Research Summary

The Fazakerley group is interested in understanding the molecular details of insulin-stimulated glucose transport, and how this process breaks down in disease.

One of the ways in which insulin lowers blood glucose is through stimulating glucose transport into adipose and muscle tissue. Insulin achieves this by promoting the trafficking of the glucose transporter GLUT4 from specialised intracellular storage vesicles (GLUT4 storage vesicles) to the plasma membrane to facilitate glucose uptake. This process is impaired in insulin resistance, a state where the hormone insulin no longer efficiently lowers blood glucose.

Although we know that impaired insulin-stimulated glucose transport in muscle and fat is a major contributor to whole body insulin resistance, there is no consensus on the molecular basis for impaired insulin responses in these tissues. We use cellular and in vivo models and a range of techniques, including proteomics and microscopy, to reveal novel regulatory components of insulin-stimulated GLUT4 trafficking and interrogate how the insulin signalling network and GLUT4 trafficking apparatus are altered in insulin resistance
