Autor: Claudio M. Fader Kaiser, Patricia S. Romano, M. Cristina Vanrell, Cristian A. Pocognoni, Julieta Jacob, Benjamín Caruso, Laura R. Delgui

Publikováno v: Frontiers in Cell and Developmental Biology, Vol 9 (2022)

Lipid droplets (LD) have long been considered as mere fat drops; however, LD have lately been revealed to be ubiquitous, dynamic and to be present in diverse organelles in which they have a wide range of key functions. Although incompletely understoo

We studied the surface properties of Aβ(1-40) amyloid peptides mixed with 1-palmitoyl-2-oleoyl-phosphatidylcholine (POPC) (liquid state) or 1,2-disteraoyl-phosphatidylcholine (DSPC) (solid state) phospholipids by using nanostructured lipid/peptide f

We studied monomolecular layers at the oil/water interface (O/W int ) in a Langmuir interfacial trough using egg-yolk phosphatidylcholine (EPC) (the model phospholipid) and Vaseline (VAS) as oil phase. The temporal dynamics in the surface pressure (�

The rheological properties of beta amyloid Langmuir monolayers: Comparative studies with melittin peptide

Autor: Gerardo D. Fidelio, Benjamín Caruso, Ernesto E. Ambroggio, Natalia Wilke

Publikováno v: Colloids and Surfaces B: Biointerfaces. 146:180-187

We determined the rheological properties of β-amyloid Langmuir films at the air/water interface, a peptide whose interfacial structure is extended β-sheet, and compared them with those of films composed of Melittin (Mel), which adopts an α-helical

The aim of the present work was to understand the interfacial properties of a complex mixture of wax esters (WEs) obtained from Jojoba oil (JO). Previously, on the basis of molecular area measurements, a hairpin structure was proposed as the hypothet

Phase coexistence in films composed of DLPC and DPPC: A comparison between different model membrane systems

Autor: Benjamín Caruso, Agustín Mangiarotti, Natalia Wilke

Publikováno v: Biochimica et Biophysica Acta (BBA) - Biomembranes. 1838:1823-1831

For the biophysical study of membranes, a variety of model systems have been used to measure the different parameters and to extract general principles concerning processes that may occur in cellular membranes. However, there are very few reports in

Probing the Combined Effect of Flunitrazepam and Lidocaine on the Stability and Organization of Bilayer Lipid Membranes. A Differential Scanning Calorimetry and Dynamic Light Scattering Study

Publikováno v: Cell Biochemistry and Biophysics. 66:461-475

Combined effects of flunitrazepam (FNZ) and lidocaine (LDC) were studied on the thermotropic equilibrium of dipalmitoyl phosphatidylcholine (dpPC) bilayers. This adds a thermodynamic dimension to previously reported geometric analysis in the erythroc

Reversing the peptide sequence impacts on molecular surface behaviour

Autor: Gerardo D. Fidelio, Benjamín Caruso, Vincent Raussens, Marcos Ariel Villarreal, Ernesto E. Ambroggio

The protein's primary structure has all the information for specific protein/peptide folding and, in many cases, can define specific amphiphilic regions along molecules that are important for interaction with membranes. In order to shed light on how

Inter-domain interactions in charged lipid monolayers

Autor: Benjamín Caruso, Marcos Ariel Villarreal, Natalia Wilke, Luis Reinaudi

Publikováno v: The journal of physical chemistry. B. 118(2)

Phase coexistence is common in model biomembranes with the presence of domains formed by lipids in a dense phase state modulating lateral diffusion of species through hydrodynamic and electrostatic interactions. In this study, interdomain interaction

Stiffness of lipid monolayers with phase coexistence

Autor: Natalia Wilke, Agustín Mangiarotti, Benjamín Caruso

Publikováno v: Langmuir : the ACS journal of surfaces and colloids. 29(34)

The surface dilational modulus (or compressibility modulus) has been previously studied for monolayers composed of pure materials, where a jump in this modulus was related with the onset of percolation as a result of the establishment of a connected
