Protein/lipid coaggregates are formed during α-synuclein-induced disruption of lipid bilayers.
2014
Amyloid formation is associated with neurodegenerative diseases such as Parkinson's disease (PD). Significant α-synuclein (αSN) deposition in lipid-rich Lewy bodies is a hallmark of PD. Nonetheless, an unraveling of the connection between neurodegeneration and amyloid fibrils, including the molecular mechanisms behind potential amyloid-mediated toxic effects, is still missing. Interaction between amyloid aggregates and the lipid cell membrane is expected to play a key role in the disease progress. Here, we present experimental data based on hybrid analysis of two-photon-microscopy, solution small-angle X-ray scattering and circular dichroism data. Data show in real time changes in liposome …
Protein-membrane interaction: insights from advanced microscopy
2017
The interaction between proteins and membranes is sub ject of renewed interest in biomedical and biotechnologi cal research for its implication in many functional and dys functional processes and for its pharmaceutical applications. It has been shown that the interaction between amyloido genic proteins and membranes results in mutually destruc tive structural perturbations. The study we present is focused on the interaction between synthetic model membranes and alpha-lactalbumin (α-La), widely studied for its biolog ical function since it can induce apoptosis in tumor cells. Upon α-La addition to giant vesicles (GVs) samples, the sys tem has been characterized by means of spectroscopy meth …
