Phospholipid Scramblases [PDF]
Lipid 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.

Thermodynamic Approach to Phase Coexistence in Ternary Phospholipi-Cholesterol Mixtures [PDF]
Physical Review Letters 106 (2011) 128104, 2011 We introduce a simple and predictive model for determining the phase stability of ternary phospholipid-cholesterol mixtures. Assuming that competition between the liquid and gel order of the phospholipids is the main driving force behind lipid segregation, we derive a Gibbs free-energy of mixing, based on the thermodynamic properties of the lipids main

Interaction of Small Ionic Species With Phospholipid Membranes: The Role of Metal Coordination
Frontiers in Materials, 2019 In studies of the transfer, distribution and biochemical activity of metal ions it is typically assumed that the phospholipid bilayer acts as an inert barrier.

Phospholipids as ionophores. [PDF]
Journal 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
FEBS 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]
arXiv, 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.

Putting the 'P' into Phospholipids
CHIMIA, 2011 Despite almost hundred years of dedicated research, the synthesis of phospholipids remains a challenge. Here, we briefly review important trends and point out possible future directions that might lead to interesting new probes for the membrane environment. An improved liposome purification and concentration protocol rounds up the article.
