Interaction of cationic phosphorus dendrimers with lipid membranes
Authors
Abstract:
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 that interact with CPDs is dependent on the dendrimers generation. These results can be used in order to rationally design mixed modulatory liposomal locked-in dendrimeric, drug delivery nano systems.

full textInteraction of cationic peptides with bacterial membranes.
A common feature of cationic peptides is that their site of action is at the membrane due to channel formation, and that they tend to possess strong selectivity towards their target membrane. For example, although moth cecropin and bee melittin are members of the same family of peptides that adopt amphipathic a-helical structures, the cecropins are strongly antibacterial and demonstrate minimal...
full textInteraction of Polyamidoamine (pamam) Dendrimers with Glassy Carbon Supported Bilayer Lipid Membranes
Electrochemical techniques were used to monitor the formation of a 1,2-dioleoyl-sn-glycero-3-phosphocholine supported bilayer lipid membrane (sBLM) on a glassy carbon electrode and to investigate interactions of polyamidoamine (PAMAM) dendrimers with the sBLM. Dendrimers of generation 2 through generation 4 (G2-G4) did not cause significant damage to the sBLM, whereas G5G7 dendrimers created la...
full textDNA interaction with freestanding cationic lipid bilayers
We study the interaction of ds-DNA molecules with freestanding and supported cationic lipid bilayers. DNA fragments of different lengths (5, 10, 20, and 48 kbp) were adsorbed on lipid membranes consiting mainly of zwitterionic DOPC with added fractions of cationic DOTAP (1...10 %). Freestanding bilayers were modeled using giant unilamellar vesicles of sizes >100 μm. Supported lipid bilayers wer...
full textInteraction of cationic lipid/DNA complexes with model membranes as determined by neutron reflectivity.
Transfection of cells by DNA for the purposes of gene therapy can be effectively engineered through the use of cationic lipid/DNA "lipoplexes", although the transfection efficiency of these complexes is sensitive to the neutral "helper" lipid included. Here, neutron reflectivity has been used to investigate the role of the helper lipid present during the interaction of these lipoplexes with mod...
