High throughtput electrophysiological measurements coupled with transcriptomics to reveal cellular dysfunction in type 2 diabetes

Objective

In this project, I will develop methods to simultaneously measure transcriptomes with single-cell resolution and perform high-throughput functional measurements of individual pancreatic islet cells. I will focus on - and -cells which regulate glucose levels by secreting the two main glucoregulatory hormones -insulin and glucagon- and whose dysfunction is associated with diabetes. The islet is a highly heterogenous mini-organ, making it an ideal tissue to study the relationship between molecular and functional heterogeneity. It has been recently developed the use of patch-clamp electrophysiology and single-cell RNA sequencing (patch-seq) using whole-cell electrophysiology. In this work, I will combine high-density microelectrode array technology (HD-MEA) and transcriptomic methods to identify changes that lead to dysfunctional cellular states in type 2 diabetes. To do so, I will build a cell cherry-picking system to perform single-cell RNA sequencing after electrophysiological measurements in the same islet cell. Then I will use this system to investigate subpopulations of - and -cells that have been previously identified in human islets from donors with type 2 diabetes using transcriptomic methods, but whose implications in cell and tissue function are yet unclear.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.

Net EU contribution

Net EU financial contribution. The sum of money that the participant receives, deducted by the EU contribution to its linked third party. It considers the distribution of the EU financial contribution between direct beneficiaries of the project and other types of participants, like third-party participants.
