Circular dichroism study of lipid-lipid and lipid-protein interaction.

In vitro study of drug-protein interaction using electronic absorption, fluorescence, and circular dichroism spectroscopy

In the near future, design of a new generation of drugs targeting proteins will be required. Considering the complex bond between the drug and protein, the structure and stability of the target protein should be considered. So far, a series of in vitro investigations have been conducted with the aim of predicting drug-biological medium interactions. In these studies, use of spectroscopic method...

Cholesteryl ester transfer protein gene variations and macronutrient intakes interaction in relation to metabolic syndrome: Tehran lipid and glucose study

Objective(s): There are controversial results regarding the effect of the interaction of CETP polymorphisms with dietary fats on the lipid profiles. The aim of this study was to examine the effect of CETP polymorphisms (rs5882 and rs3764261) and macronutrient intakes interaction in relation to metabolic syndrome (MetS) or its components.Materials and Methods: In this nested case-control study, ...

A lipid transfer protein that transfers lipid

Very few lipid transfer proteins (LTPs) have been caught in the act of transferring lipids in vivo from a donor membrane to an acceptor membrane. Now, two studies (Halter, D., S. Neumann, S.M. van Dijk, J. Wolthoorn, A.M. de Maziere, O.V. Vieira, P. Mattjus, J. Klumperman, G. van Meer, and H. Sprong. 2007. J. Cell Biol. 179:101-115; D'Angelo, G., E. Polishchuk, G.D. Tullio, M. Santoro, A.D. Cam...

Molecular Theory of Chain Packing, Elasticity and Lipid-Protein Interaction in Lipid Bilayers

Interaction of cationic phosphorus dendrimers with lipid membranes

Large unilamellar liposomes and multilamellar vesicles consisting of DMPC interacted with cationic phosphorus-containing dendrimers CPDs G3 and G4. DSC and ζ -potential measurements have shown that liposomal-dendrimeric molecular recognition occurs due to the interaction between the complementary surface groups. Calorimetric studies indicate that the enthalpy of the transition of the lipids tha...
