Beta-cell Response to Incretin Hormones in Cystic Fibrosis
In recent years, diabetes has emerged as one of the most significant co-diseases that many Cystic Fibrosis (CF) patients develop. Type 1 (T1D) and Type 2 (T2D) diabetes results when either the body does not make enough insulin or the body does not respond correctly to this insulin, respectively. Insulin is a hormone wh

| Summary | In recent years, diabetes has emerged as one of the most significant co-diseases that many Cystic Fibrosis (CF) patients develop. Type 1 (T1D) and Type 2 (T2D) diabetes results when either the body does not make enough insulin or the body does not respond correctly to this insulin, respectively. Insulin is a hormone which is made by cells in the pancreas and helps carry glucose (sugar) from the food we eat to the cells of the body for energy. While cystic fibrosis related diabetes (CFRD) has many features similar to both T1D and T2D, patients with CF may not have the same symptoms as either T1D or T2D patients. Currently, there is little understanding of CFRD and the best options for treatment remain unclear. The purpose of this research study is to examine and understand the various mecha |
