Project description


Located in the Pancreas, the islets of Langerhans consist of the endocrine cells α, β, δ, γ, ε, of which the abundant β-cells secrete insulin as a response to nutrients. Insulin is then transported via the blood throughout the body and promotes glucose uptake in all cells. Under diabetic conditions of type 1 or type 2,  insufficient insulin secretion or a general desensitization to insulin, respectively, lead to hyperglycemia and ensuing pathological complications.

We are interested in understanding how insulin production, secretion and signaling are regulated in β-cells. An important player in these processes is the recently characterized Inceptor (Ansarullah et al., 2021), a protein highly expressed in the pancreas and other endocrine tissues, such as the hypothalamo-pituitary-gonadal axis. In β-cells, Inceptor at the plasma membrane promotes the internalization of insulin-receptor and therefore a desensitization of insulin signaling. Its further role in the dynamic activity of β-cells appears however more complex, given its high expression in intracellular compartments. Our aim is to decipher the involvement of Inceptor in the trafficking and signaling events in β-cells at super resolution levels.
