MetabolomicsMacrophage ATP citrate lyase deficiency stabilizes atherosclerotic plaques
Macrophages represent a major immune cell population in atherosclerotic plaques and play central role in the progression of this lipid-driven chronic inflammatory disease. Targeting immunometabolism is proposed as a strategy to revert aberrant macrophage activation to improve disease outcome. Here, ...

MetabolomicsCTH exacerbates Helicobacter pylori immunopathogenesis by promoting macrophage metabolic remodeling and activation
Macrophages play a crucial role in the inflammatory response to the human stomach pathogen Helicobacter pylori, which infects half of the world's population and causes gastric cancer. Recent studies have highlighted the importance of macrophage immunometabolism in their activation state and function...

MetabolomicsMacrophage-mediated antibiotic evasion and competitive dominance of mcr-3-carrying Escherichia coli

Mobile colistin resistance (mcr) genes undermine the efficacy of last-line polymyxin antibiotics, and the global prevalence of mcr-3 continues to rise despite reduced colistin use. Here, we show that mcr-3-positive Escherichia coli (E. coli) confers a survival advantage by reprogramming macrophag...

MetabolomicsAggressive breast cancers secrete heme metabolites to alter macrophage immune suppression and function
The heme catabolism pathway is often elevated in aggressive cancers; however, the impact of this pathway and some of its byproducts on the tumor microenvironment remain largely unknown. In human breast cancers, tumor expression of the heme catabolizing enzyme heme oxygenase-1 (HO-1/HMOX1) is positiv...

MetabolomicsSuccinate drives macrophage inflammation by promoting GPR91 mitochondrial signaling in rheumatoid arthritis

Succinate is implicated in rheumatoid arthritis (RA) and other inflammatory diseases via its receptor, G protein-coupled receptor 91 (GPR91). Despite its therapeutic potential, conflicting reports on its inflammatory roles have hindered GPR91-targeted treatm...

ProteomicsAbsolute Protein Quantitation of the Mouse Macrophage Toll-Like Receptor and Chemotaxis Pathways
The Toll-like receptor and chemotaxis pathways are key components of the innate immune system. Computational modeling and simulation at the molecular interaction level can be used to study complex biological pathways, but protein concentration values must be input as model parameters. In this invest...

MetabolomicsIntegrated transcriptomic and metabolomic analysis reveals the metabolic programming of GM-CSF-and M-CSF-differentiated mouse macrophages

Macrophages play a critical role in the inflammatory response and tumor development. Macrophages are primarily divided into pro-inflammatory M1-like and anti-inflammatory M2-like macrophages based on their activation status and functions. In vitro macrophage models could be derived from ...

MetabolomicsExogenous L-Alanine promotes phagocytosis multidrug-resistant bacterial pathogens (L-Alanine-treated macrophage metabolomics)

Multidrug-resistant bacteria present a major threat to public health. Therefore, new drugs or approaches are urgently needed to manage and mitigate this threat. Here, we screen the molecular candidates that allow the survival of mice upon Vibrio parahaemolyticus infection by integrated p...

MetabolomicsSalmonella Typhimurium reprograms macrophage metabolism via T3SS effector SopE2 to promote intracellular replication and virulence

Salmonella Typhimurium establishes systemic infection by replicating in host macrophages. Here we show that macrophages infected with S. Typhimurium exhibit upregulated glycolysis and decreased serine synthesis, leading to accumulation of glycolytic intermediates. The effects on...

MetabolomicsSpirulina Prevents Hepatic Steatosis by Promoting Macrophage M2 Polarization via Gut Microbiota-Derived 2-Hydroxy-3-Methylbutyrate
Background & Aims: Spirulina, a microalgae renowned for its nutrient density, shows promise in modulating glucose and lipid metabolism. However, its efficacy and underlying mechanisms against metabolic dysfunction-associated steatotic liver disease (MASLD) remain unclear. We hypothesized that spirul...
