Gut bacteria-host metabolic interplay during conventionalisation of the mouse germfree colon. Featured in Chemisch2Weekblad Dutch. We hypothesize that the gut microbiota can metabolize neuro-amines produced from the host and its diet to subsequently produce neuroactive metabolites, thus contribute to signaling to the host gut-brain axis.

Adv Sahar el aidy thesis Med Biol. He also identified and characterized a novel sequence for lipid-anchoring by fluorescence spectroscopy techniques.

Can the gut microbiota metabolize these neuro-amines? In a recent bioinformatics study Frans and coworkers revealed that MHC-I epitopes are several-fold enriched in transmembrane helices depending on the haplotype.

The gut microbiota elicits a profound metabolic reorientation in the mouse jejunal mucosa during conventionalisation. Furthermore, we showed that the microbiota strongly affects the glucose and energy metabolism of the proximal part of small intestine, namely, the jejunum 4.

The microbiota and the gut-brain axis: Temporal and spatial interplay of microbiota and intestinal mucosa drive establishment of immune homeostasis in conventionalized mice.

Metabolites of the microbiota are key part in the feed- back loop, mediating of gene-environment interactions 7 An additional insight from the temporal and spatial mucosal alterations during colonisation of the GF mouse intestine, was our finding indicating the response of the enteric nervous system to microbial colonization appears to be postponed during the process of microbial colonization until a microbiota-accommodating state of immune and metabolic homeostasis is established 5.

These signaling molecules, such as neuroactive chemicals, in particular neuro-amines, seem to play a key role in shuttling information between the host and its microbiota. This so-called microbiota has co-evolved with man to perform a number of beneficial functions; these extend beyond the gastrointestinal tract to influence host behaviour and mental health.

Can the gut microbiota sense neuro-amines from the host? The gradual development of the adaptive immune system appeared to follow a strong but transient hyper-induction of innate immune responses, including high-level production of antimicrobial peptides1, 2. Colonization of the gut microbiota launches complex communication networks with the host immune, metabolic and neuroendocrine systems, which ultimately impacts the overall wellbeing of the host organism 6.

Research outline aiming to unravel To test our hypothesis, we address 3 main questions summarised in figure 3-for details see the potential projects within Join the lab: During his PhD, Frans studied the mobility, oligomerization and localization of plasma membrane-incorporated amino acid transporters in budding yeast using advanced microscopy and spectroscopy techniques single particle tracking, super-resolution microscopy, circular dichroism.

The metabolic dialogue between the microbiota and host cells involves small molecule signaling metabolites, peptides and proteins.

Previously, we have identified the molecular mechanisms involved in the reprogramming of the intestinal mucosal immune responses to initiate and maintain a balanced immune response. The latest updated list of publications by Frans Bianchi can be found here. Finally, he compared transport fluxes of eukaryotic and prokaryotic basic amino acid transporters using reconstituted proteins in proteo-liposomes with radioactively labeled substrate.

Similarly, we revealed that only the establishment of a balanced microbial community could deplete high-energy metabolites and generate second-stage fermentation short chain fatty acids that can be efficiently metabolised by colonic epithelia 3.

The small intestine microbiota, nutritional modulation and relevance for health. He showed that the localization of these plasma membrane proteins in S. Unravelling the Multidirectional Axes of Communication. Therefore, to build on our existing knowledge of microbiota-host immune, metabolic anf neuroal cross-talk summerized in Figure 1 ; we are currently focusing on unraveling the metabolic dialogue between the microbiota and its host gut-brain interphase Figure 2.

Furthermore, he identified that steric interactions of large cytosolic domains form the predominant barrier of this impaired lateral diffusion.
