Full textWe have developed an enzyme immunosensor for the amperometric detection of alpha-fetoprotein with which repeated measures may be practised without exchanging the solid phase. Two different systems have been compared : the antibodies are either irreversibility bound to the gelatin membrane or reversibility bound using a p-aminophenyl-beta-D-thiogalactopyranoside (PAPTG) covalently bound membrane and IgG-beta-D-galactosidase complexes. Each system of detection is simple, easy to handle and possesses great possibilities for automation. The obtained sensitivity (0,5 ng/ml) is essentially effected by the choice of catalase as marker enzyme. It was shown that the system in which the antibodies are reversibly bound has a longer lifetime because the membranes are less susceptible to denaturation. Furthermore, the measurement time is shorter (5 minutes instead of 15) because then antigen!antibody reaction which is time consuming does not occur on the immunosensor. These two advantages further the utilization of this last system

Full textOver the past 4 decades, an intermediate model between the traditional in vivo and in vitro approaches has emerged: the MicroPhysiological Systems (MPS). MPS are designed to recapitulate different levels of human physiology, from the single organ to organs crosstalk. They upgrade the culture environment by patterning microstructures hosting 3D and multicellular architecture models and integrate microsensors monitoring cell activity and environment.This new investigation tool is of interest in fundamental research on diseases such as diabetes. In this incurable disease, blood glucose regulation, resulting from a complex organs interplay between the pancreatic islets, the liver, the adipocytes and the muscles, is impaired. A Multi-Organ-on-a-Chip (MOoC) is a MPS that can recapitulate these organs crosstalk and represents a relevant model for diabetes research. Indeed, inter-organ regulations are not recapitulated by usual in vitro models, and deciphering these interactions requires multiple sensors, which is not ethically and technically possible in vivo. In the context of diabetes, MOoCs reproducing the islets to skeletal muscles communication do not exist so far, despite the importance of the skeletal muscles impact on blood glucose, under islets action.In this thesis, we propose a methodology to design a MOoC deciphering islets to muscles interactions in blood glucose regulation. The MOoC objectives were to: (i) attain physiological insulin concentration secreted by islets in response to physiological glucose elevation, (ii) that induces a measurable glucose uptake by the muscle cells, (iii) monitor online relevant parameters. To that end, the investigations were conducted with an interdisciplinary approach, using and confronting results from both in vitro biological experiments and in silico modelling of biology and physics.This manuscript details the methodology steps, delivering different designs for progressive validation toward a complete MOoC that comprises a microfluidic chip with cells and an online glucose sensor. During the MOoC construction, our main findings were the following:- A co-culture medium and procedure for primary islets and LHCN-M2 myotubes were demonstrated.- A common MicroElectrodes Array-based substrate was found suited for co-culture in a single microfluidic chip.- Islets were cultured in microfluidic chips, and presented an insulin secretory response to glucose during fluidic experiments. Myotubes were successfully differentiated in microfluidic chips, and presented a measurable basal (insulin-independent) glucose uptake.- An in silico and in vitro informed MOoC scaling strategy was developed and implemented. A simplified in silico islet model was developed to rapidly explore chip designs. Corresponding in vitro insulin secretion experiments were conducted and confronted to the in silico experiments. Results raised the hypothesis that islets function was sub optimal when cultured in our low volume. Similar observation was made concerning myotubes scaling, where insulin-dependent glucose uptake was demonstrated in macro volumes experiments, but in micro volumes, the observed insulin response (only at physiological insulin concentration) has to be further repeated with improved experiments to explicitly demonstrate its presence.- A glucose biosensor compatible with microfluidic was characterized under different injection protocols, using in vitro and in silico experiments.- A multi-potentiostat was developed in the perspective of multiple and integrated electrochemical sensing in the MOoC.From the grounds and perspectives presented in this thesis, future work can be conducted to further complete this islet-muscle MOoC. The methodology can be re-used and extended in the perspective of adding new organs (liver, adipocytes) in this MOoC in order to better address the interorgan crosstalk deregulations in type 2 diabetes pathophysiology
