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...

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...

MetabolomicsProphylactic and therapeutic itaconate treatment alleviates COVID-19-associated lung injury

Although itaconate demonstrates anti-inflammatory and antimicrobial properties as an immunomodulatory metabolite, the therapeutic potential and mechanistic basis of vaccine-induced or prophylactic itaconate administration in COVID-19 intervention remains underexplored. Our studies reveal that int...

MetabolomicsAtractylodin targets ASAH3L to regulate galactose metabolism and thereby modulates the HIF-1 signaling pathway for the treatment of acute lung injury

Acute lung injury (ALI) is a lung disease characterized by an excessive inflammatory response and damage to lung epithelial cells. Atractylodin (ATL) is the main active component of Atractylodes lancea (Thunb.) DC., which has good anti-inflammatory activity and protects the integrity of the epith...

MetabolomicsFunctional Remodeling of iNKT Cells by Sulfatide-Reactive Type II NKT Cells Reprograms Alveolar Macrophages to Alleviate Lung Ischemia-Reperfusion Injury

Lung ischemia-reperfusion injury (LIRI) is a serious complication in critical clinical situations. Despite its importance, the specific role of type II natural killer T (NKT) cells in LIRI remains unclear. In this study, we establish a LIRI mouse model and demonstrate that sulfatide-reactive type...

TranscriptomicsCavin1 Deficiency Alters Lung macrophage homeostasis in Mouse
Caveolae are cell membrane invaginations that are highly abundant in adipose tissue, endothelial cells and lung and are present at lower levels in other tissues. The formation of caveolae is dependent of the expression of various structural proteins that serve as scaffolding for these membrane invag...

TranscriptomicsExpression Profiling of Macrophages Reveals Multiple Populations with Distinct Biological Roles in an Immunocompetent Orthotopic Model of Lung Cancer
Macrophages represent an important component of the tumor microenvironment and play a complex role in cancer progression. These cells are characterized by a high degree of plasticity, and alter their phenotype in response to local environmental cues. While the M1/M2 classification of macrophages has...

MetabolomicsIntegrated pharmacological and metabolomic characterization of a polysaccharide-enriched fraction from Qingfei-Paidu Decoction for protection against acute lung injury in mice
The formula of Qingfei-Paidu Decoction was separated into a polysaccharide-enriched fraction (PSC) and an ethanol-soluble small-molecule fraction (EtOH), whose biological activities were systematically compared under equivalent crude drug conditions using an LPS-induced ALI mouse model and macrophag...

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...

TranscriptomicsMouse GM-CSF-related alveolar macrophage genome-wide expression data
GM-CSF receptor-β deficient (Csf2rb–/– or KO) mice develop a lung disease identical to hereditary pulmonary alveolar proteinosis (hPAP) in humans with recessive CSF2RA or CSF2RB mutations that impair GM-CSF receptor function. We performed pulmonary macrophage transplantation (PMT) of bone marro...
