Filling gaps in the knowledge of melittin on lipid membranes
(Elsevier Science, 2019-01-21)
Melittin (ML) is a small peptide of 26 residues rich in arginine (Arg) and lysine (Lys). Several studies have been done to understand the mechanism of interaction with neutral and negatively charged lipids. However, it is ...
Regulation of plasma membrane Ca 2 +-ATPase activity by acetylated tubulin: Influence of the lipid environment
(Elsevier Science, 2012-03)
We demonstrated previously that acetylated tubulin inhibits plasma membrane Ca 2 +-ATPase (PMCA) activity in plasma membrane vesicles (PMVs) of rat brain through a reversible interaction. Dissociation of the PMCA/tubulin ...
The lipid habitats of neurotransmitter receptors in brain
(Elsevier Science, 2016-11)
Neurotransmitter receptors, the macromolecules specialized in decoding the chemical signals encrypted in the chemical signaling mechanism in the nervous system, occur either at the somatic cell surface of chemically excitable ...
Control of membrane lipid homeostasis by lipid-bilayer associated sensors: A mechanism conserved from bacteria to humans
(Pergamon-Elsevier Science Ltd, 2019-10)
The lipid composition of biological membranes is key for cell viability. Nevertheless, and despite their central role in cell function, our understanding of membrane physiology continues to lag behind most other aspects ...
Modelling phagosomal lipid networks that regulate actin assembly
(BioMed Central, 2008-12)
Background: When purified phagosomes are incubated in the presence of actin under appropriate conditions, microfilaments start growing from the membrane in a process that is affected by ATP and the lipid composition of the ...
uPA binding increases UPAR localization to lipid rafts and modifies the receptor microdomain composition
(Elsevier Science, 2008-01)
UPAR is a GPI anchored protein, which is found in both lipid rafts and in more fluid regions of the plasma membrane. We have studied the role of the ligand uPA on uPAR localization and on the composition of the lipid ...
Comparative study of tear lipid composition in two human populations with different exposure to particulate matter in La Plata, Argentina
(Springer Heidelberg, 2019-03)
To identify the changes in the lipid profile of the tear film in two human populations exposed to different levels of particulate material, and its relationship with dry eye, by gas chromatography with mass spectrometry ...
Lipid quality of the diatoms Skeletonema costatum and Navicula gregaria from the South Atlantic Coast (Argentina): Evaluation of its suitability as biodiesel feedstock
(Springer, 2012-01-05)
Since the fatty acid ester profile of a given biofuel is relatively consistent with the source's fatty acid profile, the properties of the biodiesel produced from a particular feedstock exhibit predictable quality. Thus, ...
Lipid profiling by electrospray ionization tandem mass spectrometry and the identification of lipid phosphorylation by kinases in potato stolons
(American Chemical Society, 2011-12-05)
There is limited information about the involvement of lipids and esterified fatty acids in signaling pathways during plant development. The purpose of this study was to evaluate the lipid composition and molecular species ...
Sex and reproductive cycle affect lipid and fatty acid profiles of gonads of Arbacia dufresnii (Echinodermata: Echinoidea)
(Inter-Research, 2016-06-09)
Analysis of the lipid composition of gonads allows differentiation between energy and structural lipids, which is important for understanding lipid utilization during gametogenesis. Fatty acids, which are frequently used ...
