Currently, the only permanent cure for Type 1 Diabetes is a pancreatic or islet transplant. With the shortage of donors, we are progressing research towards alternative therapies by differentiating induced pluripotent stem cells into derived pancreatic β-cells that can be transplanted and used as treatment for Type 1 Diabetes. We are investigating methods to increase the yield of fully derived, insulin producing pancreatic β-cells and are additionally researching the use of hydrophilized expanded polytetrafluoroethylene for use in cell containment devices. These devices could offer a future alternative for islet transplantation in human patients.

Antibody microarrays are biosensors that have the potential to revolutionize molecular detection in medicine, scientific research, and national defense. However, current microarrays are not widely used due to problems including poor reproducibility and signal quality, unbalanced antibody performance, and cross-reactivity. Prior work in the area focused mainly on the stability of the antibody alone and not its affinity for its antigen. This presentation shows results of using molecular simulation to determine how different types of surfaces affect antigen binding to surface-tethered antibodies. The results offer an unprecedented, molecular-level view into these protein-protein-surface interactions and how to drive binding to occur.
