New mouse model may lead to new therapies for degenerative diseases

Most degenerative diseases begin with a gradual loss of specific cell types that progresses, eventually leading to symptoms. For example, in type I diabetes, hyperglycemia commonly develops when approximately 80 percent of the beta cells in the pancreas are lost; in Parkinson's disease, motor dysfunction typically begins when neurons in a certain portion of the brain are decreased by 70 to 80 percent. Finding ways to stop early cell destruction is vital, but methods to do so have proven challenging because of limitations of models for early stages of cell loss.
