Agonist mobility on supported lipid bilayers affects Fas mediated death response
(Elsevier Science, 2015-11-30)
Extrinsic apoptosis is initiated by recognition and clustering of the single-pass transmembrane proteins Fas ligand and Fas expressed at the surface of closely apposed lymphocytes and target cells, respectively. Since ...
Lipid Droplets: Structure, Composition, Formation and Function. Connection with the Endoplasmic Reticulum
(Nova Science Publishers, 2019)
Fatty acids (FAs) are important compounds either used for energy production through β-oxidation, for membrane lipid synthesis, or for production of lipid mediators (oxylipins) through oxidations. FAs are also cytotoxic and ...
Lipid hydroperoxidation effect on the dynamical evolution of the conductance process in bilayer lipid membranes: A condition toward criticality
(American Chemical Society, 2020-08-04)
Cell membranes are one of the main targets of oxidative processes mediated by reactive oxygen species (ROS). These chemical species interact with unsaturated fatty acids of membrane lipids, triggering an autocatalytic chain ...
The fat body of the hematophagous insect, panstrongylus megistus (Hemiptera: Reduviidae): Histological features and participation of the β-chain of ATP synthase in the lipophorin-mediated lipid transfer
(University of Arizona, 2019-07)
In insects, lipid transfer to the tissues is mediated by lipophorin, the major circulating lipoprotein, mainly through a nonendocytic pathway involving docking receptors. Currently, the role of such receptors in lipid ...
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 ...
Juvenile hormone mediates lipid storage in the oocytes of Dipetalogaster maxima
(Elsevier, 2020-11-16)
Triatomines are vectors of Chagas disease and important model organisms in insect physiology. “Kissing bugs” are obligatory hematophagous insects. A blood meal is required to successfully complete oogenesis, a process ...
Anandamide revisited: How cholesterol and ceramides control receptor-dependent and receptor-independent signal transmission pathways of a lipid neurotransmitter
(MDPI, 2018-06)
Anandamide is a lipid neurotransmitter derived from arachidonic acid, a polyunsaturated fatty acid. The chemical differences between anandamide and arachidonic acid result in a slightly enhanced solubility in water and ...
