With our human gut - on - a-chip, we can not only culture the normal gut microbiome for extended times, but we can also analyze contributions of pathogens, immune cells, and vascular and lymphatic endothelium, as well as model specific diseases to understand complex pathophysiological responses of the intestinal tract.»

IDMIT will contribute 1) To the development and validation of assays based on flow cytometry and mass cytometry for the evaluation of immune responses in humans and animal models; these tools will be particularly relevant for the identification of signatures of vaccine efficacy; 2) To the animal model platform, in particularly by providing access to NHP models and to new technologies for in vivo imaging infections and host responses; 3) To networking activities, in particular by organising a workshop on in vivo imaging.

Such models are valuable for the analysis of parameters associated with vaccine safety, immunogenicity, delivery and protection as NHPs replicate key features of the human immune response more faithfully than any other animal model.

Hypothesis driven approaches to vaccinology can utilise the knowledge gained from mechanistic mouse models and our molecular understanding of intrinsic defects to human cells.5 However, caution is required when extrapolating data from murine models, as there are substantial differences between immune ageing in mice and humans.6 Nevertheless, model systems and ex vivo analyses of molecular alterations in aged human cells have identified multiple changes in the vaccination response with age and the aged immune system in general.

Our technological expertise ranges from the most fundamental approaches to study membrane transport in lymphocytes and dendritic cells (subcellular compartmentalization, intravital microscopy, phagosomal functions), the systematic analysis of gene expression and it regulation (RNAseq, Chip Seq, proteomics) and physiological and pathological immune responses (mouse models for cancer immunity, immunomodulation / vaccination, human clinical studies in cancer).

We chose this model because 1) it more closely recapitulates features of human pancreatic cancer than do s.c. - implanted tumors, 2) it can be used in immunocompetent mice to permit assessment of immune responses, and 3) the cells grow in vivo with predictable kinetics (34).

For understanding the biology of gene - gene, gene - drug and gene - microenvironment interactions, a considerably broader range of in vitro and in vivo model systems is required — we are generating 1,000 organoid cultures from human cancers, characterising their genomes, functional dependencies and drug response, and we are expanding our in vivo models to study the interface between cancer and the immune system and microenvironment.
