On the role of surrounding regions in the fusion peptide in dengue virus infection
(2021-05-01)
Dengue virus infection depends on its fusion with the host membrane, where the binding occurs through interaction between proteins on the virus cell surface and specific viral receptors on target membranes. This process ...
Penicillin-binding proteins (PBPs) determine antibiotic action in Langmuir monolayers as nanoarchitectonics mimetic membranes of methicillin-resistant Staphylococcus aureus
(2022-06-01)
The membrane of methicillin-resistant Staphylococcus aureus (MRSA) contains penicillin-binding proteins (PBPs) in the phospholipidic bilayer, with the protein PBP2a being linked with the resistance mechanism. In this work ...
The insertion of Polybia-MP1 peptide into phospholipid monolayers is regulated by its anionic nature and phase state
(Elsevier Ireland, 2017-10)
Polybia-MP1 or simply MP1 (IDWKKLLDAAKQIL-NH2) is a peptide with broad-spectrum bactericidal activity and a strong inhibitory effect against cancer cells. The aim of this work was to evaluate the effect of biophysical ...

Refractive index and thickness determination in Langmuir monolayers of myelin lipids
(Elsevier Science, 2017-05)
Langmuir monolayers at the air/water interface are widely used as biomembrane models and for amphiphilic molecules studies in general. Under controlled intermolecular organization (lateral molecular area), surface pressure, ...
Distinctive Interactions of Oleic Acid Covered Magnetic Nanoparticles with Saturated and Unsaturated Phospholipids in Langmuir Monolayers
(American Chemical Society, 2014-04)
The growing number of innovations in nanomedicine and nanobiotechnology are posing new challenges in understanding the full spectrum of interactions between nanomateriales and biomolecules at nano-biointerfaces. Although ...
Surface behavior of sphingomyelins with very long chain polyunsaturated fatty acids and effects of their conversion to ceramides
(American Chemical Society, 2014-03)
Molecular species of sphingomyelin (SM) with nonhydroxy (n) and 2-hydroxy (h) verylong-chain polyunsaturated fatty acids (n- and h-28:4, 30:5 and 32:5) abound in rat spermatogenic cells and spermatozoa. These SMs are located ...
The many faces (and phases) of ceramide and sphingomyelin I – single lipids
(Springer Verlag, 2017-10)
Ceramides, the simplest kind of two-chained sphingolipids, contain a single hydroxyl group in position 1 of the sphingoid base. Sphingomyelins further contain a phosphocholine group at the OH of position 1 of ceramide. ...
The specificity of frutalin lectin using biomembrane models
(ELSEVIER SCIENCE BV, 2010)
Frutalin is a homotetrameric alpha-D-galactose (D-Gal)-binding lectin that activates natural killer cells in vitro and promotes leukocyte migration in vivo. Because lectins are potent lymphocyte stimulators, understanding ...
