Membrane‐Active Peptide Protects Against Inflammation by Targeting NLRP3 Activation at the Trans‐Golgi Network

Advanced Science, EarlyView.
The membrane‐active peptide Pep19‐2.5 reduces harmful inflammation by blocking activation of the NLRP3 inflammasome at trans‐Golgi network membranes. By targeting key membrane interactions, Pep19‐2.5 suppresses inflammatory IL‐1β production and alleviates allergic airway inflammation in mice, leading to reduced immune cell infiltration and improved ...

Postresuscitative Effects of Mexidole on Myocardial Lipid Composition and Perioxidation

Общая реаниматология, 2005
An experimental model of clinical death followed by reperfusion was used to study the postresuscitative effects of the anti-hypoxant mexidole on lipid composition and peroxidation rates in the rat myocardium.

Lyssavirus Nucleoprotein Induces GPAT4‐Mediated CYB5R1 Depalmitoylation to Suppress Ferroptosis and Promote Viral Replication

Advanced Science, EarlyView.
Lipid metabolism plays a vital role in viral infections. Here, we reveal that the lyssavirus N protein regulates GPAT4 to induce lipid droplet biogenesis, restricting CYB5R1 palmitoylation and reducing ferroptosis susceptibility to ultimately promote viral replication.

Lipid sensing by mTOR complexes via de novo synthesis of phosphatidic acid

Journal of Biological Chemistry, 2017
mTOR, the mammalian target of rapamycin, integrates growth factor and nutrient signals to promote a transformation from catabolic to anabolic metabolism, cell growth, and cell cycle progression.

Dual Repression by IPA1 Fine‐Tunes OsbZIP79‐Mediated Salt Tolerance in Rice

Advanced Science, EarlyView.
Dual repression by IPA1 fine‐tunes OsbZIP79‐mediated salt tolerance in rice: direct transcriptional inhibition under normal conditions and salt‐induced degradation under stress. This dual mechanism activates OsbZIP79 to regulate Na+/K+ homeostasis and redox balance via downstream genes, enabling optimal salt stress response.

The liver‐brain axis: A multidimensional regulatory network implicated in Alzheimer's disease pathogenesis and clinical implications

Animal Models and Experimental Medicine, EarlyView.
Schematic diagram of the core pathways of the liver‐brain axis in regulating AD. The liver regulates cerebral Aβ deposition, tau phosphorylation, and neuroinflammation through pathways such as metabolic detoxification (urea cycle, ketone body metabolism, glutathione antioxidant system), molecular secretion (APOE, CRP, FGF21, IGF‐1), and Aβ clearance ...

Apicoplast-Localized Lysophosphatidic Acid Precursor Assembly Is Required for Bulk Phospholipid Synthesis in Toxoplasma gondii and Relies on an Algal/Plant-Like Glycerol 3-Phosphate Acyltransferase.

PLoS Pathogens, 2016
Most apicomplexan parasites possess a non-photosynthetic plastid (the apicoplast), which harbors enzymes for a number of metabolic pathways, including a prokaryotic type II fatty acid synthesis (FASII) pathway.

Cellular Uptake, Metabolism and Sensing of Long-Chain Fatty Acids

Frontiers in Bioscience-Landmark, 2023
Fatty acids (FAs) are critical nutrients that regulate an organism’s health and development in mammal. Long-chain fatty acids (LCFAs) can be divided into saturated and unsaturated fatty acids, depending on whether the carbon chain contains at least 1 ...

A Role for Phosphatidic Acid in the Formation of “Supersized” Lipid Droplets

PLoS Genetics, 2011
Lipid droplets (LDs) are important cellular organelles that govern the storage and turnover of lipids. Little is known about how the size of LDs is controlled, although LDs of diverse sizes have been observed in different tissues and under different ...
