Direct observation of alpha-lactalbumin, adsorption and incorporation into lipid membrane and formation of lipid/protein hybrid structures

2019

The interaction between proteins and membranes is of great interest in biomedical and biotechnological research for its implication in many functional and dysfunctional processes. We present an experimental study on the interaction between model membranes and alpha-lactalbumin (alpha-La). alpha-La is widely studied for both its biological function and its anti-tumoral properties. We use advanced fluorescence microscopy and spectroscopy techniques to characterize alpha-La-membrane mechanisms of interaction and alpha-La-induced modifications of membranes when insertion of partially disordered regions of protein chains in the lipid bilayer is favored. Moreover, using fluorescence lifetime imag…

Phasor-FLIM for a direct investigation of Transportan 10 interactions with model membranes

2023

Transportan 10 (TP10), a short and positive charged peptide, belonging to the family of the cell penetrating peptides has gained increasing attention for its antimicrobial and anticancer activity but also for its applications in drug delivery as it is able to translocate therapeutic molecules in cellular environment. Due to the complexity of the phenomena involved in cellular uptake and following processes, which strongly depend on the membrane lipid composition, structural details of the peptide (e.g., charge, hydrophobicity, steric hindrance) and environmental conditions, it is not easy to understand the general rules governing them. Here, we combine spectroscopic techniques and fluoresce…
