Gut-Liver-Brain Axis Research to Improve Metabolic Health "GLoBAL"
(腸肝脳相関研究;現在進行中プロジェクト、参画企業・団体募集中)
● Overview;
Investigation of Gut-Liver-Brain Axis in severe obese patients undergoing bariatric surgery(~n=150) with extensive characterization of tissue biopsies and systems biology.
Extensive neuroimaging (MRI), cognition tests, plasma and microbiota analysis over time (pre-operation, hospitalization and post-operation).
● Readout and Samples;
> Brain; Cognition, Behaviour test, Brain fMRI scan
> Samples (n=500)
> Tissue; Liver, Adipose tissue, Jejunam.
> Plasma; Lipidomics, Adipokine, Hepatokines, Bile acids, etc.
> Microbiota; Feces, Mucosal swab; Stomach, Jejunam
● Tests conducted;
> NeuroPhysiological test; MoCA, COWAT, IQ, Working memory, Episodic memory, TAP.
> Behaviour; Scores of Impulsivity, Motivation, Depression, GI complaint, etc
> GI complaints (e.g. GSRS and IBS-SSS scores) to evaluate diarrhea, obstipation and others
● Invitation to analyse specific health aspect using the samples in stock as the followings;
> Liver (histology, transcriptomics)
> Visceral adipose tissues
> Jejunum, gut permeability
> Mucosal & feces microbiota
> Plasma
> SCFA, amino acids, lipids, bile acids, Vitamins, etc
● Opportunities to assess relation between MB and Brain
> Choose interaction of interest (e.g. microbiota to long-term memory, or gut permeability to cognition tests)
> Use available data or eventually measure additional parameters
> Check for correlations or associations
> Identify critical body parameters that correlate with brain health
