The long-term goal of this research is to further the understanding of pancreatic function and contribute to finding a cure for Type 1 Diabetes (T1D). Analyses regarding the differences presented in T1D and control donor human pancreas structures will be completed. The primary areas of interest include the intrapancreatic ganglia, neurons, synapse, and macrophages. Characteristics including size, shape, type, intensity, and location will be noted. This information will address whether the communication between ganglia and neurons with islet cells is normal in T1D patient or abnormalities exist.
