such silicate clusters to form channel intersections.
The substrate temperature thus adopted seems to assist in the aggregation of PbSe nanocrystals.
It seems to confirm that increased HSP70 expression would assist in blocking aggregation and refolding of damaged proteins as a general protective response.
The reduction of proteotoxic stress emanating from oxidatively modified proteins has been attributed to the chaperone function of HSPs, which tend to prevent protein denaturation and aggregation, assist in the correct refolding of affected proteins, promote GSH reduction, and maintain proteasome function (reviewed in [ 428, 429, 434]).
Heat shock proteins (HSPs) with a molecular weight of approximately 70 kDa are located in most cellular compartments, in which they support the folding of nascent polypeptides, prevent protein aggregation and assist the transport of other proteins across membranes [1], [2].
They also serve as a cochaperone of HSP70 and assist inhibition of protein aggregation [ 34].
Under stress, they prevent protein aggregation and assist with refolding; under normal conditions, they play a housekeeping role.
To minimize protein aggregation, chaperones assist protein folding; when this is not effective, chaperones assist in targeting damaged substrates for clearance by the ubiquitin proteasome system (UPS) and the lysosome-based degradation systems.
Such measurements could assist in minimizing protein aggregation and in maintaining the consistency in the size distribution and morphology of residual particle populations during formulation development, clinical trials, manufacturing, and storage.
HSP70s function in preventing aggregation, assisting refolding, protein import and translocation, signal transduction, and transcriptional activation [ 42, 46].
