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...

MetabolomicsHypusination Orchestrates the Antimicrobial Response of Macrophages
Innate responses of myeloid cells defend against pathogenic bacteria via inducible effectors. Deoxyhypusine synthase (DHPS) catalyzes the transfer of the N-moiety of spermidine to the lysine-50 residue of eukaryotic translation initiation factor 5A (EIF5A) to form the amino acid hypusine. Hypusinate...

TranscriptomicsDevelopment of Helicobacter pylori microarrays to test pathogenicity of clinical isolates
To distinguish between Helicobacter pylori isolates that may cause greater disease in patients, we used whole genome expression profiling as a platform to study host-pathogen interactions and identify gene signatures associated with isolates from patients with higher cancer risk. Expression profiles...

MetabolomicsOrnithine Decarboxylase in Gastric Epithelial Cells Promotes the Immunopathogenesis of Helicobacter pylori Infection

Colonization by H. pylori is associated with a wide range of gastric diseases, ranging from superficial gastritis to more severe pathologies, including intestinal metaplasia and adenocarcinoma. The interplay of the host response and the pathogen affect the outcome of disease. One major component ...

TranscriptomicsExpression data from murine colon tissue after exposure to 4% DSS for 6 days DSS followed by 4 days of water or 1% L-arginine
L-Arginine (L-Arg) is the substrate for both inducible nitric oxide synthase and arginase, which are upregulated in human IBD and in mouse colitis models. We have found that L-Arg supplementation enhances wound restitution in vitro, and improves the clinical parameters of weight loss, survival, and ...

MetabolomicsBacterial Pathogens Hijack the Innate Immune Response by Activation of the Reverse Transsulfuration Pathway

The reverse transsulfuration pathway is the major route for the metabolism of sulfur-containing amino acids. The role of this metabolic pathway in macrophage response and function is unknown. We show that the enzyme cystathionine γ-lyase (CTH) is induced in macrophages infected with pathogenic ba...
