Protein misfolding and deposition in the brain are implicated in the etiology of numerous neurodegenerative disorders. Here, organic solutes characteristic of microorganisms adapted to hot environments, were tested on experimental cell models of Huntington's and Parkinson's diseases. Diglycerol phosphate, di-myo-inositol phosphate, mannosylglycerate, and mannosylglyceramide were not toxic to the cells, at 10 mM concentration, but caused a decrease in cell density, which suggested an effect on proliferation. In contrast, mannosyl-lactate, an artificial analogue of mannosylglycerate, had a negative impact on cell viability. Concerning protein aggregation, inclusions of mutant huntingtin were reduced in the presence of diglycerol phosphate and di-myo-inositol phosphate, increased with mannosylglycerate, while mannosyl-lactate and mannosylglyceramide had no significant effect. α-Synuclein aggregation was not affected by the solutes tested, except for di-myo-inositol phosphate that led to a slight increased percentage of cells displaying visible aggregates. These solutes might be useful in the development of therapies for protein misfolding diseases. |
