Incorporation of Novel Synthetic Glycolipids in Liposomal Nanoparticles Affects Opsonization and In Vivo Clearance

Angewandte Chemie International Edition, EarlyView.
We prepared five glycosylated liposomal nanoparticles (G‐LNPs) to investigate the role of glycosylation and protein corona in modulating the in vivo behavior of G‐LNPs. We show that IgG and complement C3 adsorption enhanced liposomal nanoparticle clearance, with IgG promoting subsequent C3 binding.

Putting the pH into phosphatidic acid signaling

BMC Biology, 2011
The lipid phosphatidic acid (PA) has important roles in cell signaling and metabolic regulation in all organisms. New evidence indicates that PA also has an unprecedented role as a pH biosensor, coupling changes in pH to intracellular signaling pathways.

Phosphatidic Acid Accumulates at Areas of Curvature in Tubulated Lipid Bilayers and Liposomes

Biomolecules, 2022
Phosphatidic acid (PA) is a signaling lipid that is produced enzymatically from phosphatidylcholine (PC), lysophosphatidic acid, or diacylglycerol. Compared to PC, PA lacks a choline moiety on the headgroup, making the headgroup smaller than that of PC ...

Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine

BMEMat, EarlyView.
Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

Nuclear Entanglement: New Insights Into the Role of Cytoskeleton and Nucleoskeleton in Plant Nuclear Function

Cytoskeleton, EarlyView.
ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Levels of Arabidopsis thaliana leaf phosphatidic acids, phosphatidylserines, and most trienoate-containing polar lipid molecular species increase during the dark period of the diurnal cycle

Frontiers in Plant Science, 2012
Previous work has demonstrated that plant leaf polar lipid fatty acid composition varies during the diurnal (dark-light) cycle. Fatty acid synthesis occurs primarily during the light, but fatty acid desaturation continues in the absence of light ...

Aloe vera in Food Preservation: Harnessing Bioactive Constituents for Clean‐Label Innovation and Safety Assurance

Food Safety and Health, EarlyView.
Aloe vera‐derived biopolymers and nanoformulations enhance antimicrobial, antioxidant, and barrier functions in clean‐label edible coatings and films, whereas safety‐critical anthraquinone thresholds and regulatory constraints shape their translational potential.

6-PPD Quinone Inhibits Phosphatidic Acid Synthesis Associated with an Increase in Intestinal Barrier Permeability in C. elegans

Toxics
6-PPD quinine (6-PPDQ) affects intestinal barrier function; however, its underlying mechanisms remain largely unknown. In the current study, we examined the role of reduction in phosphatidic acid synthesis in mediating the toxicity of 6-PPDQ in affecting

AGPAT2 interaction with CDP-diacylglycerol synthases promotes the flux of fatty acids through the CDP-diacylglycerol pathway

Nature Communications, 2021
AGPATs (1-acylglycerol-3-phosphate O-acyltransferases) catalyze the acylation of lysophosphatidic acid to form phosphatidic acid (PA), a key step in the synthesis of all glycerolipids.

Regulation of mTOR by Phosphatidic Acid? [PDF]

Cancer Research, 2007
Abstract Interest in the regulation of the mammalian target of rapamycin (mTOR) has increased substantially in recent years largely because of an apparent link between mTOR and survival signals in human cancer cells. Much has been learned about the regulation of mTOR in response to survival signals generated by phosphatidylinositol 3 ...
