Feedback-control of the Microenvironment: Modular Organ-on-Chip Technology to elucidate the role of Neurovascular Stress in Schizophrenia

Introduction

A well-controlled microenvironment is paramount for reproducible biomolecular studies. Organs-on-chips are in-vitro cell culture systems that employ microfluidic and biomaterial engineering towards that goal. They combine the advantages of animal models (physiological environment) with those of plastic-dish culture (human cells), and thereby hold exceptional promise in unraveling the biological processes that underlie health and disease. Yet control over the biochemical environment remains poor.

Project Proposal

With CHIPzophrenia, I propose to develop a new generation of organ-chip, one that features feedback-enabled control of the biochemical environment. I aim to realize dynamic and well-controlled application of stable therapeutics (via feedback sensors and flow control), and crucially also of highly volatile oxygen/nitrogen stressors by relying on electrochemistry to generate them in situ.

System Architecture

My goal is to implement a highly functional modular architecture so that the system can easily be repurposed and sensor/control modules reused – all with negligible dead volumes and displacement (key challenges in current organ-chips towards novel functionalities).

Research Focus

I intend to leverage this organ-chip to elucidate how nitrosative stressors disrupt the complex multicellular interactions of the blood-brain barrier, where existing in-vitro models fail to provide the requisite cellular and chemical microenvironment.

Implications of Research

Such disruption is implicated in a wide array of disorders – including schizophrenia, where our biological understanding remains poor and in-vivo models are uniquely challenging. I will specifically test the hypothesis that nitrosative dysregulation of perivascular cells plays a causative role in neuronal dysfunction associated with the disorder.

Conclusion

Not only will CHIPzophrenia thus reveal new potential treatment targets, but it will also establish the platform as a transformative tool for dynamic and well-controlled in-vitro research into stress-related disorders and beyond.
