2019

Hydrogels are 3D hydrophilic networks that can hold significant amounts of water within their structure, without dissolving in water. They can offer a combination of favorable properties, including high absorbency of biological fluids, biocompatibility, biodegradability, stimuli-responsiveness, high storage capacity and release ability of small and large therapeutic molecules. The hydrogel films designed for wound dressing may accomplish several functions, playing an important role in the healing processes. They can absorb and retain the wound exudates, stimulating fibroblast proliferation and keratinocyte migration and promoting re-epithelialization. Furthermore, they can incorporate and r…

Molecular mechanisms underlying proteins-membrane interaction

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 …
