Multilayer of Phospholipid Membranes on a Hydrosol Substrate [PDF]

open access: yesJETP Letters 92, 356 (2010), 2010
The molecular structure of a multilayer of 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC) adsorbed on the surface of the hydrosol of silica nanoparticles has been studied by the synchrotron radiation scattering method. According to the reflectometry data, the multilayer is formed by planar phospholipid bilayers with a thickness of 69 +/- 1 Angstrom ...

Phospholipid Scramblases [PDF]

open access: yesLipid Insights, 2015
The distribution of phospholipid types between the two leaflets of a membrane bilayer is a controlled feature of membrane structure. One of the two membrane catalytic activities governing this distribution randomizes the composition of the two leaflets–-the phospholipid scramblases.

Modulation of Macrophage Polarization by Phospholipids on the Surface of Titanium

open access: yesMolecules, 2020
Macrophage polarization has become increasingly important for the improvement of the biocompatibility of biomaterials. In this study, we coated Ti discs with phospholipids (phosphatidylserine/phosphatidylcholine [4:1 mole/mole]) by evaporating the ...

Disease-related PSS1 mutant impedes the formation and function of osteoclasts

open access: yesJournal of Lipid Research, 2023
Phosphatidylserine (PS) is an acidic phospholipid that is involved in various cellular events. Heterologous dominant mutations have been identified in the gene encoding PS synthase 1 (PSS1) in patients with a congenital disease called Lenz-Majewski ...

Phospholipids as ionophores. [PDF]

open access: yesJournal of Biological Chemistry, 1976
The ionophoretic capabilities of phospholipids have been examined by direct measurement in a Pressman cell of the phospholipid-mediated translocation of cations across an organic phase separating two aqueous phases. Cardiolipin and phosphatidic acid were the most active inonophores among the phospholipids tested, with activities comparable to that of ...

The power of microRNA regulation—insights into immunity and metabolism

open access: yesFEBS Letters, EarlyView.
MicroRNAs are emerging as crucial regulators at the intersection of metabolism and immunity. This review examines how miRNAs coordinate glucose and lipid metabolism while simultaneously modulating T‐cell development and immune responses. Moreover, it highlights how cutting‐edge artificial intelligence applications can identify miRNA biomarkers ...

Decoupling of dipolar and hydrophobic motions in biological membranes [PDF]

open access: yesarXiv, 2020
Cells use homeostatic mechanisms to maintain an optimal composition of distinct types of phospholipids in cellular membranes. The hydrophilic dipolar layer at the membrane interface, composed of phospholipid headgroups, regulates the interactions between cell membranes and incoming molecules, nanoparticles, and viruses.
