MetabolomicsEctopic intestinal colonization by an oral commensal promotes C. difficile infection in Crohn’s disease
Crohn’s disease is a severe inflammatory disorder of the intestine for which there is no cure. People suffering from Crohn’s disease are at increased risk of developing Clostridioides difficile infection (CDI), which considerably exacerbates symptoms. Using a prospective observational clinical study...

MetabolomicsImpact of oral Chlamydia Vaccination on Host Gut Microbiome and Metabolite Composition

Chlamydia trachomatis, an intracellular pathogen, is recognized as the most common sexually transmitted bacterial infection among women worldwide. Chlamydia infections can lead to undesirable clinical outcomes, including pelvic inflammatory disease and infertility. Recently, the gut has been...

MetabolomicsOral Engineered Microalgae- Biosystem Targeting Intestinal Villi for Irritable Bowel Syndrome
Irritable Bowel Syndrome (IBS) is a chronic gastrointestinal disorder associated with dysregulation of the gut-brain axis. Current treatment approaches often lack long-term efficacy and target specificity, and there are no drugs or formulations specifically targeting this disease. Owing to chronic a...

MetabolomicsA Multi-Omic View of Host-Pathogen-Commensal Interplay in Salmonella-Mediated Intestinal Infection
The potential for commensal microorganisms indigenous to a host (the microbiome or microbiota) to alter infection outcome by influencing host-pathogen interplay is largely unknown. We used a multi-omics systems approach, incorporating proteomics, metabolomics, glycomics, and metagenomics, to explore...

MetabolomicsUntargeted lipidomics reveals colonic lipid alterations in C57BL/6J mice with acute Toxoplasma gondii infection

Although Toxoplasma gondii has been recognized as an obligate intracellular parasite, the lipid metabolic alterations it induces in colonic contents during acute infection remain poorly characterized. This study generated an acute infection model using C57BL/6J mice by oral inoculation with the T...

MetabolomicsEffects of oral ketone ester administration in a pMCAO model (KetoSTROKE study)

Rapid, deep, and sustained systemic ketosis was achieved using an orally administered ketone ester (KE: 3.0 mg/g body weight of (R)-3-hydroxybutyl (R)-3-hydroxybutyrate; DeltaG® Ketone Ester, TΔS® Ltd, Oxfordshire, UK) compared with control (0.9% NaCl) prior to permanent middle cerebral artery oc...

TranscriptomicsResponse of Henle 407 cells during Toxoplasma gondii infection
The innate immune response of mucosal epithelial cells during pathogen invasion plays a central role in immune regulation in the gut. Toxoplasma gondii (T. gondii) is a protozoan intracellular parasite that is usually transmitted through oral infection. Although much of the information on immunity...

MetabolomicsBioactivities of Streptomyces spp. Against selected Oral Pathogens and In silico Streptenol B interaction on pgaB of Aggregatibacter actinomycetemcomitans
Periodontal disease is an inflammatory condition affecting the tissues supporting the teeth. Biofilm formation by oral pathogens such as Aggregatibacter actinomycetemcomitans (AA) and Pseudomonas aeruginosa (PA) contribute to persistent infections and antibiotic resistance. This study evaluated the ...

MetabolomicsInfluenza A virus H1N1 infection alters sphingolipid metabolism in A549 cells
This study investigates metabolic alterations in A549 cells infected with influenza A virus H1N1 (WSN strain). Untargeted metabolomics analysis was performed using liquid chromatography coupled with mass spectrometry (LC-MS) in both positive and negative ionization modes. The study aims to character...

TranscriptomicsMethylationEPIC array from fresh oral and oropharyngeal tissue samples from head and neck squamous cell carcinoma patients, tissue samples from potentially premalignant oral lesions and fresh tonsil tissue samples from control patients
This data was used to detect good biomarkers for head and neck squamous cell carcinoma and was integrated with transcriptome and miRNome data aiming to elucidate role of epigenetics on gene expression in head and neck squamous cell carcinoma.
