MetabolomicsBranched-chain ketoacids derived from cancer cells modulate macrophage polarization and metabolic reprogramming

Macrophages are prominent immune cells in the tumor microenvironment that can be educated into pro-tumoral phenotype by tumor cells to favor tumor growth and metastasis. The mechanisms that mediate a mutualistic relationship between tumor cells and macrophages remain poorly characterized. Here, w...

MetabolomicsModel-driven multi-omic data analysis elucidates metabolic immunomodulators of macrophage activation
Macrophages are central players in immune response, manifesting divergent phenotypes to control inflammation and innate immunity through release of cytokines and other signaling factors. Recently, the focus on metabolism has been reemphasized as critical signaling and regulatory pathways of human pa...

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...

MetabolomicsAn Atlas of Ferroptosis-induced Secretomes promotes Macrophage priming
Cells undergoing regulated necrosis systemically communicate with the immune system via release of protein and non-protein secretomes. Ferroptosis is a recently described iron-dependent type of regulated necrosis driven by massive lipid peroxidation. While membrane rupture occurs during ferroptosis,...

TranscriptomicsTranscriptome-based network analysis reveals a spectrum model of human macrophage activation [miRNA-seq]
Macrophage activation is associated with profound transcriptional reprogramming. Although much progress has been made in the understanding of macrophage activation, polarization and function, the transcriptional programs regulating these processes remain poorly characterized. We stimulated human mac...

TranscriptomicsTranscriptional profiling of primary human macrophages with different stimuli
Primary human macrophages were cultured 1, 3 or 6 days with different stimuli. Macrophages are key cell types of the innate immune system regulating host defense, inflammation, tissue homeostasis and cancer. Within this functional spectrum diverse and often opposing phenotypes are displayed which ar...

TranscriptomicsModulation of the TNF-induced macrophage response by synovial fibroblasts
Here we explored how the human macrophage response to tumor necrosis factor (TNF) is regulated by human synovial fibroblasts, the representative stromal cell type in the synovial lining of joints that become activated during inflammatory arthritis. Genome-wide transcriptome analysis (RNAseq) showed ...

MetabolomicsGPR109a-AMPK Axis Mediates the Attenuation of Uric Acid-Induced M1 Macrophage Polarization by β-hydroxybutyrate from Lacticaseibacillus rhamnosus M2b

Hyperuricemia (HUA) is a metabolic disorder marked by increased blood uric acid (UA) levels, closely linked to conditions such as gout. UA-induced macrophage M1 polarization fundamentally exacerbates inflammatory pathophysiology, but current HUA-specific immunoregulatory treatments are inadequat...

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...
