Molecular interactions of Parkinson's α-synuclein with membranes.
Νeutron reflectometry is employed to investigate the interaction of α-synuclein with lipid membranes. In these studies, we discovered the interaction between α-synuclein and glucocerebrosidase, the enzyme deficient in Gaucher disease, to explain why mutations in GBA, the gene encoding glucocerebrosidase, is a risk factor for Parkinsonism.

Neutrotransmitter interaction with lipid membranes.
The activity of many membrane proteins is remarkably sensitive to slight changes in the composition of the lipid bilayer in which they are embedded. An example is the (unspecific) interaction of neurotransmitters with the post-synaptic membrane which we aim to quantify in model studies.

Enzybiotics as antimicrobial agents.
PlyC, a bacteriophage-encoded endolysin is a potent agent for controlling intracellular Streptococci (Spy) that often result in refractory infections. We established that PlyCB interacts strongly with phosphatidylserine (PS) whereas its interaction with other lipids is weak, suggesting specificity for PS as its cellular receptor.
