Alpha-synuclein preformed fibrils:a tool to understand Parkinson's disease and develop disease modifying therapy degenerationAlphadrivingParkinson's disease(PD)is the second most common neurodegenerative disorder characterized by multiple motor and nonmotor symptoms,which include,among others,constipation,sleep...
induces the downregulation of BDNF expression, leading to the onset and progression of PD-Dep. To test this hypothesis, we used preformed α-Syn fibrils (PFF) and stereotactically injected them into the right striatum of Sprague-Dawley rats. This method accurately simulated the pathological characte...
fragments might trigger the conversion of endogenous FL-αSyn into fragmented forms containing only the epitope of the seed. A similar scenario has been observed with fibrils produced with C-terminally truncated αSyn that activated caspase 1, which in turn converted endogenous FL-αSyn into the ...
We studied the microglial uptake of alpha‐synuclein preformed fibrils (PFFs) and the effect of pro‐inflammatory stimulation by interferon gamma. We demonstrate that combined exposure disrupts the phagosome maturation pathway while inflammatory stimuli suppress chaperone mediated autophagy and mitochondrial ...
A-syn pathology can be observed in in vitro and in vivo models through the introduction of pathological α-syn seeds in the form of preformed fibrils (PFFs) from recombinant α-syn monomers [13], α-syn obtained from brain samples of patients [14] or rodents carrying α-syn mutations [15...
(4 μl) of human recombinant α-Synuclein preformed fibrils (PFF) of three different types: (a) wt-PFF, (b) P-PFF and (c) S129A-PFF were injected at a constant flow rate of 0.27 μl/min. Equal volume PBS was used for control animals. An interval of 5 min was ...

2.1.3.3. Fibrils To the best of our knowledge, the binding of preformed fibrils to vesicles with membranes in different membrane phase states has not been investigated yet. However, when fibrils were formed in the presence of net negatively charged SUVs or GUVs large scale vesicle deformations ...
To functionally interrogate the role of catB in the handling of α-syn fibrils, we generated iPSC-derived DA neurons [41,42] and treated them with pre-formed α-syn fibrils (PFFs) and the catB inhibitor CA074me [56] at a dose (1 μM), shown to significantly reduce catB activity ...
