  Therefore, a better understanding of the peptide/lipid (P/L) interaction is essential to help decipher their mechanism of action. Among the different biophysical methods that can be used to fully characterize P/L interactions, differential scanning calorimetry (DSC) allows determining the peptide effect on the lipid phase transitions, a. While the primary focus of the book is on the systems important in colloid and interface science, a more general goal is to introduce the reader to several theoretical methods that are useful in applications of statistical mechanics to materials.

Our goal was to develop a mechanistic explanation of how CBDs modulate peptide–lipid interactions leading to their observed bioactivities, in order to better understand their potential for clinical applications.

Peptides are involved in numerous biological processes that include: killing bacteria, signal transduction, cell growth, and synaptic transmission. This book presents an overview of the interaction of peptides with synthetic and biological membranes, and includes state-of-the-art methodology, computer simulations and theoretical analysis.

Simon Pages Peptide-Lipid Interaction: Shedding Light into the Mode of Action and Cell Specificity of Antimicrobial Peptides. The interactions between peptides and lipids are of fundamental importance in the functioning of numerous membrane-mediated cellular processes including antimicrobial peptide action, hormone-receptor interactions, drug bioavailability across the blood-brain barrier and viral fusion processes.

Moreover, a major goal of modern biotechnology is obtaining new potent pharmaceutical agents whose biological action is dependent on the binding of peptides to lipid-bilayers.

Previous studies suggested that Aβ peptide can interact with phospholipid membranes directly. There are two types of Aβ-membrane interactions (Fig.

One type is that Aβ peptide inserts into the membrane and forms a pore-like structure. The insertion may induce the leakage of the membrane and thus trigger the cell death. This volume contains a comprehensive overview of peptide-lipid interactions by leading researchers.

The first part covers theoretical concepts, experimental considerations, and thermodynamics. The second part presents new results obtained through site-directed EPR, electron microscopy, NMR, isothermal calorimetry, and fluorescence quenching.

The importance of peptide-lipid interactions was examined using surface plasmon resonance and fluorescence spectroscopy methodologies.

Our studies showed that tachyplesin peptides and their cyclic analogues were most potent against Gram-negative bacteria and melanoma cell lines, and showed a preference for binding to negatively-charged lipid.

The results with these model systems demonstrate changes in peptide−lipid interactions that may be related to the observed biological properties of this peptide. This work was supported by Grant MT from the Canadian Institutes of Health Research and Grants HL and RO1 HL from the U.S.

Quartz crystal microbalance (QCM), surface plasmon resonance (SPR) spectroscopy and electrochemical impedance spectroscopy (EIS) are useful techniques to investigate in details of the peptide-membrane interaction.Motivated by that fact, the scope of this thesis is to study these antimicrobial peptide-lipid membrane interactions.

In particular, we attempt to study these interactions with a quantitative approach. For that purpose, we consider the three archetypal α-helical antimicrobial peptides mastoparan X, melittin, and magainin 2 as model peptides.
